Long story short, failed state inspection, removing Art pipes for stock. If I switch to stock uprev map, is the ROM still considered flashed, I.e. is it a different serial number vs. stock? Massachusetts now detects flashed roms and flags cars which happened last year.

I can remove the tune all together if need be, but is there a way I can tell if I send someone my maps?

Thanks,

i would buy a stock ecu, throw it in when time for inspection

 

Well, I just flashed it back to stock. Took a few mins. Just a pain in the butt to swap out the cats. Anyone know how long before it will throw a code Untuned with ART pipes?


Would it pass with Art pipes and exhaust no tune?

 

^i know here in cali you will not pass without cats. Most people dont pass even with HFC's

 

Yeah, It will definately throw a catalyst monitor code, but I think it requires at least two codes for failure in MA.

 

I have motordyne tdx v2 aem cai and hfcs and i just passed smog, the stock tune should get you to pass aslong as all the original settings remain the same like timing

 

What did you end up doing?
How does your local emissions testing work? Does it hook up to the OBD2 Port? or is it run on a dyno at 2500 rpm and idle?
I am going through a similar thing with my Z also.

 

I returned to stock rom and swapped to oem cats. Rinse repeat each year since failing

 

Testing is done usually by visual and obd II port. Once it is connected all of prior years info comes up. So in my case I passed two years with HFC's and the readiness monitors were bypassed. On year three I failed.

I was told by the state inspection center that any time a rom is flashed the serial number changes from stock. That is how they detect tampering, also you can have no more than 2 or 3 readiness monitors unsupported or N/A in Massachusetts.

 

What year is your car ?

 

Not sure who you are asking, mine is 03.

 

You can pass with a UPREV tune so long as the DTCs associated with OBD readiness have not been disabled...

 

They were bypassed.
