Default TE tune with O2 on or off?

So I was doing some fine tuning on the afrs in vac with the O2 off and was getting some good numbers 14.6-15.5, so I thought ok now I will turn the O2 on and it will do some smoothing out of its own and It will be ****. WRONG, one I turned the O2 in in the general options, my afrs went to ---- like 12.0-13.3!!! WTF happened? I dont get it. SO ---- it im running with the O2 off. What is the pros and cons of doing this?

thats why i love my aem WB it has a signal wire that you hook to the ecu to make it think you are running a stock o2.. and have never had a o2 code in TE

the thing is that i get no cel because the O2 is turned off. I select it to off in boost, and the afrs go way rich. Idk whats up with that but im getting 33-35 mpg on the hwy now with the O2 off.

W/ TE, I like to leave the o2 enabled. Unplug the o2, get the car up to temp, and do a long (8-10sec) decel in gear to trigger the o2 CEL. This way, you know for sure there is no closed loop action going on. Clean up you maps, and plug in o2 if you so desire.

This is assuming your TPS is not misadjusted, and the car is going into decel fuel cut when you try and force the O2 CEL.

Good Luck w/ it.
