Custom PID help

Post by jamcgowen » Thu Sep 06, 2018 2:44 am

[Moved to Accessories / OBD forums]

Sorry in advanced if this is not the right place for this post. I was hoping someone could help me figure out what im missing or getting wrong in setting up a custom pid. I am tryin to program a pid to display my car's (e46 m3) oil temp. So this is what i have so far...

Channel: Oil
ECU: EOT *idk if thats right*
Mode: Mode 1
PID: 5C92... or is it 0x1 0x5c?
Request Frequency: Low
Formula: ?

this is where i got the information for the Mode and PID:

Instructions on Custom PIDs are available here: http://www.gps-laptimer.com/LapTimerDoc ... rogram.pdf

Please note we cannot help on individual / car specific codes. In case you have the complete information available, we will certainly help to specify it in LapTimer and trouble shoot if necessary.

Unfortunately I'm not sure who this custom PID feature will be helpful to, I have not come across any information other than PID values which is not enough to get this working.

Yes, but at least for Ford, GM, and Toyota drivers there is plenty information available.

so here is a question... i have a schwaben scan tool and it is capable of pulling the oil temp in the live data view. so clearly there is a way to access that info, does anyone know if you can view the parameters used by schwaben scan tool to pull the oil temp data? I've been trying this based on the pdf.

Channel: Oil
ECU: EOT
Mode: Mode 1
PID: $01$5C
Request Frequency: Low
Formula:

Ive tried changing the ECU, but that doesn't seem to make a difference.

This is the OBD II standard PID for engine oil temperature. If available, LapTimer pulls it automatically. No need for a custom PID in this case. See https://en.m.wikipedia.org/wiki/OBD-II_PIDs for the list I Standard parameters.
