FR-S/BRZ Oil Temperature PID

stewart23

Has anyone managed to create a custom PID for engine oil temperature in RaceChrono for an FR-S/BRZ?

I’ve tried without luck.

Hi, I've emailed you about the problem with OBD-II header. The OBDLink screenshot had 7E0 for the header (and 0x2101 as PID and "A-40" as equation). Unfortunately RaceChrono currently uses the default OBD-II header only, so this doesn't work at the moment. Next version (v6.1) will add this functionality.

Looking forward to 6.1! I just got a new car and all of the custom PIDs are 7E0 headers as well. Will be happy to test out on the beta when it's out.

I would be happy to test it too, thanks.

Sure, it will be first available in Android beta group. I can make it available for iOS too (Test Flight) if anyone needs it.

@aaronc7 @stewart23 v6.1 has now been uploaded to the beta group (Android only). Let me know if this works now.

Using the latest beta that allows for custom PIDs and ODB2 headers, I got my oil temps working with these settings:

Screenshot: http://bit.ly/2MYpzQv

Channel: Engine oil temperature (C)
Channel Postfix: None, None
ODB-II Header: 0x 7E0
PID: 0x 21 01
Equation: bytesToUInt(raw, 28,1)-40

The equation AC-40 floating around doesn't work because there is no variable AC in Racechrono, but AC refers to the 29th byte of the raw frame-message, so to get the 29th byte we use 28 (Arrays start with 0) in the function bytesToUInt to get the equivalent AC value.

@Deisou Thank you, great job figuring this out!
