So... How do you pass? Or is there no visual, and you slap your stock cats on every 2 years?

No visual (that I remember). I have hi-flow cats on the car not test pipes. That was my point. I'd rather run straight pipes.
Edit: Also, my car isn't two years old yet.

It's not all about the DTC's being disabled. It has to do with the states computer identifying the ROM has been flashed which results in failure. Massachusetts recently implemented the same measures and I went through this already. Have to flash back to stock.

I can't believe they would spend so much energy to try and crack down on the very few and small percentage of drivers who change their ecu roms! What a waste of resources.

Welcome to the gorvernment, good to have you here!

Mother-F... I'm thinking about moving to MD or AZ. Both states have vehicle inspections. One of the few upsides here in Michigan is that there are no vehicle inspections. Heck, I bet I could get away with running headers and test pipes W/O an exhaust.

Uprev tuner disabled the DTCs die to not having cats, otherwise DTCs would go off.

Once the stock tune is returned, DTCs will be set due to O2 senors reading high due to no cats, failing again.

The only fix is to reinstall the cats, and the stock tune.

Since when does AZ have emissions testing? MD does and it is not that bad. If you have stored codes, they will dig deeper. Otherwise, you should be good to go.

who needs a fix when you can use a band aid.

two tunes identical, one with dtcs on and one with them off. when you have to test, flash to the ones with them in the ready position. drive 100 miles and test before they turn on. pass test, flash back to the other tune with them off

Either way the ROM will still be flashed and cause a failure.

That's not a bad idea, but most people here use a tuner and don't own a cipher cable.

I'm going in 2 months and I know others w/ uprev that have passed. We'll find out soon enough. I'll be more than prepared.

I'm curious to know how it goes for you.

Are you talking in the state of MA.? When particularly?

mag_black · 02-09-2014, 07:35 PM

^^ yes, in MA. I have it due at the end of April. I believe Tibal is getting his inspection soon too.
