E36 fuel consumption protocol
I have a British 1992 E36.
I am using the engine in a kitcar and would like to read out the fuel consumption with an arduino.
I already figured out the engine communicates the fuel consumption to the OBC and that this information passes through wire 24 of the main engine harness connector X20. What I don't know however is the protocol it uses.
I suppose it will be digital. Is it a puls per ml or something?
Can anyone confirm this?
Thanks in advance,
