Popping and loading up?!?!
Of, i finally got the car to idle and i figured out how to keep it from dumping fuel in after it warms up. I have some issues that might be easy for some of you more experienced guys to figure out.
i have a 12:1 CR LME 408 Stroker in an A4
Im running a Vic Jr. Style intake
TFS 225 heads
SD Tune
I ended up haveing to raise the VE tables 10% from 400 - 2000 RPM to keep the STFT's close to Zero, which allowed the LTFT's to stay at about -8.6...most of the time anyways..
I know im still reading a little lean..
But, I took the car on a little test drive, and the car would sputter and backfire in the lower RPM's Loading up and blowing black smoke..
I obviously am running too rich in the lower RPM's based off of my raising the VE Table 10% to get it idle without leaning out..
I just cant seem to find the happy medium..
What am i doing wrong?
Thanks,
chris
