Hey,
Has anyone ever used a Mototron ECM programming unit? it completely deletes the ECM and you have to program everything yourself. I've just been given the assignment of getting a 2.2L Ecotec I-4 running using that unit and my experience with engines has only been with my 65 Fastback and 71 Nova SS. Not so much with the whole electronics thing. I don't have any clue on fuel maps for the motor and Saturn, Chevy, and Pontiac are all being rather unhelpful in my search.
