Be Careful with UpRev in Mass

haha, what's the argument here? I passed w/ sensors on and uprev, he failed w/ uprev and not knowing if sensors were disabled. I have hard data, he doesn't know

I know plenty of people that pass w/ uprev and headers/test pipes. People that failed here, have no idea about their tune. That's the variable here.

No your just intentionally ignorant to the facts. If you try to pass with sensors disabled you will fail every time. If they all show ready you will pass every time just like the rest of us who do every year. This thread should be deleted.

Invest in an OBDII scanner. I use PLX kiwi wifi 2 and DashCommand.

edit: I hardly get "cat inefficiency", but it does show up from time to time. It's not a stored code.
Figured I should respond to this too, with FI LTE/CBE and uprev I never got a cat inefficiency code. I used MD art pipes for a while as well and never saw this code. But even if a code pops up like this you can just drive till it goes away or reset and drive till all monitors state ready just like mag_black says. It should have no effect on passing the test in the end. Please delete this worthless thread.

We are dealing with different platforms here. I have an 03 Z and was tuned with Uprev with HFC's for 2 years and passed each year, however I still would have at least two sensors n/a or unsupported but it was enough to pass.

the third year, I swapped the HFC's for ART pipes and re-tuned one of 5 maps. I went for inspection and failed that same year.

The reasons are twofold:
1. subsequent years were there was unsupported or n/a codes(at least two)
2. Rom was flashed i.e. tuned. Massachusetts now knows anytime a ROM has flashed as it is not the original manufacturer code/serial number. --This was told to me directly by the inspector at the Mac center after I went for re-inspection and de-tuned and removed the ART pipes.

Something else had to have triggered the MAC flag, all of us have reflashed uprev maps. It seems more likely based on your previous post that you car was flagged some how for having sensors disabled for the past two years. I passed inspection with stock tune first, then uprev tune 1 , and uprev retuned. 4 years and 4 stickers with 3 different maps.

Before this my 3.5VQ maxima had headers, and in order to pass I used an O2 sim so that my rear sensors showed ready and defeated the CEL without disabling it. In the past you could have 1 or 2 read not ready and still pass, it seems like this is no longer true. The consensus I got from the different forums is that if you try to pass with disabled sensors now you will fail immediatly. Why even bother with disabling them its easy enough to fool the car into not throwing a CEL.

BUMPing this up as I was flagged. I am very worried as I don't think there is anything on my car that HASN'T been touched.

Trying to figure out what the best plan of attack will be. I need to make an appointment to go to the MAC. UGH

I got tagged too...back in January. So pissed about it. I finally got the flag cleared a couple of weeks ago and got my sticker on Saturday. I made my appointment with the Framingham MAC. He specifically said nothing modified. I had to bring my car to stock basically. No test pipes, no exhaust, no turbos, no flashed ECU. Everything back to factory.
