Be Careful with UpRev in Mass

crystalline

The only thing I find confusing about the information in the entire thread are the statements here. So its being stated that any reflashing will trigger the machine to immediately send the car to MAC to be inspected by the state police. This is quite scary that even if nothing was changed on the car reflashing alone from the stock ECU would send the car to MAC. However, how does the machine determine dealer vs uprev reflashing? Does it have some sort of method or database of every stock ECU so it can compare/determine that there was a non authorized reflash?

This is where I am confused. If an all stock car was given an uprev reflash in this test why would the car not be transmitting all readyness codes and all hardware available? If nothing was removed and the car is all stock there is no need to delete CEL codes. I would 100% believe MA has a way to check now for removed/deleted codes and send you to MAC for inspection. But I cant quite understand how if your CEL is off naturaly how/why they would flag you and send you to there.

Speaking to Dent today they dont turn off any sensors on a NA car with cats. They are putting a car out for testing now with a Stock Uprev rom to see if it is detected. Lets be clear here, NO sensors are being turned off. My car would not require such things to be turned off, NA car with a muffler delete and Typhoons.
Whats troubling here is the amount of people that want to tell us this is not happening when in fact it is. If you think I want to argue in order to spend $600 thats just foolish. But the way the guy from Uprev acted not only to me but to Dent really makes me wish there were other vendors.
We shall see.

If the ROM ID is changed, MA emissions will see it. If the UpRev tune uses the OEM ROM ID, then you should be ok. We don't tune UpRev here, so I haven't delved into it that deep.

We two maybe put two and two together , If the Stillen and GTM's UPREV reflash is Carb legal , It maybe safe to say, that UPREV uses the OEM ROM, And is I remember correctly , My first tune on my car( N/A) They had to call UPREV with my ROM ID becasue they had no tune for it yet? Others I know have ran into this issue,. So this would mean they use the OEM ROM ID?

I went and read all the EVO threads now as well. Change number one was MA getting smarter about systems showing ready or no cel when the ECU has been reflashed. Doesnt seem like an issue with most people with a Z as you can remove the cats and not have a CEL. I wouldnt be concerned with this as a visual inspection alone can fail you with removed emissions equipment.

Change number 2 is the concerning one, and it seems like MA tracks this ROM ID every year. So if you changed it, its going to flag and fail you even if the car says its ok. Unanswered questions, does Uprev change this ID? The guy who had an EVO switched from a euro ECU back to a US one which triggered the visit to MAC. I dont think Uprev would quite do the same thing. Also is this tracked in a statewide database or just at each service center? Anyone know if the inspection machine is hooked up to the internet?

Uprev keeps your ROM ID. They download the stock data, make modifications and then re-upload. You can export and move ROM files around but that is not typically the way it is done. If UpRev doesn't recognize your ROM ID group then it doesn't let you work with it, that is a safety mechanism since there are subtle differences between auto's and manuals, touring and base, sport, non-sport, and all the permutations thereof etc. The ROM ID can change on the manufacturer's whim as well, or to indicate or to indicate a revised ECU between model years.

Yes, the inspection stations are online, typically via dial-up. The information collected by the scanner is sent to MA RMV, you don't get a sticker until the information is successfully transmitted and verified.

So if uprev doesn't change the ROM ID I don't see how this stock car with no mods and only an uprev reflash could have been sent right to the MAC?

ChrisSlicks

It would seem that the RMV computer has been updated to look at more than just the ROM ID and readiness test states. No idea what precisely, you would have to put a logging device inline between the car's OBDII and the RMV computer to see all the back and forth communication. UpRev does hide a license signature in there but I doubt they are looking for that (but who knows).

If it doesn't belong there then its an easy thing to target

thisishk350- it wasn't insulting it was just a poorly composed effort at showing off your analytical skills.

I took time out of my day to try to share what we know regarding this mysterious process which is taking place seemingly three-thousand miles from you.

We don't have all the answers and as Vivid has added, it's not just us and not just Nissans that are experiencing these problems here in MA.

Usually when people take the tone and attitude that you did in replying to me it indicates a personal stake in the subject. I hope this works out for everyone.

Update, They tested a car with Just flashing a license on it, NO other changes were made and the car failed. This is a Stock car with no mods that would cause a failure. So it would appear their license signature changes the Rom enough for the computer to reject the car refer it to the MAC.
Dent has told me 50 times they WANT to tune using Uprev as it is a very good product but cant afford to have customers coming back to them with rejections.
It seems now that people in Mass that are getting inspections going forward will fail if they have changes in the Rom that the state is able to see.
Someone needs to find a way to get an image of the stock Rom/ecu to reflash it back.

Bummer for me until someone figures this out.

Why is it so hard to give details, So the car was flashed with the UPREV stock tune? I like the elussivness" on a stock car with no mods that would fail", So does it have mods off anykind or not, Was the car driving for the 90-100 miles for the ECU to reset, There are to many holes in this story AGAIN. But just food for thought how does a 500 WHP GTR pass and you stock car with what you say with NO mods pass?? Just curious. This whole thread is still full of usless information and should be closed.

If you wanted to help some one you would list the mods if any, or say "COMPLETLY STOCK" not" With no mods that would fail". I'm done in here

It looks that way. I wonder if anyone with a CARB-certified F/I kit is passing MA emissions. If so, then it's a matter of getting a tuner or UpRev to take a hard look at every single difference between the CARB certified can tunes and the other tunes.

If you reset a factory ECU (bone stock everything) and go through emissions without going through the drive cycles and setting all of the readiness alerts, will you get flagged for further inspection or just fail? Here in AZ, we don't get flagged for additional inspections. If we fail, that's it. We just have to come back later and retest.

Looks like we're on the same thought process as far as readiness alerts and whatnot. The reason the GTRs pass is because they don't use Uprev... GTRs are tuned with either Cobb or ECUTEK primarily. Also, a lot of GTR owners have the means and/or connections to circumvent emissions laws.

NO mods=NO mods, No mods that would cause a failure = Typhoons, Short tails ect. But since you are Done here its good as you have added nothing but some foolish conspiracy theory. Maybe you should just pay your bill and move on.

I don't see why people are flaming Evil over this. It's a forum, not a class on analytical research and composition. How hard is it to ask for clarification? He's (I'm assuming gender) been pretty active on updates regarding the tests done.

I could understand some sore a$$es regarding Uprev customer support and all the fans they have regarding their software, they are generally prompt and abrupt, not the friendliest, but I do get answers with quick replies. On the other hand, their tuning team is great all around.
