UPREV Tuned can't pass EMISSIONS

TPrelude-370z

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.

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.
