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

Then if your still kean look through the coloured links below |
Ahhh I see thank you, And so range of AFR’s that are running too lean is higher then the targeted range and if it’s rich the. It’s less then the targeted range? Sorry I’m just trying learn a little bit here. Also do I shouldn’t be worried about my LTFT and STFT Going above 10% at times when I normal drive to mid range? I have a k&N drop in filter but idk if I would have to rescale that and maybe that’s why my fuel trims are kinda high at times?
