What is the MAF frequency at idle? (FO on the LCD)

FO on the LCD when the problem is occuring sits at 23-24. I think this is because the unit is trying to remove all fuel possible (CF = -10.3) when the AFS readings are 10.3.
FO on the LCD when the problem is NOT occuring is roughly 30.
I think the low FO during the rich idle is an after-effect, not a cause (the unit trying to offset the rich mixture).
Also, my trims should all be 0 b/c the stock O2s are unplugged.. should i hook up my other datalogger to verify this?
I can try resetting my ECU and increasing the idle speed if you think that will help also.
