Does anybody have any experience running a catless downpipe with an O2 simulator to hide the enige check error?

And I have read some topics about issues with fuel when you having a O2, is this true?

Thanks!

These BMWs do not typically respond well to sensor specific tricks of any kind. Your best (and only option in my opinion) is software programmed specifically for eliminating the CEL.

I am using http://www.bigdaddiesgarage.com/mini-cat-cel-fix.html until I get a tune.

There is another post if you search that has mixed reviews. Mine it still going strong!

I bought this mini cat and it didnt work for me at all. CEL came back on right away.


currently using JB4 to eliminate secondary 02 cel.

So it's not really a fix like the say...

I'm going for a ECU tune anyway, but I just have the M2 for two months and I think it's to early to get the extra HP and nm. I would like to drive it for a year and then having that extra power..

There's a company in Canada that offers a simulator that they claim to work on everything. It auto corrects unlike other versions that you need to find the sweet spot on by manually adjusting the setting. Running Fabspeed 200 cell downpipe, no CEL, (knock on wood).

Tried their O2 simulator and it's garbage. My car ran so bad it felt unsafe to drive and threw a bunch of codes. I installed it to the precise recommendation (which was funky to begin with) then uninstalled and reinstalled per their "technical support" in the end I got sick of the crap. Yanked it out and got the Fabspeed. No issues now...

A good tuner should be able to delete the 2nd o2 sensor

I didn't try, but it would work well:
