O2 Sensor question

http://www.americanmuscle.com/kooks-...509manual.html

I was looking at getting these at some point, with no cats won't you get some kind of dash light. Can anyone shed light on this?

One trick is to get some spark plug non fowlers. These fit over the O2 sensor and allow the computer to read less fumes. You would install them where the sensors after the cats would normally work. I did this when I got high flow cats and it worked flawlessly. I don't know if it would work that well with no cats, but it is a cheap fix. Worth a shot.

Technically that MIGHT work to prevent a code from being thrown, but the 11+ models also have a COT feature that you also have to deal with. So even if you use this method, the car would still be dumping gas into the would be cats trying to cool them down. Hence the reason they dont make mil eliminators or o2 sims for our cars. Without a tune, the car will not run correctly. And you wont see any gain in HP.

This is the first I've heard of the COT feature. What exactly is it? My bama tunes have worked wonderfully while I've had the non-fowlers installed.

It stands for Catalytic Over Temp feature. What it does is it prevents the cats from over heating by dumping fuel into them to cool them down. By just adding fowlers, you will fool the o2s, but the COT feature will still be enabled, and will continue to dump fuel. With a tune, not only does it fix the o2 sensors but is ALSO disables the COT feature.

Maybe it's different since I still have cats with my kooks mid-pipe. So it would not affect me. After reading over your post again, I think I understand what you are saying about if there were no cats. The non-fowlers would make the engine think there are cats, but there would not be. That is a good observation. Thank you.

Got it. I learned something new today.

If you still have cats, you're fine. And should continue to use the COT feature. You only want it disabled when you run with NO cats.

Glad I could help!
