Step 1: Set up Data Analysis System
34.40
| 00:00 | - The configuration step of the logger is something that's really critical to get right and it's also something that you need to spend the time back in your home workshop or garage making sure you get right before you actually head to the track. |
| 00:11 | You don't want to be setting up your logger for the first time after you've rolled the car off the trailer at the track, you're simply not going to give it the time it deserves or needs. |
| 00:19 | It's really something that needs to be done in a cool, calm environment where you've got no time pressure on you. |
| 00:24 | The reason it's so important is obviously if we head to the track and we've got a problem with our configuration, we're not going to get the data that we are looking for. |
| 00:32 | So that could be as simple as one of the sensors not being read properly or not being read at all or it could be as bad as the data logger never even turning on or starting logging at the start of a run and just not recording any data while you're on track which is obviously a massive problem and something we want to avoid. |
| 00:46 | One of the great things about the AiM Solo series is just the ease of use as far as far as actually fitting this thing to the car. |
| 00:52 | So it's actually almost a completely self contained unit, you can actually use it as completely self contained without needing to actually connect anything to the car. |
| 00:59 | The core of the system is a built in GPS sensor so that's doing GPS speed, it can do GPS based accelerations and everything. |
| 01:06 | it's also got an internal battery so if you charge it beforehand you don't even need to power it so it can be as simple as just attaching this thing firmly to your car somewhere. |
| 01:15 | It comes with a suction cup display so you can mount it to your windscreen and this thing can be mounted in a matter of minutes to your car without needing any extra wiring. |
| 01:24 | Now the way we've got it fitted is we do have the optional power supply fitted to it. |
| 01:28 | So that's just really nice, it means we don't have to worry about charging this thing. |
| 01:31 | We've also got some CAN data running to it so we've got the CAN bus running from the vehicle's ECU into this little logger and that means that we have opened up the number of channels that we can log massively over and above the built in channels that this thing has got. |
| 01:47 | Certainly one of the main advantages with a system like this is the relatively low overhead to getting started. |
| 01:52 | So as we'll see, it's pretty intuitive to go through and set this thing up in its software. |
| 01:57 | If you're not having to run any wiring to this it really can be a really quick process for getting up and going which really is the main advantage in using a system like this over something say like a built in logger that has to be wired fully into your car. |
| 02:11 | The different ways of being able to connect to loggers is different between manufacturers. |
| 02:14 | In the case of the AiM, there's no download cable or cable associated with plugging into this thing to configure it, it's actually all done over a local WiFi network. |
| 02:23 | So the logger itself has the ability to support its own network that you can then connect your PC to which is just connecting to the WiFi network of the logger and that's actually really really handy because it means you don't need to carry around any cables with you and obviously with all laptops these days, supporting WiFi it really removes one more barrier of things you need to remember to bring with you to the track. |
| 02:44 | So the way we go ahead and do that, first make sure you're not connected to another WiFi network, you can see we've got the WiFi networks locally in the building that we are and we've got the AiM Solo 2 DL followed by a serial number here, we just hit connect straight away and that should come up and make the logger available to us. |
| 03:01 | Now we've got a couple of different things we need to go through here. |
| 03:05 | This is a basic setup section so we've got our unit preferences so we can come through here and define which units we want to use for different quantities. |
| 03:14 | Whether it's pressures or speeds or temperatures, we've got the ability to come and define which units we want to use there. |
| 03:20 | The next section down is in the data download, so this is where we configure most of our default options for how we want the downloads to work, so here it's quite nice how they lay out how the folder structure works. |
| 03:32 | You can include which information will be included and how that information relates to the download structure which is actually a really nice way of showing this. |
| 03:42 | You've also got the option here of changing the order or how the hierarchy works for your particular folder structure so you can see here I've got the folder structure working by track, date, championship and vehicle. |
| 03:54 | We've also got some options here to define how each log file is named. |
| 03:59 | So again you can select what things you want included and change which order they'll appear in the file name which I think is a really nice idea. |
