after tripping my sons cold start valve on his MC motor under boost with a button controlled injector driver I have come to the conclusion that Scott J.(q-ship) is correct, the # 5 cylinder receives no additional fuel so we are working on a up stream application of fuel, complicated by the fact he has a vented to atmosphere by pass valve,,, yeah if we introduce the additional fuel before the throttle plate and when the bypass valve opens,,,, whoosh with a flammable mixture! we are working on it. Scott was right on, and not to start a war, umm Phil was wrong about why the cold start valve function was moved to the control unit in the MAC 12 and 14, it was only for starting, not boost enrichment.
