When engine comes off RPM, duration gives a rich signal and causes ecu to correct , giving the engine less fuel. Stalls out. You will have to play fuel trims, AFR, and throttle position adjustments below 1000-1200 RPM, etc. Not easy to tune at all  |
hello
it goes really nice on both idle and midrange but at wide open trottle it goes very rich.