| 04:06 | We've also got the default download location here which is where all of the data will be stored. |
| 04:13 | One of the things that's a little bit unique about the AiM system is they do use a common database style way of storing all the data. |
| 04:20 | And we'll see that in a little bit more detail when we get into the actual analysis of the data. |
| 04:23 | Essentially the idea is that the analysis software will be looking at all of the different data that you've got available in your computer and then you can go through and filter by date, by car type, by driver, things like that. |
| 04:34 | We'll see that when we go and look at some analysis later on. |
| 04:38 | Can see back over here we've also got the ability to download what they're calling movies which is the optional Smarty Cam system that AiM offer which is the ability to nest video along with the data. |
| 04:52 | That isn't something that we've got configured in this particular setup but you have got the option there to do it. |
| 04:56 | Again we've just got another section here where we can define the session types that we want to use so you've got the ability to override these names but this is essentially just giving you a place to say which session types you want to use and that's just going to give us a different number of drop downs when we go and do the data download for ourselves. |
| 05:14 | lastly in the advanced tab here we've got the ability to change how different files are auto selected in the download section and we'll see a bit more of that detail when we go into the analysis section. |
| 05:25 | We've also got the ability to skip the selection of single lap sessions. |
| 05:29 | So that's a session where you're assuming that there's not going to be any useful data in there because if there's only one lap, the car hasn't gone out and completed any flying laps so you've got the ability to skip those, you've got some file merging options here and also the ability to export in different formats as well which ones you want to make active so for us, that's not important because we're just going to stay with the default AiM data source. |
| 05:53 | We've got some options here for sim racing so one of the nice things that AiM does is they integrate quite well with quite a few of the popular sim racing games. |
| 06:03 | So I'm not going to go through these options here but that is a nice feature that they offer. |
| 06:09 | We've also got some conversion options which again is related mainly towards the different racing platforms, so iRacing, Assetto Corsa and R Factor if you're using any of those platforms then you can come in here and the idea is that your analysis software, your AiM analysis software is going to know where to look to find those files on your computer. |
| 06:28 | You've got the ability to upload any custom tracks. |
| 06:31 | So if you have a got a track that's not in AiM's database, we'll see that a little bit later on in the setup but AiM does have an enormous array of tracks stored in their database so chances are if you're doing racing at a local track you won't need to make your own custom track for yourself but this just gives you the ability to upload any of your custom tracks to the AiM server to make it available to other people. |
| 06:52 | The next option is the WiFi settings which we don't need to touch for our case because I'm using this on a Windows based PC but there is some option in here if you want to use this software on a Mac, just about the WiFi connection settings that you can read about in the help file. |
| 07:04 | Down here in the screen image options, this is just giving us some options for which logo we want to use in the background here of our analysis so I'm happy to leave that by default but you can go ahead and customise that to whatever you want. |
| 07:16 | In the software behaviour tab we've got a couple of different options here, it's really just a case of more like preferences about the software so we've got options here about starting from the last page you used or starting from the start image so this is what I've got. |
| 07:28 | It'll start from the start image for my particular case and we've also got some option to inhibit the ECU protocol updates if you're going to be going ahead and updating your logger. |
| 07:38 | In the advanced tab you've got the option to important a whole lot of different elements there that are relevant to the software, whether it's cam protocols or different resources or update keys. |
| 07:46 | You can read all about those in the help file, I'm not going to go through them here. |
| 07:49 | So if we click on the configuration here, the idea here is that a configuration, and this is a similar concept to what a lot of other data analysis systems will use is all of the settings that you apply to your logger are going to be stored inside a configuration file. |
| 08:03 | And the idea behind that is you can take the configuration from one logger and apply it directly straight to another without having to go through and manually set a whole lot of things, it really does speed things up. |
| 08:12 | It also gives you the ability to have different configurations for different cars. |
