Tire Pressure #5

Closed sikrip closed 10 months ago

Is reading tire pressure data through can bus -> racechrono possible?

I found this resource https://www.ft86club.com/forums/showthread.php?t=113385&page=3 but I am not sure what needs to be done in order to get tire pressures to racechrono.

Thanks!

There are a few answers to this question: 1) Is it possible to get tire pressures via an OBD dongle in OBD-II mode? I believe it should be possible, but last time I checked I think there was a bug in RaceChrono's multipacket implementation. 2) Is it possible to get tire pressures in the CAN mode (the one you should use for data logging) using an off-the-shelf dongle? To the best of my knowledge, not currently. 3) Is it possible to get tire pressures along with other CAN data at all? Yes, via a DIY CAN reader such as https://github.com/timurrrr/RaceChronoDiyBleDevice. I didn't publish the code to read the tire pressures yet (I need to spend some time cleaning it up), thanks for the reminder!
