This is the question i have been wondering... being OBD it "should" be standard but that doesn't mean anything....

Anyone have a clue what it is actually sending?

In the Settings in Torque you can change all the units, including the one from CFM to gammes/sec.

For our purposes that is useless as the base reading is wrong.. I found the standard calculation used ((A*256)+b)/100 .. I'm going to dump the raw values (A and B) and see if I can tell what it "Should" be

Ok, so far it seems that A is always 0 ... B is the only one that has a value, so it is definitely an issue with our ECU reporting non-standard data.