| 08:17 | So with this logger being so quick to swap between cars, particularly if you're using the onboard battery, you can literally take this thing from one car and suction cup it to another, you might want to have a different configuration for a different driver preference, maybe you've got different settings that you want to use for different circuits you go to, maybe you've got different, if you're using CAN data from both the cars you're using this thing and you're going to need different CAN protocols that you're going to need to set up for each of them. |
| 08:44 | So the idea here is that it just makes it really quick to swap between configurations. |
| 08:47 | So that's what we see down here in the configurations. |
| 08:50 | There are 4 configurations here that I've got set up which is what I was doing when I first set this logger up and I've got a few different iterations here before we've got the final one that's actually stored in the logger itself here. |
| 09:02 | So along the top here we've got the ability to make a new configuration, we can clone a selected configuration if we want to do that, we can import it. |
| 09:08 | So if somebody gives us a configuration file on our PC we can use that to import that into the software. |
| 09:14 | We can export it if we want to export the software to share with someone else and we've also got options up here to receive or transmit from the current logger that we're connected to and also delete them from our history here. |
| 09:26 | So let's go ahead and connect to our logger so we've got it here in the list, I'm just going to press connect. |
| 09:31 | And we'll see what's going on down in the bottom left here. |
| 09:35 | Once this thing connects. |
| 09:37 | So now this is shown as a connected device so we've got the Solo here, Solo 2 DL and we click on it and it'll bring up what we've got currently being shown inside the logger. |
| 09:48 | So the first tab here is the live measure. |
| 09:51 | So you can see we've got the inline, the lateral and the vertical acceleration which for this particular logger are calculated from GPS coordinates. |
| 10:02 | So obviously these don't really mean too much while we're sitting here statically but essentially this page is just showing us the current values that we've got for everything that's coming into the logger so it's got some roll pitch and yaw rate values, the external and internal battery values. |
| 10:20 | We've got the ECU pedal position and ECU throttle position. |
| 10:25 | All the different values we've got coming in here over CAN are also shown to us live. |
| 10:29 | You can see some of these flicking between different values which is showing us that they're working. |
| 10:35 | We've also got the GPS, the raw GPS values shown down here and a little bit of GPS diagnostic stuff as well as some lap and run number stuff, lap time information so this is just essentially a summary of everything that's going on inside the logger at the moment. |
| 10:50 | We've also got some options here to force the logger to start recording and also options to make the device blink which is essentially showing it's live so there's a little bit of an override test that you might want to use if you want to use these functions here. |
| 11:03 | Coming across to the download tab here we've got all of the information that's currently stored within the logger so you can see it's organised by date here and within each date you've got different runs that have been recorded by the logger. |
| 11:16 | So we've got a little bit of information about the time and the date and also the size and the size of that file can be really useful for understanding how much data is logged in that file which again just tells you how much, if that is likely to be a useful data file to you or not. |
| 11:31 | Now the other thing to understand here is that all the data I've currently got in this logger, none of it is from actual track running sessions, this is all from stuff that's been recorded as the car's been sitting and being moved around the workshop but this value here is the number of laps in that run and this is where the best lap time would be shown as well. |
| 11:49 | So you can see here we've got the ability to select all, unselect all, select just everything from a certain run or just select individual runs. |
| 11:57 | Now we can do what we want with those, whether we want to delete them from the logger or download them from the logger, this is how we do that with these selection boxes here. |
| 12:06 | The next tab is to do with the WiFi and connection properties. |
| 12:09 | So we've got the device name here which I've left as default. |
| 12:12 | That's just the model of the logger and then its serial number. |
| 12:16 | We've got some options around how the power works, how the logger is configured which by default as an access point I've left all of that done as default. |
| 12:27 | I don't need to change any of that. |
| 12:28 | And also if you want to put WiFi password in there so that would be probably a good idea if you want to not have anyone else get into your logger configuration and change your settings on you, you can put a password in there. |
