ok in the future i want to do a block back exhaust and was curious if i remove the cat will it throw a CEL due to the post cat 02 if so how do i stop it. is there an 02 cheater or chip tuning for it or what?

The mid-cat sensor will (usually) throw a CEL if removed.

The usual O2 fooler circuits don't work - the ECU changes the mixture in a sequence, and if the secondary sensor does not respond in the same sequence, it's a code.

You can take your O2 sensor and plug it into whatever you plan on using (I have a midpipe) and you'll get a 50/50 chance of throwing CELs. Like Stealth, the O2 foolers don't work in the 8.

 

damn those things does anyone make like mail order chips that clean up the tune and delete that thing?

 

no

 

So....resorted to one word posts to catch up with mikeb, have we??!!

 

i gave him the simplest answer to his question. the longer version would include info i am not ready to talk about yet but would also not get him any way to turn of the o2 censor.

 

In light of the current "Postgate" fiasco, I took the opportunity to joke with you Charlie.....I'm just kiddin' :p
