Re: PEvsRPM table need it for the ATI SC!!!! how do you know you are running lean?
i don't think anyone will be able to tell you exactly what numbers to put in there, there are alot of factors that determin where to put those numbers. if you know for sure that you are lean during certain rpms just up the numbers a little fo those rpm's and try it again. i have been multiplying the numbers by 95% or 105% and then loging to see how it worked, then do it again if you need to.
it is ok for those numbers to be the same, mine actualy peek around 4800 and then fall off from there.

Re: PEvsRPM table need it for the ATI SC!!!! if i multiply for 105 is going to be rich or lane????i saw lane at wot on my gauge!! <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
Re: PEvsRPM table need it for the ATI SC!!!! do you have atap?
what kind of gauge are you talking about? is it just the basic a/f gauge that hooks to your factory 02 sensor wiring?
if you have one of those basic gauges it should jump from rich to lean quickly most of the time and then go to far rich when you floor it. if it is going lean you have a prety big problem. you can't really tune with one of those but it shouldn't be lean.
to add fuel with the PE vs rpm you would want to multiply the chart by 105% that would add 5% fuel. i am no expert on the subject but i would suspect the injectors are too small or your fuel presure isn't holding before that PE chart.
tell me if you have atap, if you do i will tell you what i log and you can go and do a log and then send it to me. you need to do things like check your fuel presure at wot and check you injector duty cycle.
good luck
