Removing rear O2 sensor on 01-newer PCMs -- Things you should know

[FoSHO99]

I need a solution for this also... I have a powrtuner and 3 cars that are 01+, 2 surge at idle right now and my ltft's are inconsistent.

same problem here, hope someone can figure this out! myself and DanGTP are trying to tune my 05 GP with a catless DP using HPTuner and the LTFTs are way up there. Getting a lotta KR in the mid range RPMs too...i guess asking OverkillWill how he overcame this issue would defeat his purpose of selling custom-tuned PCMs?

I have a 2001 with no cat or rear o2 sensor. My ltft's seem to be pretty close to 0 and my wideband fluctuates around 14.5 - 15. I guess I'm a lucky one?
