uprev and emissions

[jamesj1996]

so i was reading a thread on uprev and emissions...so apparently this guy failed with uprev tune and what not? anybody know anything about this . im getting one soon but im in jersey and i needa pass emissions. theres a stock map isnt there. im confused on the thread nd need someone to explain this to me bc i need to pass emissions didnt think a tune could hurt.

[jamesj1996]

anyone???

It depends -- how do they do the test in Jersey and what other mods did the guy have -- most people don't get a tune with all stock breather parts.

It could have failed on visual inspection with intakes, for example, or the person might have had non-OEM cats (or none) and failed either visual or emission output, which will not be improved from the tune.

If everything was stock and he failed, then flash it back to stock before inspection and re-flash the tune on there after.

If the issue was mechanical/actual emissions produced, and NOT just due to the tune, then it all depends on the mods and where you get tested -- good luck.

hfc exhaust and intakes is wat i have

Some states fail you if the downstream O2 sensors are turned off or are showing not ready. Some don't care. Might be worth posting in your regional subforum for the specifics in your state.

If the post-cat O2 DTC is turned off, that might be picked up from the OBDII port like Chuck said.

In your case it is possible that the intakes fail visual or the HFC's don't pass smog. Best bet is to simply have the ECU put back to stock temporarily or at least make sure all your DTC codes are ready (i.e., not turned off in the uprev menu).

ok true. i passed with hfc and intakes both visual and obd but i think that if i go back to stock map ill be good

I've passed w/ uprev, art pipes, stillens and fi cbe. All my monitors were on and ready. Invest in a code reader and be ready when you go.

edit: just realized you said "visual". That's a tough one.

so basically tell the tuner to make sure all DTC is activated and codes are turned on then emissions wise i should be good? or i could just tell him to have them on for the stock map and select the stock map before inspections

yeah exactly but with high flow cats i already passed once with them visuals and OBDII so that shouldnt be an issue...did u just go back to stock map when going through emissions

also did u have to tell ur tuner to keep all DTC monitors on ? i know that DTC can be shut off causing the OBDII port at DMV to say "not supported" or "not ready"

If you passed before with HFC and intakes, unless they're doing something new since last inspection, it's gotta be the DTC monitors.

Have them all on for the inspection and you should be gtg
