Post Read first: OBDII PID mapping 
Common SAE standard OBDII PIDs covering RPM, TPS, Engine Temperature and others already exist as presets in the RaceCapture system, but it gets interesting when we can start extracting OEM specific OBDII data.

The RaceCapture system starting with firmware 2.11.0 and app 1.9.0 provide the ability to perform custom OEM PID requests - commonly known as Mode 22 (aka hexadecimal 22) and will be able to unlock additional data from the ECU.

Some manufacturers provide this information freely, but more often than not, PIDs need to be reverse engineered, and much research has been done in this area already.

You're welcome to post here for inquiries, sharing research on existing OEM PIDs and results from your own testing and reverse engineering.
