How do you adjust the PE vs RPM table? I've adjusted my Ltrims to -4.6% since I'm running a port MAF. Now at w.o.t. my 02's show to be .71 from my autotap runs.

At what rpm do you start adjusting and how much do you change the numbers?

Thanks

 

.71 is really lean; I wonder how accurate that is, especially if you richened the MAF table to compensate for the ported MAF. Do you get a lot of KR or low timing? If not, I doubt you are as lean as it appears.

You need to look at your o2s starting around 3000 rpm and see how run. Add .2 to the needed rpm range and retest. I would do it on a dyno or at the track rather then relying solely on ATAP.
