What map controls the O2 learning?
That sounds right. But isn't that intended functionality? As in, the LTFT will correct any errors in fueling caused by MAF errors for example. If you remove that functionality then you allowing the error to go uncorrected. I must be missing something...

In EcuTek the map is called "AF Correction #3 Limit - Rear O2 Learning"

Thanks for your help! :-)
