To make the open loop part of the maf scale match what it's supposed to do at WOT I have to pull ~12% fuel in that rich spot, which means I get tip in knock correction of -1* or so and STFTs of +10-15% from 2.7v+ while in CL. I get a VERY nice smooth curve everywhere else, about -3% off the rest of the way up the revs at WOT.

CL maf scaling is a piece of cake, and OL would be fine except for the weird rich dip I get when WOT.