| 12:38 | You can also put some information in there in the properties, some default properties that will come in when you do your downloads. |
| 12:45 | In the settings tab we've got options to change the date and time format, which timezone you're in. |
| 12:53 | So for us, this particular logger's always going to be working in New Zealand where we're based but you've got options to change the formats there and also some options around the display, the backlight colour and how it's shown in the night vision options which you can read more about in the help files. |
| 13:10 | So the next one across is the tracks tabs. |
| 13:12 | So these are all of the tracks that are currently stored within the logger itself. |
| 13:15 | We'll see a bit later in the configuration section where we've got the options to download and get the tracks, the latest tracks from AiM themselves. |
| 13:25 | You can see also we've got some warning messages here. |
| 13:27 | The track that is stored in this logger is older than the versions we've got in the PC so that means we've updated the track library that's on the PC and they haven't been sent to the logger. |
| 13:41 | We've also got some options, sorry if we scroll down through here you can see quite a few of these actually need to be updated but you can see we've got 327 different tracks loaded in there at the moment. |
| 13:52 | Over in the counters tab we've got options to essentially record different trip meters or different odometers as far as how much work this actual logger has done. |
| 14:03 | So I haven't mucked around with these too much but you can see basically the system odometer has done 428 km since this thing was first fitted to the car and we've also got the option to configure some of our own down here as well. |
| 14:17 | The logo is as simple as the start logo that's used when the logger turns on so you'll see that pop up on the screen. |
| 14:23 | I've got our RaceCraft logo shown there so you've got the ability to show anything you want on there when the logger first starts up and you've got the ability here to select from what's on your computer, receive or transmit what's currently on the logger as well. |
| 14:40 | And you've got the ability to force it to show on the device so if I click this button here, I can see there on the screen, I can sort of preview what that looks like now. |
| 14:48 | The last tab here is just a little bit of information about the logger. |
| 14:52 | So the firmware tab it's got the device model, it's got the serial number, the hardware and a little bit of firmware information for us there, it's probably not something you're going to need a hell of a lot but it can be useful information if you're going through and troubleshooting problems later on. |
| 15:07 | So the first thing I'm going to do before we get into the actual configuration of the logger is import the current configuration that we have stored on this one. |
| 15:14 | So I'm just going to click the receive button here and that is telling us that it's successfully received, so that's this latest one here. |
| 15:21 | I can see that the time here matches the time on my clock. |
| 15:25 | So the first thing I'm going to do is just going to go and rename that before we make changes to this configuration so I'm just going to come in here and I'm going to update the date. |
| 15:34 | So the date today is the 13 of April and that is fine, that is for worked example. |
| 15:49 | I'm going to save that there. |
| 15:51 | So that means now all of the changes that we make in this configuration are going to relate to this particular configuration here. |
| 15:58 | Now all I need to do to open that up to start making changes to the configuration is we double click on it here. |
| 16:04 | Now we've got a whole new set of tabs that have opened up to us and one of the, if you're just getting used to finding your way around this software one of the things that might not be totally obvious to you is you can flick between these tabs, top left here so that goes back to the previous view where we've got the controls over the configuration file itself and up here which is the actual configuration that we're modifying. |
| 16:24 | So the first page that we're on here is the channels and these are the built in channels that are available to us from this logger. |
| 16:31 | So what we can see here is we've got RPM. |
| 16:34 | So this RPM's different from the RPM that we're going to go through in the cam setup. |
| 16:38 | This has got the ability to basically hardwire an RPM signal to the logger itself. |
| 16:43 | So that's just taking in RPM output, either from your ECU or directly from your coil or wherever you're getting it from. |
| 16:49 | You can actually run a wire straight to the logger itself and we're not using that because we're getting the RPM over the CAN system which we'll go through in a little bit. |
| 16:57 | We've also got the internal accelerometers that are built into the unit. |
| 17:01 | We've got the roll, the pitch rate, the yaw rate, the GPS information, so it's got a position accuracy channel, a GPS speed and also the altitude. |
| 17:10 | We can also see the frequency that each one of these is going to be logged at as well. |
