So I'd like a little clarification here. I know that OEM's go open loop at WOT
and end up running rich (my Toyota P/U accelerates faster if you go WOT and
then back off just a touch), but I don't know why. I can't see any danger
running at stochiometric at WOT (but I can sure see why you don't want to go
lean). I always assumed that manufacturers went open loop to run richer (more
power) at WOT. Anyone know for sure?
