UPREV Tuned can't pass EMISSIONS
 

Hey guys,

Before giving me crap about searching, hear me out. I have researched and mostly you just run into arguments on threads. Basically I have test pipes and custom exhaust, stillen intakes, and UPREV tuned. I failed IL emissions because the Cat readiness codes give them the "not supported" instead of ready. I believe uprev did leave me with a stock tune but I do not remember which map it was for sure. Not to bash them but UPREV has very poor customer service. You cannot get them on the phone ever and they do not respond to emails either. I need some guidance please. Thanks

I'm not familiar with the tune, but the first thing I notice was the test pipes, I was just told by a vendor here that test pipes will not pass emission.

Map 5 is stock.

You probably have to at the very least put the stock cats back on. The stock intakes as well if you can.

Sounds like you have the DTCs disabled. About a month ago they changed it so that cars will not pass the test with systems "not supported" when they know the car has the system. Last month I passed with evap and o2s all disabled and "not supported" but heard they changed it like right after I passed.

Go into uprev and activate all your DTCs. With just intake, exhaust, and test pipes, you don't need disabled DTCs anyway. My 09 never gave codes for the test pipes. If yours does, get a set of those spark plug spacers people use to avoid that?

i just got inspection/emissions monday and i passed with test pipes and tune.

only time i ever had a problem was the one place put my car on a lift and actually saw i had no cats then failed it.

but without them seeing the cat delete my car passes everything.

BTW guys my post above is referencing to the state of Illinois.

Every state is different about if they will pass a car with known applicable readiness checks "not supported" after being disabled in the ecu. Illinois did pass that 3-5 weeks ago, but changed it so they no longer will.

In Illinois there is no actual inspection, just an OBD test. You have to have all readiness tests test OK and no DTCs that would in any way effect the engine.

If you live far enough from Chicago, seems about 100 miles each direction, then they don't have any test at all for you. My 350z was always registered to my grandmothers address out in the middle of no where to avoid testing. It had a standalone and no uprev as available back when I did that.

thanks guys for all the responses. Do any of the illinois guys know of a "Friendly" testing site that I could offer up some cash to pass? PM me if you know someone.

Now that I know its map 5 I will try the stock map, thank you for that. How long do I need to drive around after switching to that map before all the systems are ready? I hear you have to let the computer cycle a bit.

I didn't have any cel codes when I went testing. It must be the map they used disables the readiness codes. I hope its that easy. I would need to buy the stock cats as I no longer have them. I would rather not go through all that crap of reinstalling and removing reinstalling again in order to possibly pass. Knowing after all that, I might have the same issue with the uprev tune. Thanks again guys.

I THINK the cycles are like 3-5 on offs. And maybe 50 miles?

Can you pay $20 for a pretest like here in CA, it doesn't give you a real fail and send results to the state, then the $40-50 if it passes the pretest

There is no way to bribe out of it, its 100% done by the computer systems. All the testing sites do is plug in the cable, then print you out a piece of paper, and send you on your way.

All you have to do is reactivate your DTCs. There is no need to put cats back on the car or anything like that. You just have to have all your DTCs activated so that your system readiness tests can process.

Because your fail was due to NOT SUPPORTED, this means its pretty much a definite thing. NOT SUPPORTED means it was disabled.

thats why i love my FI exhaust. passes all the cpu tests. only way to see its illegal is to literally see that i have no cats lol

I don't know... Lol
CA, is KNOWN for the toughest emissions, and we've got guys you can pay, lol

my one show truck that i drove a bit had to go to a "special" place to get inspection/emission stickers lol :stirthepot:

i think you would be looking at a lot of work and expense to do that with a 370z here. anything is possible, but of course it has to be within reason to bother.

It's $150-250 depending on who you know
Vs $45-50 for regular

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.

Free?!?!?! WTF??? Is it done inside a gov't building?

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 :icon14:

When you buy the car, on the 6th year and every 2 years thereafter

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.

Passing without cats is a Testee win and a Tester fail.

Yeah I was close

Sent from my Palm Pilot circa 1997...

Lol, it's ok, you get a free pass because of your Palm Pilot circa 1997

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! :tiphat:

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