| 17:15 | You'll see that if we click on any of these, we do have the ability to rename those channels but in these built in ones here we don't actually have the ability to update the frequency on some of them, if I go into the lateral acceleration here, we do actually have the option of changing the logging frequency that's used as well as the number of decimal places. |
| 17:33 | So that's it for the built in channels. |
| 17:36 | The important thing to note is these are the channels that we're going to log when we log our data regardless of if we've got no external data coming from our CAN bus or anything. |
| 17:46 | The next tab across is the ECU stream so the idea here is that we've got the ability to take data from the CAN bus, regardless of what your data source is. |
| 17:55 | So in our particular case, we've got a MoTeC M150 ECU running this car that's connected to the same CAN bus that our AiM logger is connected to and the idea here is that you've got the ability to select from a whole lot of pre defined templates. |
| 18:09 | So while you do have the ability to completely define your own CAN template if you need to. |
| 18:14 | In our case is was as simple as just selecting from the different options that are pre configured. |
| 18:20 | There's a massive library that we'll go through now and we'll have a look at. |
| 18:23 | So you can see here currently in the top, I've got this selected as MoTeC M1 so essentially you can think of it as a template. |
| 18:29 | So if you've got a MoTeC M1 ECU all you need to do is select that template and you should be pretty much up and go, ready to go from the start but if I click on change ECU button here, you can see there's an enormous selection of different manufacturers, whether it's aftermarket, logger or component manufacturers or even OEM manufacturers. |
| 18:45 | So we've got 2D which is an aftermarket logger company, we've got AEM, we've got AiM itself. |
| 18:50 | Bosch, Citroen, enormous amount of manufacturers here and within each one of the manufacturers you can see there's a different list that will come up. |
| 19:01 | So currently I've got MoTeC selected as the manufacturer and these are the different MoTeC pieces of hardware that AiM is predefined to configure with. |
| 19:10 | So I've got the M1 with a baud rate of 500 kb selected and that is the system that I'm going to be using, that's the way I'm going to be doing the interface between the MoTeC and the AiM. |
| 19:21 | Now if you've got something that's not included in any of these lists, you've got two options, you can either ask AiM to make one for you and depending on their ability to be able to do that for you, they may be able to make that CAN template for you. |
| 19:33 | You've also got the ability to make a custom CAN template which we'll see a bit later in the configuration as well. |
| 19:39 | But for now I'm going to leave that selected by default 'cause this is all up and working for me but the other thing you can see is if we scan through this list of the default template, you've got this check box here and this is giving me the option to just log the channels that I'm interested in logging so I've got ECU RPM, ECU gear, different wheel speeds, oil temperatures and pressures. |
| 20:01 | All of these are not necessarily important to me but we have got a little bit of flexibility depending on what we want to log here and which rate. |
| 20:09 | So all we need to do here is double click on it, we've got the ability to rename, essentially give that channel a new alias. |
| 20:15 | We can change the sample frequency if we want to and we can also modify the unit of measure if that's required. |
| 20:21 | We've got some more CAN confirguration options here, they're going to be useful in some cases depending on how you've got your CAN bus set up. |
| 20:28 | I'm not going to dig in in detail into configuring a CAN setup here for this logger. |
| 20:32 | But chances are if you're using something common, which most people will be, all of this stuff will work out of the box and you won't need to get too carried away with different CAN configurations anyway. |
| 20:45 | The next tab across is for CAN expansions, so there is the option to add in LCU 1 which is an AiM product to interface that directly with the CAN. |
| 20:53 | It's not something that we're using in our particular case so I'm going to skip this. |
| 20:57 | Now the math channels, this is a place where you've got the ability to computer onboard math so you can see we've got basically these different templates for defining different types of math. |
| 21:09 | The idea here is that if you calculate them onboard inside the logger they're then going to be available to you inside the analysis software so we've got a bias calculation, bias with thresholds so the bias, that's just saying when some condition is true, only compute the bias channel. |
| 21:24 | We've got calculation of gear, pre calculated gear, a linear correction, a simple operation as an addition or a subtraction or a division and then options to do some bit math as well so I'm not actually using any math built into this thing but let's quickly go into one of these calculations and see exactly how that works. |
