LTFT fluctuation?
I have seen a few threads about LTFT. But my question is can it help determine AFR if you are lean or rich and what is the acceptable LTFT on an evo x I have been anywhere from 0 to 3.9% is my ecu still learning or does it change that much from day to day?

Thanks for the reply I meant to be in the x management/ forum area if a moderator could move my post that would be great. I did see the +- 5% is ok so you confirmed my research. It seems that LTFT should be less variable but who am I to say how a tune should be im a novice. ive seen + 3.9 to 0 in one non wot trip seems like the ecu is always learning as apposed to learning and running with it.
