2017 Mustang ROUSH OS throttle closing issue
Hi everyone,
I have a 2017 roush mustang with headers only. Pulled the stock file and made some changes to the MAF Based on the STFT they were pulling 10% fuel......corrected this wrote the file throttle started closing at high rpm 6300 kept chasing it with no luck.....wrote back stock tune throttle fully opens but MAF but trims r out!!!!!
THROTTLE CLOSES When MAF saturated shows up
I tried lowering default periods 75. i tried to disabled MAF saturation under airmass limits ......really weird i kept everything stock but changed maf correction and same issue i evem tried to rescale maf periods still same issue!!!