| 21:45 | So I've got the option here to rename the bias channel, so let's say if I wanted to do a front to rear bias, brake bias calculation I could come in here and rename that as brake bias here. |
| 21:55 | I can define this sampling frequency it's going to be calculated at, the units of measure, the number of decimal places and I can also come in here and select from our channel list. |
| 22:03 | So we've got the different channels that we may or may not have access to. |
| 22:07 | So we've got the internal channels here, starting from the bottom, that's the battery, we've got the gyro channels, accelerometers, GPS channels, the lap channels, so this is things like current lap times, best lap time, rolling lap time. |
| 22:20 | And what we're going to use in this case is the ECU channels so this is everything that's available coming to us from our CAN template from the CAN bus. |
| 22:27 | So if we come down here to brake pressure front, we can select that one and we can come back up to here and brake pressure rear and now we've got, it's channel one, this sort of math is pre defined for us, the value is going to be equal to channel 1 divided by channel 1 plus channel 2. |
| 22:43 | So in this case it's going to take the front brake pressure divided by the total brake pressure which is the sum of the front and the rear brake pressure. |
| 22:48 | So that is how that channel would work and now that's available for us to log in the logger and we'll get that come through in our analysis. |
| 22:55 | We've got some different parameters here for setting up of the logging. |
| 23:00 | This is a really important step for making sure you get right. |
| 23:03 | We've got the options here for hold lap time so that's just when you cross the finish line at the end of each finish line we have got the screen up here which is a really nice feature of this little AiM system, it means that the screen's build into it and it can give us lap time feedback so this hold feature is going to show us what the last lap time was when we cross the start/finish line and this number here is going to, how long, it's going to tell logger how long to show that lap time for so it's going to show for 10 seconds after we cross the finish line at the end of each lap. |
| 23:32 | We've also got the ability here to change the track width so that is essentially changing that gate width that we talked about within the course of how wide the detection radius is around the start/finish line, definition for the GPS. |
| 23:44 | We've got the ability to override what's used as the reference speed channel. |
| 23:47 | So by default here it's used here as GPS speed but we have got the ability if we tick this to come in here and select one of the different speed channels if we wanted to. |
| 23:55 | We're not going to use that, we're just going to leave that as the default GPS speed. |
| 23:57 | We've also got the ability to change when the data logger stops and starts. |
| 24:04 | So this is really important to get right to make sure that the data logger is going to be starting recording when you want it to. |
| 24:10 | So the standard conditions that I'm going to leave by default here, when the engine RPM is greater than 500 or the speed is greater than 10 km/h. |
| 24:20 | So that's what it's going to use to start and stop the log files, what's going to define a run. |
| 24:25 | We've also got the options down here to do our custom conditions so we can do, it's a little bit of custom math here to say in this case it would say, this is using something similar to the default math but you've got the ability to customise different parameters and making the logger start and stop when you want it to. |
| 24:43 | The next tab across is showing us the behaviour for our LED bars. |
| 24:48 | So this is what the actual unit looks like, we've got this generic display in the middle here we can use to show all sorts of different information but we've also got these coloured LEDs up the side here and we've got 2 main uses we can use those, we can use those for predictive lap timing or we can use those as gear shift lights depending how you want to use them. |
| 25:05 | So for our case we're using this for the predictive lap timing and this is showing us basically these lights will give us a colour to show us how we're going relative to the best lap time that we've currently got stored in the unit. |
| 25:15 | So going through the options here for the gear shift lights. |
| 25:18 | We've got options to define whether the lights are going to stay on when they get exceeded. |
| 25:22 | So what I mean by that is each time you get to each one of the thresholds, whether that previous light is going to stay on or whether you're just going to flick to the next one so you're only going to have one LED on each side showing at a time. |
| 25:31 | We've also got the ability to modify which RPM channel is going to be used to trigger these lights so in our case we've only got 1 RPM channel configured and that's coming from the CAN bus so that's why we can't change that here. |
| 25:42 | We've also got the option to do gear dependent shift lights. |
| 25:44 | So by default here this is going to, regardless of which gear we're in, each one of these lights is going to come on, each one of these settings here. |
