Closed loop is using o2 feedback to make the AFR more rich or more lean. If it's consistently lean or rich, this will turn into a long term fuel trim adjustment.

If it's only running like crap in closed loop, take a look at the long and short term fuel trim and o2 volts, maybe your sensor is going out. Did you say you have a wideband simulating a narrowband?

I dont have my laptop with me but memory serves me yes its using the "wideband simulating narrowband" I believe that box is checked.
And which ever loop it is. The one when you go wot.... itll stay in that loop for ever. Last night ot stayed in the loop for probably 5min of normal cruising after I did a light pull. And actually it would go back into the wot loop even if I was still cruising.

I posted that whole log from startup till I got home on ecmlink. Its my last post on that thread.
