For people who have deleted the cats from the exhaust, have you used O2 sensor simulators to stop the CEL from popping up or just put up with the CEL?



Thanks,
Tim

 

I had purchased O2 simulators but I was getting codes. I removed the sims and have been good since. I am running AAM test pipes that already have the spacers for the O2 sensors.

The HR is known to be very finicky with O2 sensors.

 

just get it tuned

 

Or get test pipes with extended O2 bungs, like these...

 

Or electrical tape over the light if you are really cheap. Lol

 

I'm pretty sure you can't turn the o2 sensors off anymore in uprev Osiris, which is the most common tuning solution for folks staying n/a.

 

yeah well then it sucks to be him

 

...lol

 

that didn't work for me. I got the megan racing onea and still got codes

 

What codes? Downstream or upstream?

 

When I deleted my cats I never got a CEL or a tune. 03 350z

 

I get them every 3 cycles or around 50 miles....both sensors. I have OBD reader and an iPod installed...I just turn it of until full exhaust is done and the tune to solve it

 

I used Berk test pipes. They have the "built-in" spacer. The CEL comes on every 8k miles or so. I clear it with Torque App and it doesn't bother me for a few more months.
