I recently got the code on my car about the o2 sensors because I have catless exhaust. What is the best way to fix that ? I was told that these o2 simulators should work but i am not sure. http://www.o2simulator.com/index.php...&reviews_id=30.

I have jb4, intake exhaust, dp, cp, bov, and intercooler.



Thanks

Just set your JB4 to "auto clear codes"
You'll get rid of the light, but you won't pass emissions...you'll get a not ready status.

You can buy a dp fix from BMS as well. I have tried and tried to build O2 sims for BMWs...I can't It's not a Ford or GM.

What other codes do you have when you go into limp mode? Having cat-less downpipes, and the resulting O2 codes will not cause limp mode. There is something else going on that you will have to diagnose. Most likely plugs, coils or injectors.
