Hi all,

I am working on OBD. I am passing standard PID's and response also I am getting using PCAN-USB (https://en.wikipedia.org/wiki/OBD-II_PIDs) . My task is to calculate fuel consume by the vehicle so please help me with that. I was wondering where I can find custom PID's.

Thank you.

First off, to calculate fuel consumption, we at BAT auto need some basic info.

Such as engine size!! Who made the engine and all that fancy jazz.
