Ok. I’m in the process of tuning my 85 G20. Early Crate 350 with 7747 ECM. most of the fuel map and timing is good but warm idle has a slight miss. Ive read bpw can do this. Mine is in the 140ish range. If i wanted to decrease bpw, by how much do i need to increase ve1 or ve2 to compensate and keep the fuel map close to the same?
thanks
