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

any one figure this out yet??? just picked up a 01 gtp and want cat gone..

Rumor has it that there is a version of TinyTuner floating around out there that can disable the cat diagnostics in some OS's. I have yet to find this version but I've heard some people talking about it. Keep in mind this feature isn't available in all OS's TinyTuner supports; and as there are many OS's available for any given make and model year of V6 car, it is likely your OS doesn't have this feature supported (in the TinyTuner software).

So, what I would recommend you do is just use 2000 model year programming in your PCM. I know several people have done this and haven't had any issues so it would probably be the best thing to do for now. The cat diagnostic issues didn't show up until 2001-newer V6 programming; so 2000 model year shouldn't have it enabled.
