I'm waiting for my LC-1 to get here so need to use fuel trims to do a quick tune cause the truck is running like crap, probably really, really lean. I followed the word documnet how to use stft to tune but there are 2 steps in there I cannot find, when you set PE enable to 640 what is that? and how to set ltft to off how do you do that? On it's efi live. I already did the autove tutorial so hope I did it right so i'll be tuning in OLSD Thanks guys/gals. On and it says reference the stft histogram, what is that? and one more thing when it says paste-special add to ve table what does that mean?
