Hey guys im in the process of tuning this trackhawk, it has 10%lower pulley, 2.95 upper pulley, fic 1300 injectors and full exhaust, i noticed that on straight fuel my trims where very close to 0, so i know injector data is ok, but when i turned flex fuel on, i couldnt correct this three things:
1)It will learn alcohol content and then reset to 0% alcohol when i stay at steady throttle.
dyno12.hpl
2) Still when it didnt reset to 0% i got pretty high stft corrections
dyno9.hpl
3) Throttle wouldnt open to 100% until 4500rpm
(see any of the logs above)
Any idea on what is out of place in my flex fuel settings to make me do that?
I cant find any "source" or flag on the scanner to guide on what is limiting my throttle opening before 4500 rpms, any ideas?
here is the tune
