So i read that ppl can make the check engine light go off with the cobb for when they have a mid-pipe installed. but i was wondering if it turns it off completely or just makes it disregard the o2 sensor?

not really sure if this is the right spot for this...but it is interior electronics. lol.

 

you have to purchase it thru mazdamaniac, he will mask the light....if you don't buy it thru him, all you can do is reset the code, but it will come back

there is a lot more the ap is good for...not just for hiding the CEL...I suggest you do some reading on it.

 

well yeah i know thats not all its good for. but i was debating on getting a midpipe cuz the cel drives me crazy. but now. i will. thanks.
