Does anyone have a copy of a GMPP Crate LT4 3 pin manual tune?
GM Numbers: 19366789,19368843 or 19370326.
I think the Auto OS is pegging the speed at 158mph and limiting RPM to 4k.
Think it has to be the GMPP as there are no 3 pin digital sensor tunes that are e92, they are all e92a if I'm correct?
GMPP Dry sump LT4 crate engine- 3 pin fuel press sensor- correct 3 pin manual loom - incorrect ECU from GMPP LT4/8L90 - C6 Z06 T56 & Diff
All in Aston Martin Vantage.
Also fighting throttle hang but looks to be in the torque tables looking at other posts but will chase that once the correct tune is located.
Many thanks.
