Question About Long Term Fuel Trims
I have an 06 WRX with a VF39 and tial 44mm EWG with supporting mods and Precision AP Pro Tune. My question is yesterday after changing my oil I went for a ride and notice that at idle my long term fuel trims were around +5 when they are normally -1 or -2 never positive. Any help would be appreciated.

You're fine.
LTFT should be +/- 6%. Anything above 8% you should be looking for different mapping style or ProTune. Anything above 10% I recommend not boosting the car. The LTFT can jump 1-2% just by bad gas alone. Cheers |
