Engine cuts out after 1/4 throttle
Posted: Tue Oct 13, 2020 8:28 am
Recently installed an S300 on my P28. Engine ran fine prior to S300 install and I'm not sure what I did and how to fix it. The engine cuts out after 1/4 throttle, and occasionally dies out. Sometimes it will come back on and lurch then quickly cut out again.
I saw on some other threads it was the TPS. I performed the TPS calibration. It still does it. I can see the values in datalogging with engine running so I'm not quite sure why this is happening.
What other troubleshooting steps should I be doing?
P28
Yes J12 is cut
TPS has been calibrated from sManager (-0.48% / 101.57%)
Using base P30 map with ELD and Knock disabled
Custom wire harness on race car
Rywire engine harness to P28
Stock everything
Stock OBD-II injectors with OBDII\I conversion harness on injectors
