Here is the question... Who here knows about SCT tuners that have custom tunes that can shut off the rear O2 sensors?

I have an SCT SF3 with a custom tune that was supposed to shut off my rear O2 sensors on my off road H pipe, but for some reason I keep getting a check engine light for the O2 sensors (P0430).

I also have MIL eliminators which I took off thinking that my custom tune would do the job... but it didn't work!

I just don't get it! Why won't my SCT tuner work!!! I have talked with SCT and the place I bought it from, but still no answer.
Please help!

Thanks!

Not sure about SCT part of the issue - I dont own a tuner. But a question for DB, do you recommend catted option for emission reasons or other? Just curious, thanks

yeah mainly. i mean i just bought my car with the o/r version and really i doubt it does a whole lot for a dd to not have the cats, so its easier for emission testing and all that hassle (damn tree huggers) and really even with MIL eliminators i seem to be having part problems due to the no cats thing. plus a mental thing for me, is since its not a strict track car, the lack of back pressure seems that im losing low end torque. again, that last bit is just my crazy mind but i do believe there to be a sliver of truth per other threads out there. overall its really just the hassle of having the o/r x are not worth the hp/torque gains (if any) over a high flow catted one. im about to get some high flows put on it.

I see your point. I have always heard that the right amount of back pressure (not too restrictive & and not too open).

Does anyone use MIL eliminators to shut off the rear O2 sensors instead of using a tune?
