Dolan Posted November 10, 2020 Posted November 10, 2020 (edited) I have a similar issue with my car and a mates car. When I try to tune the injectors to a different fuel pressure or when I have different injectors and fuel pressure I get decent lambda on idle but goes very rich when the throttle is touched. I've checked the fuel pressure and it is rock solid (using a GFB FPR), disabled closed loop fuel. STFT, LTFT and commanded lambda is dead on 1.00. Also when I data log the the injector pulse width hardly changes (1.6667% to 1.9444% duty cycle) I'm stumped at the moment, I've checked everything, gone through all the forum posts and tried everything I can think of, but I know I'm missing something. Any help would be very greatly appreciated! Video Edited November 10, 2020 by Dolan Quote
Roland@pcmtec Posted November 10, 2020 Posted November 10, 2020 As soon as you touch the throttle the cam timing will change. Do a scatter plot of rpm vs cam timing vs ltft and see if it's correlated to a specific speed density cell. Quote
Dolan Posted November 10, 2020 Author Posted November 10, 2020 It doesn't really show much as my LTFT and STFT are both disabled. And I don't have a O2 sensor plugged in either Cam Timing 01.csv Quote
Roland@pcmtec Posted November 10, 2020 Posted November 10, 2020 Then graph it against your wideband instead 1 Quote
