Ok so basically I scan it by rolling into the throttle on up to 100 kpa. Save the scan. Then how do I re sort the scan to maf hz? So are my trims always gonna lock in 0 all the time or they gonna adjust themselves again? My STFT locks at 0 but my LTFT is at 3.1 now. When I'm off the gas or idling, my LTFTs read 16.4. I know there is no vac leaks cause I've sprayed everywhere. The guy that tuned it said that's normal with e85. Is that true? Another guy replied to this thread on clubgp said its normal for the trims to read between -/+ 3 for compensation of fuel, is that true as well? I'm just confused because I'm being told mixed things.
