Pretty well ignore stft.


Ltft is average of stft over time period, its measured in several flow bands.


Fuel trims dobt mean you car is running rich or lean, fuel trim is the amount of correction the ecu is applying to attempt to hit its afr target at a load rpm range.


If you want to know if your rich or lean look at AFR and commanded afr


As your on E85 without flex senspr differing ethanol contents will see ltft change as ecu alters this to hit its fuel targets
