1. Set up Data Analysis System


00:00 - At this point in the course, you should have a thorough understanding of how a datalogging system works and you should also understand some of the key skills we're going to be using in order to find areas to improve on on track.
00:13 It can still be difficult to initially decide what to do and how to progress which is why we've broken the data analysis process down into a simple to follow 6 step process.
00:25 By following this process from start to finish, it will ensure that you log high quality meaningful data that can be used to help improve your lap times.
00:34 It will also give you a quick and easy way to focus on the areas where you stand to gain the most time and show you what you need to do in the car in order to achieve potential gains.
00:46 This is an iterative process that you can keep running through as you hone your driving and shave down your lap times.
00:52 We'll start with the first step which is to configure your logging system before you head out on track.
00:58 Some of this will involve some initial installation and configuration of the inputs and sensors so that you can be sure that the data you're logging is accurate.
01:06 This also involves setting up suitable logging rates for each of the channels which you're logging which we discussed within the body of the course.
01:14 With a basic standalone logger, there's very little to do here other than securely mounting the logger.
01:19 However once you start bringing in additional sensors and ECU data via CAN, the workload here can increase dramatically.
01:28 The good news is that this is a task that only needs to be completed once and you won't need to repeat it every time you go to the track.
01:36 It pays to take your time and check each individual channel to make sure the data you're seeing makes sense or is in line with what you'd expect.
01:44 Once your initial setup is complete, there's still some work to be done when you're ready to head to the track.
01:50 Depending on your particular installation, there may be a number of sensors that should be zeroed once you've got the car unloaded from the trailer and are ready to head out on track.
02:00 An example of this could include zeroing your three axis G sensor, your steering position sensor and your damper position sensors if applicable.
02:08 The next task is to ensure that you have the correct track details set in your logger.
02:12 In some instances, with a GPS based logger, this will be automatic since the GPS knows exactly where the car is.
02:19 In other instances you may need to specify the track as well as the GPS coordinates for the start/finish line.
02:26 You can see how this is done in the practical skills section of the course.
02:30 If you're using a timing beacon, then you'll need to make sure that it is set to transmit on the correct ID and place it at suitable location on the racetrack.
02:39 It's always a good idea to actually test the beacon and receiver by moving the beacon past the receiver in the pits before placing it trackside.
02:48 This will ensure that you don't miss any lap times during a session.
02:52 The last task before heading out for your first track session is to clear any exisiting log data and send through a reference lap if relevant.
03:00 Then you'll have the ability to view a lap gain/loss while you're on track.
03:05 At this point, we can be confident our basic setup is complete.
