having the o2s turned off in the tune wont let the car pass inspection. it wont set all the readiness monitors. i had to have mine turned back on. after that the light would come on every 100 miles or so. i bumped the timing 2 degrees and its stayed off since. :idk:
yes you can turn off the rear o2's and it will pass inspection. but it has to be done in the tune. you shouldve just saved the hassle and had the tuner recheck the tune. they didnt do it right. i seen it happen before, i have a feeling i know who tuned it for you