| 25:51 | We've also got the ability if we connect, put gear dependent shift lights in here, if we change the number of, if we've got let's say a 6 speed transmission, we can have a custom RPM range that's going to work within each gear. |
| 26:05 | So that's going to be really important if you're trying to tune your shift lights really accurately because in reality you have a different acceleration rate for each gear so the lower gears the amount of torque that you've got available to the wheels is going to change the acceleration rate of the car, it's going to be higher in lower gears where you've got more torque available to the tyres. |
| 26:23 | One of the ways people often want to make their shift lights work is to have each section of the shift light stay on for a constant amount of time regardless of which gear you're in. |
| 26:31 | So that means that you're going to have to adjust how long they're on for, adjust the RPM range, whether you're in lower gears compared to you're in higher gears but we're not going to use gear dependent shift lights so I'm just going to leave that turned off there because we're actually using this for predictive lap timing. |
| 26:48 | Now on the display, this is where we've got the option to change the way different display pages work so you can go through different display pages, you've got different preset options you can have here and this is one of the ways we can set that up. |
| 27:00 | So by default here the only page I've currently got set up is a page that's currently showing us how we're going relative to our reference lap time. |
| 27:09 | So the important thing to understand here, so if I click, make this part of the screen active, you can see we've got the ability to select from different parameters here. |
| 27:19 | There are all the different parameters we've got access to so whether they're coming from the ECU, whether they're coming from the lap channels, GPS, accelerometer, the gyro, anything internal or any math channels like our brake bias that we've got defined there. |
| 27:31 | So for our particular case, we're using the delta to the best time which is what this is shown as and we've also got the ability to customise those if we want to so if we want to change any of those, say for example this little PT down down here we can change that if we need to. |
| 27:47 | And we've got the ability to show or hide those as we want to as well. |
| 27:51 | So if we're going to go here and let's say we want to add another page, maybe for the case of engine reliability. |
| 27:58 | So we are bringing in CAN bus data so we can add that here so let's add a new page, give ourselves some options. |
| 28:04 | So we've got a number of different pre defined templates here, so just showing one value which is what I'm using to show for the delta value because I just want it to be nice and big and easy for the driver to see which is the main one we're going to be using when we're on track. |
| 28:17 | I've got 2 values, 3 values and 4 values so if we go here and check 4 values here. |
| 28:21 | So now we've got the ability to select each one of these areas and define which parameter is shown in it so I'm going to use these for reliability channels so I'm going to come in here and I'm going to select, what shall we use for start, engine so the ECU engine coolant temperature. |
| 28:35 | That's going to be one and the second one I'm going to choose the ECU or engine oil temperature. |
| 28:43 | The third one I will put the gearbox temperature and in the fourth one I will put the inlet air temperature for argument's sake. |
| 28:52 | So now we've got the option to come through here and customise any of the, whether we want to show the units or not as well as the little prompt that we've got here down here, so we could put coolant if we wanted to and that will be shown here. |
| 29:06 | However you want to customise that and the idea here is that then the user can go manually thumb through different displays depending on what they want to show so you can add a number of pages on here depending on how you want to set your logger up. |
| 29:20 | We've got a tab here for the Smarty Cam so that's what I talked about before where AiM has got its own camera system which is designed to work alongside any of the AiM products. |
| 29:31 | That's not something we're using so it's not something we're going to go and set up here but this is essentially where you would go through and configure everything about the Smarty Cam system if you're using it here. |
| 29:40 | In the last tab here is a bit of an advanced feature, it is essentially a CAN output. |
| 29:45 | So everything we've been talking about with CAN so far has been to do with the input CAN side so that means taking data from the CAN bus. |
| 29:52 | We've also got the ability to output data if we wanted to have specific CAN data we wanted to spit out and use in another component of the car, we've got the ability to define that here. |
| 30:01 | Now some of the other options we've got inside of the Race Studio software, we've got the ability to click this button which will take us to the Race Studio analysis software which we'll go through in a later step, we don't need that for the moment. |
