I thought that too, but we completely disabled it by setting the tpsdot threshold to like 500%. My tuner thought it was either FPR or my E85 isn't E85 but maybe less making it richer, but I've measured it and it's E85 on the money. And as far as AFR control, it's very minimum under boost. 10% I believe is what we have it set at to force it to honor what's commanded in the VE table and not try to adjust to meet the AFR targets. It seems that turning down my base fuel pressure might work, but that will throw the whole tune off, so don't want to go that route. Thanks!
