Custom OBD2 PID

pan_dodo

Hi,

I’m using:
App: RaceChrono for Android with Devices Pack
OBD reader: ELM327
Car: Toyota GT86 2017

I’d like to add a custom OBD2 channel. In the Channel Editor I can configure all the parameters, and I see plausible live data. However, in the session data the value for the custom PID is always shown as “–”.

Do I need to purchase RaceChrono Pro in order to have this feature enabled?

Thanks!

just guessing: That source equation will always return 1 kPa = 0.01 bar (regardless of the input). The display is set to 1 decimal in bar. 0.01 bar gets rounded to 0.0 bar and displayed as "--".

Thanks for your comment.

I repeated the test with a constant value of 100, which should have resulted in 1 bar, but without success. Again, only “–” was shown.
To be sure, I added a reasonable equation, but once more there was no change.