| 30:13 | Here we've got the options to look at the different track options that we've got stored on our PC if we want to modify those or import any, here's where we can come and do that. |
| 30:24 | So you can see we've got everything by default organised by country here. |
| 30:30 | Now if we're looking for a specific circuit, so let's say we're looking for Sebring, we can see the two different configurations that are available from Sebring straight away. |
| 30:40 | If we wanted to go to a European circuit, we can see everything that's coming up underneath Spa. |
| 30:47 | So we've got actually two of the different karting configurations as well as the main Spa circuit itself so absolutely enormous amount of tracks that we've got predefined in here and you can come through here and make modifications to those if you need to. |
| 31:04 | Chances are you're not going to be needing to do that if you're using, you're on a normal circuit, you're not going to be needing to come through and change any of these values that are already included in the software for us. |
| 31:15 | The next tab across is what they're calling the movies tab which is to do with the vision that we'll be recording from the Smarty Cam system but as I discussed, that's not a system we've got set up on this logger so it's not something we're going to be going through. |
| 31:26 | OK the next tab we've got across here is for custom sensors so if you've got any specific custom sensors that you want to set up inside your logger, this is where you can do that. |
| 31:35 | So let's go ahead and make a new collection, I'm just going to make this a test because we're not actually going to set anything real up here but I just want to show you guys how that works. |
| 31:43 | So these different collections, they're different ways we can organise the sensors and then once we've got that collection selected we can come here, new and we're going to say my pres sensor for argument's sake, we'll set up a dummy pressure sensor here. |
| 31:55 | So we've got the option to select the measurement type that we're doing and that is pressure so that's shown here, we can choose from the different calibration type, we've got the ability to define whether it's working over voltage or resistance. |
| 32:07 | Also the options if you want to use a pull up resistor or not and here is where we can enter our values for the calibration. |
| 32:15 | So if you're using something like and off the shelf pressure sensor, this is something where you'll be able to get the spec sheet and be able to type these values in manually so for this case I'm going to assume that we've got a completely linear sensor that operates completely linearly so if we say that the, it's from 0-5 volt range here and let's say that the 200 bar is at the other end of the spectrum at 5 volts, that's how we would come through and define the relationship for that sensor. |
| 32:44 | So then we can come through and save that and then that's going to define the behaviour of that voltage behaviour for us. |
| 32:50 | The next tab across is to do with defining custom CAN behaviour so that's not something I'm going to get into here, it's more of an advanced topic but that is something that there is information included in the AiM help documentation if you need it. |
| 33:04 | Lastly up here we've got a couple of buttons, we can click this one to see which WiFi networks we've got available to us and if we're connected, this is one of the ways we can see whether we're connected to the device at the moment, we can see we're currently connected to the AiM Solo. |
| 33:17 | We've got the options here to get updates for the software, updates for the ECU protocols. |
| 33:23 | That's the different ECU templates that, if you click this, obviously you have to be connected to the internet when you click that and that's going to resync the latest ECU protocol database for you and you've also got to link to the AiM website here which is one of the ways you can go through and find the help file for your particular product that you're using. |
| 33:45 | So that's really it for showing you guys how the AiM software works and how we go through and configure the different options of the logger ourselves. |
| 33:51 | There's one more step that we need to do before we know we're ready to head to the track and that is making sure we have cleared all of the logged data that's currently stored in there. |
| 33:59 | You don't have to do this but this is my preference to start with, bit of a clean slate so that I know I've got no old logged data in the logger. |
| 34:06 | So if we come across to my laptop screen here, here we can click on this box here, this is going to select all of the bogus data that I've got in there that I know isn't anything useful and I can just come up here and press delete. |
| 34:19 | Yes I want to delete the selected files and that's going to go through there and delete all of that stuff off the logger. |
| 34:25 | So now that we've got no log files left on the logger, we know we've got a completely clean slate, we know we've got all of the logged memory available to us we will need and we are ready to put the car on the trailer and head to the track and gather some data. |
