UPREV Tuned can't pass EMISSIONS

phunk

emissions testing is free in Illinois.

I do not think that 250$ would even come close to taking care of a fake pass here in Illinois, with a 370z.

I am sure we pay for it somewhere... but its not when we go to get the test.. its probably including in the yearly registration fees

OP, switching maps will not re-enable your DTC codes. It will only switch your fuel, ignition, and timing back to factory settings. You will still fail as the 02's will still not show up.

So I got lucky and spoke with UPREV. Basically I would need to actually reflash the ecu to stock, drive it around for 75-100 miles, then pass the test, then reflash it back. Not super expensive, just a pain in the butt. The shop mentioned Il just changed this law about 2 months ago and he has got like 5 other guys with the same issue.

Shop will charge 40-80 to reflash depending on if the stock map uprev sends them is ok. So figure paying that again to reflash it back as well. I also will prob have to get some defoulers installed by them since I don't want to drive around 50 miles and have the cel light come on and repeat the process over again. All in all with defoulers and re-reflash I'm prob looking at 200. I am cool with that. Thanks for all the help guys.

good call chris, I just found all that out. Glad I didn't quit calling.

why dont you just ask them to reactivate your DTCs on your existing map? This would solve your problem, and keep your tune you already have. Then you wouldnt have to go back and flash again after emissions. Its like a 30 second process.

its well worth the cost if you are FI here in CA. CA has a visual inspection as well as a sniffer. Generally most well tuned FI cars can pass the sniffer but you need to get them to sign off on the visual. We only need to be inspected every 2 years so an investment that i would happily pay.

I can see that for your state, especially with forced induction, if its only $250.

I was just talking about here in Illinois... I do not think you will find anyone that will fake pass it, especially for only $250.

Illinois has no visual inspection or sniffer, and only even checks vehicles registered near the city of Chicago. So there are much easier ways around it.

its been awhile since i have done a SMOG here in CA since you have 4 years from the purchase date to SMOG but i believe they do hook up to the car to get the timing and other info. The visual and sniffer are the big issues here in CA

I wish I 'knew a guy' in Maryland but inspections are run by the state - as in "state inspection stations run by the government" you have to visit every two years.
