Ok so I had my ve tables close and was fairly disappointed in motor but turned pe on and it perked up a lot. I adjusted pe afr multiplier vs. rpm, 1.03 to 1.05 and that was fantastic, took ae down a tad at high rpm, that cleaned up the take off feel and sound. Now the problem is I have a rich area 2000-2200 rpm x 40-60 kpa and a lean area 2400-6200 rpm x 80-100 Kpa. Lower rpm in 80-100 kpa all at 122!?!?!
I tried advancing timing in about 4 cells to try and lean out lower rpm area but I did not see a change. Maybe I did not add enough?!?! So I went back to pe multiplier, up or down only leans out upper rpm and ae doesn't seem to effect Blm history.
Did I miss something or not aggressive enough with timing?
