Once we have some logged data that we want to download from the ECU, we need to go online to the ECU and we can either choose ‘Retrieve Logged Data’ from the ‘Online’ menu here, or alternatively use the shortcut ‘Control’ and ‘F8’.
|
00:16 |
This will start the log file download process and open the ‘Retrieve Logged Data’ window.
|
00:23 |
The first step is to select which logging systems we want to download.
|
00:28 |
For Logging Level One and Two, there is only one log set available which is ‘Data Logging System One’.
|
00:34 |
If we have Level Three logging, we can choose which log systems we want to download by ticking the appropriate boxes.
|
00:42 |
We can now click next to continue the process.
|
00:46 |
The next window will ask us if we want to delete the logged data after it is downloaded.
|
00:52 |
This will clear the logging memory, ready to log fresh data so we would normally want to do this when we are downloading the logging.
|
00:59 |
We can now click ‘Next’ and the logging will be extracted from the ECU and the data will then be erased if we had ticked that box.
|
01:08 |
Once this step is complete we can again click ‘Next’ to move on.
|
01:13 |
At this point the logging has been retrieved and we no longer need to be connected to the ECU.
|
01:18 |
This can be handy if you are downloading data in the pits as you can now disconnect and allow the car to get back on track.
|
01:26 |
At this point the logging is downloaded but it is stored on the laptop as a logging image.
|
01:32 |
The next step is to convert the logging image into a proper .ld file that can be opened and viewed in MoTeC’s i2 analysis software.
|
01:41 |
We can choose to convert the file now or it can be done at a later date.
|
01:46 |
We are going to continue and convert the file into a log file now.
|
01:52 |
Next we can add some comments that are relevant to the particular log file.
|
01:57 |
It doesn’t take long to end up with a lot of logged data, and it is good house keeping to use a sensible and descriptive comment so that the file can be easily identified later.
|
02:08 |
The ‘Short Comment’ is what you will see in the details summary when you open the log file.
|
02:14 |
We can also add a longer more descriptive comment which may include key points about the car setup or the test session.
|
02:22 |
We also have the option to add a vehicle, driver, venue, event and session.
|
02:29 |
Filling these out correctly makes it easier to identify a particular log and where it has come from.
|
02:35 |
This becomes important when you are dealing with hundreds of log files.
|
02:40 |
Lastly we can choose a particular folder to log to if desired.
|
02:44 |
By default, all the log files will be sent to the ‘logged data’ folder but we can add extra folders if desired to separate different vehicles or different customers to make it easier to find and navigate through the log files.
|
02:59 |
Once we have filled in the relevant details, pressing next will begin the conversion process.
|
03:05 |
Once the conversion process is complete we will have the option to open the log file directly in i2, ready for analysis.
|
03:13 |
Alternatively if we don’t want to analyse the data immediately, we can click close and open the file manually at a later point.
