I'm running the same MAP (also called the MAF Transfer curve) that runs correctly in open loop which is why I feel that there is something in the closed loop part of the program that's forcing the system to report very rich conditions. I tested a much leaner version of the MAP and, even though the numbers were still showing a rich condition, I experienced significant lean running indications.
I'm hoping to chase some thoughts down over the next couple of weeks although the weather and painting the inside of the house are going to slow me down a bit.
