Hi Bob,I think I know what you're talking about, and I think it turns out to be "Airflow" - which is used for EGR calculations. If the address appears in byte 37 in the datastream, it is indeed airflow.

That is good to know, thanks Jeremy, Ludis. I've been doing a hac on it, and was wondering how useful it would be to others. Ludis, maybe you can help me a bit more. . . In part of the code, they do a calc where several items are multiplied together, with the result used to do table lookups of various filter coefs. Mult together: bpw, cylinders mask, afr, rpm, along with some constants (200d, 218d, 120d). Would you have any idea what this would be? Thanks, BobR.
