Is there a way to turn off the post 02 on my ‘05 MCS?

 

Yes..I had mine tuned out

 

I'll never understand why people on here struggle so much with O2 sensors and cats.

 

How?

 

Well then tell me what's the secret?

 

via tune... pm adriancl , he can give you the exact answers you need. He tuned mine for me.

 

A proper cat.

 

Or, you know, move...

 

We don't have emissions testing here, hell, not even vehicle inspections unless a cop send you get one, yet I'd never run a catless car. But hey, a lot of people seems to be running track cars on the street pushing mad power requiring to gut the cat.

 

Or Karen report-f**ks you to The Authorities...

Same clown world here in the DPRC, plus the "CARB-approved" cat racket industry of course...

 

 

I'm going to go out on a limb and say that most folks don't want a CEL for something that does zero to affect how the car performs (down-stream O2).

On principle, I would prefer to have them deleted on every vehicle I own. A failing cat is easy as **** for someone with a couple brain cells to figure out, but people are stupid, so we enthusiasts get to un-**** the stupid rules set forth by the Fed to corral the aforementioned dummies.

So yeah, changing a 1 to a 0 so that someone may do as they please is for sure the best course of action here.

 

I don’t have to no inspection here and I’m using the Miltek cat which is a high quality cat.

 

What do you mean by changing a 1 to a 0?

 

I'm one of those people that HATE seeing my cel on. If it's on I want it to come and lmk when something else is going wrong..

 

yes same here.

 

"Changing a 1 to a 0" is saying that a digital method trumps physical methods, when the digital method leaves no trail of inappropriate modifications (cut wires, de-pinning harnesses if the car would ever be sold, just slapping some tape on there like a nonce, etc).
