Emissions Testing

[mkPOTO]

anyone in Chicago pass emissions without cats?

[Jaymax85]

It would be tough because no tunes openly advertise setting obd readiness.

[gazosnic]

interested to hear as well

Illinois uses just an OBD read correct?(per their website) So shouldn't a typical tune that resets your CEL should suffice? That's my plan in WI(I'm running catless too) and that's what I've done on past cars.

[gazosnic]

tune would have to keep sensors reading ready status as well

No, because to pass you need to set exhaust catalytic cycle readiness. Not just turn off the cel.

I have read on this forum in the past that people have passed readiness inspections with the tune. Just visual and sniffer tests are what would cause you to fail.

I believe that is correct... there are a few tunes that keep readiness intact apparently. I personally do not want a tune so I am very interested in those who can pass w o2 spacers / mini cats. I plan to maybe just go the test pipe route, but still want to pass emissions.

if you go the test pipe route you can aways save the cats and bolt them back up

Yea will save them... from what i heard its not easy to bolt back up due to the angle where you need to cut... need to be welded back in... but i may be mistaken.

I got a stock x pipe, if u Just want to borrow it, and drive like 80 miles before go get the Emissions Test.

Nick, I have a stock x pipe for sale if you want to have one to swap. Cats still intact, I swapped it for a cat less race x pipe.

how much?

[IzzyGray]

There's someone wanting me to hold it for $250 so if you're ok with that, I'd just let it go.

What tunes preserve readiness? This is the only thing holding me back from a test pipe and tune

Pretty sure ESS and the other big name ones keep it working.

BMS tune? was this on a 335 or an m3? I never knew BMS makes a tune for the m3...
