Has anyone managed to create a custom PID for engine oil temperature in RaceChrono for an FR-S/BRZ?
I’ve tried without luck.
I would be happy to test it too, thanks.
If you're ok doing some basic soldering, or have a friend who can help, you might consider creating a DIY CAN reader instead of using a slow and limited OBD protocol.
I've documented how to do it for FT86 cars here: https://github.com/timurrrr/RaceChronoDiyBleDevice
That is impressive work! I will look into it in more detail. As I plan to import also data like oil pressure (from an external sensor) and possibly more custom signals, I’d need to create a custom gateway between the car and phone anywho. Your work will most probably be very helpful.
And as the phone’s native gps has insufficient accuracy, I’d like to integrate also this project in some form: https://racechrono.com/forum/discussion/1746/my-first-build-can-bus-and-gps-through-bluetooth-le/p1
There is the https://www.wiveltracker.com/ which should be ready for sales soon, but it’s somewhat out of my budget and the diy route seems just too awesome (read: more time consuming and more expensive in the end) not to take it. €:
@timurrrr I am using OBDLink LX, which can read the oil temperature accurately and stably with its own app. But I’m not sure if there’s a problem with the device, I will try it with other app later. Any recommended apps ?
The OBDLink app polls data very infrequently, while RaceChrono does frequent polls, which might explain why you see failures with RC more often...
Do you also see the same issues with this channel when logging sessions, as opposed to the "Vehicle editor" / "Test connection" mode?
