LS1 edit WOT tuning? I went and got my car dynoed and had the air/fuel checked too. I know on ls1 edit you go to PE vs. RPM, but I was wondering if there is some trick to it. For example, the first time without any A/F tuning it was at an average of 11.6. I didn't take my ls1edit out there so I used my MAFT and adjusted it to 6% lean and it jumped to an average of 12.2. The problem is, the A/F right now is very wild (in the fact that it will increase, decrease, increase and decrease by .5 or a more over a couple 100 RPMs). For example, at 4000 it was at 11.8 and by 4750 it was at 12.8. I've seen that you can adjust at certain RPM, I was just curious to how much I should adjust it. I figured I would start by multiplying the table by 94% (since I adjusted the MAFT 6%) and go from there. Basically what I'm trying to get at, is there a certain percent or number (say 1%) that will cause an X amount (say .05) of increase/decrease in the A/F ratio?

Re: LS1 edit WOT tuning? With my car, one percentage point adjustment in the PE vs RPM table yields approximately a two tenths a/f change. So if your a/f is 11.6 and you multiply the table by 95 percent, that will put you at approximately 12.6 percent a/f ratio (.5 x 2 = 1).
