    I've got my trims down pretty good. Actually kinda happy about that. Cells 2 and 4 are right where they should be, which is good for my trip I'm going on next week. What has me concerned is PE mode.

    For some reason, its totally FUBAR'd. I thought it was my tune being off, and that maybe my PE was a little off, but PE just sucks. With my VE tuning file, I have PE set to enable at 100% TPS so its pretty much disabled. I got only a flash here and there of a half a degree of knock all the way up to 55% TPS.

    Once I got done tuning, I set PE back to enable at 30% and as soon as PE enables I get like 6-10* of knock and it stays.

    My O2s when that happened were around 920-ish I think (wasn't recording at first). I stopped, looked at the Base_PE_AF table and my AFR at the time this was happeneing was in the low 11s... Probably way too damn rich. So, I put the AFR to 13 for all the areas I would need it and went again. Same thing, except now my O2s are around 898. Too lean, I guess.

    The car ran great without PE, but I can't get it right. Where should my O2s be? And anything else I can be adjusting? As it is right now, PE is way off.

    Remember, I have a L36, not an L67. Attached are my PE tables...
