Little lost on what to do so i’m hoping this forum could help.
My 230i (f22) isn’t passing emissions in NYS.
It’s showing CAT, EVA, HTR in monitor status.
As well as the codes Catalyst System Efficiency Below Threshold (Bank 1) & Lost Communication With ECM/PCM. I’ve done the whole driving X amount of miles under 60mph, no luck.

I also have absolutely no luck finding o2 sensor spacers since that seems to be the issue, so if someone could guide me in that direction it’ll be very appreciated
!
Car is tuned, fbo.
Just asking if there’s another solution to have the car monitors ready for inspection rather than throwing the catted down pipe back on (car is also on stock map now).
NYS is annoying!!!

The car IS NOT GOING TO PASS IN NY with a tune on it. It's as simple as that. Flash and convert back to stock. O2 spacers ALSO FAIL INSPECTION.

you can also try getting spark plug anti fouler and fill it with coarse steel wool. it can trick the ecu into running normal sometimes

LA1Z24 I failed to mention the codes & readiness were after i flashed the car back to stock, and after i did the whole “drive 60 miles under 60mph” thing. My question was if there’s a way to help clear these with my catless downpipe still installed or do i have to go back to my stock catted downpipe.

Yes, if you don’t have a cat, the car will throw a cat under efficiency code. The emissions system is essentially designed to prevent what you are doing.
