Some of what you saying does not make total sense. If your AFR's in OLMAF were good, then going back to CL would have

What I am seeing is that you are incredibly rich in your entire Tune. It is throwing off your
CALC VE Table to a great degree.
Have you thought of doing the
CALC.VET instead..

Even if you go back to OLMAF you will incredibly rich at WOT..Not sure what happened, but it has nothing to do with closed-loop at WOT..
