Dolan Posted November 10, 2020 Share 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 Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 10, 2020 Share 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 Link to comment Share on other sites More sharing options...
Dolan Posted November 10, 2020 Author Share 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 Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 10, 2020 Share Posted November 10, 2020 Then graph it against your wideband instead 1 Quote Link to comment Share on other sites More sharing options...
