What's weird is that the LTFT seems to want to go positive, but if you subtract the amount of stft it's actually not that far off. It seems the afr will fluctuate pretty drastically under certain circumstances and somehow cause the ltft to go positive. While with ltft positive beyond a couple percent or so the stft will be just about the same amount negative canceling out the positive ltft. But once you go into OL operation the ltft just sticks at the positive trim causing it to run rich. Does that make sense? Lol

I think this is what I'll have to do. Since the previous di/pi ratio table I had it set to fully Di in the first 3 columns (.10, .20, .30 load) Whereas the new table has it set to 70% PI from .20~.40 at low rpms. This is the area I'm getting the most trouble I think.
