34_40, thanks for the link. Not sure how applicable it is to the SFM ECU I have but it verifies the wiring probably came with the computer from Accel.
The van has a 700R4 in it, confirmed that last night. I'll be working with a friend of mine, Kevin. He owns Performance Fuel Injection Systems and he thinks we can build a computer to run the engine AND be tunable. We'll see how it goes.
