Only part of code they care about.
Scan… did we get our money… can we make them scan again for more money… damn… PASS
Lol that machine knows more than u think lol , the dmv rep that covers our area has shown us the info that machine sees . There is a reason I no longer will do a obd2 car that was hack tuned or swapped . Yes I got bit on a lightning that was so called tuned locally . They check monitors , mileage , sensor data etc . It’s actually a damnit smart setup . U may get the sticker ,but soon after either u and or the shop will get a visit and quite possibly a pull of your reg .
The answer to all those statement is it depends on the vehicle. GM ECMs don’t have vin rec until 2001 or 2002. So in the case of the nissan you could inspect it without it being redflagged if the PCM is old enough. Otherwise it woud be flagged. Honestly I’m not sure what DMV would do if you say LS swapped something newer and got it to pass. Part of me says as long as you left the emissions stuff intact it might be ok. However I’m sure there are plenty of laws that if strictly interpeted would say it’s illegal. Hell technically if you want to read some inspection rules a certain way an non OEM emission parts could be grounds for a failure.
So what if you have a vin encoded ecu becasue you are running a ls7 lets say, why not go over it with HPT and enter the VIN of the car you are putting the motor in and lessen the chance of a flag coming up. And mileage if its stored on the pcm, etc. Convert as much data as it can.
Also you are saying it watches data streams too. I understand that it it probably would like to see post cat 02 voltage movements, evap relays opening and closing, and everything else when its plugged in for a pass/fail. BUT I have 2 cars that I know for a fact those sensors would have shown ZERO movement, but becasue the monitors were hard set to pass, it was plugged in, tested and passed with no problem. Thats was even with the engine NOT running, just key on. Infact the guy doing the inspection bet me $12 or what ever the cost for a retest after a fail cost, I would fail becasue I told him the engine didnt even need to be running. He said the same thing, it must be running or it will fail. Needless to say he was blown away when it passed and my cars didnt make a peep. So that right there tells me that they dont need to see data flowing in order to green light the car and pass it.
BUT, like you said, I would assume that if the daily inspections were audited it would see zero data when there should have been and raise an eyebrow. If my registration is yanked 8 months later, cool. I will just sell the car to my wife and do it all over again. (I probably could also take it off the road, and a week later re-register it anyways)
Also, like you guys said, modifications to cars are illegal, so none of this matters. It doesnt matter that you are taking old technology and replaceing it with newer, more efficient technology… its still wrong. But hey, you can still take a 1994 what ever and put a pile of shit gas guzzling ozone killing POS engine in it and thats just fine.
As long as your monitors have run a complete test and you have no codes the state and their computer are happy, I’ll leave it at that.
Think about it this way. Across NYS how many thousands of inspection are done everyday? Even if all the data could be logged and stored for a short period of time you would have to do something to throw a red flag. I do know for a fact that a guy I worked with got in trouble because he plugged the wrong vehicle in for an inspection. He had a truck and a car that were both getting a sticker was in a rush and accidentally plugged the truck in twice. DMV flagged it and paid the shop a visit about a month later. Wound up being a big headache and one very pissed customer. Moral of the story make your stuff legit as possible and don’t call attention to it and you should be fine. In the case above the inspections were flagged, because the machine saw the same vin from the PCM twice even though different registrations were flagged for inspection.
Understood. My point is this. The Emissions computer looks for completed monitor tests. It doesn’t look for codes. It looks for ready or not ready. No matter whether a monitor passes or fails it’s test as long as it shows ready then it’s good to go. A completed test will show ready no matter what as long as there is no codes set…with me?..lol
Every p.c.m has a calibration code specific to that car line and model . Alter that and ya have a issue , say I’m wrong all u want I know for a fact it does . Yes only newer shit has vin etching etc but every p.c.m has a calibration I.d …
more info on the calibration code. this is news to me.
he’s talking about the part # for the factory tune in the car. Basically even though it’s not looking for a vin it’s looking to see that a 97 chevy has a 97 chevy tune. And you can change the tune all you want as long as that CalID stays the same, or one of the updated CalID’s from the factory. Beyond that the state computer has no clue what it’s looking at other than Ready/Not Ready.
A lot of rumors in here. What we need is someone with enough programming knowledge to tap into the data line for OBD2 and go get an inspection. Gather and understand the data that is sent to the inspection computer.
Slomarro, yeah its better to be safe than sorry about inspections but I don’t believe the state is as smart as you think they are. While the chips and software from the ECM can and do have a serialized number programmed into them that can be read, the state inspection computer and software probably can’t read all of that information or even if it did, keep that data in a database and cross check it with some manufacturer database.
The state is doing inspections for money.
My Crv didnt pass yesterday, 3 pending codes. BWAH
I cant speak for the GM ecu 100% but I can for the VW one. I put 3 cars through inspections and got stickers for all three.
-
stock ecu in stock chassis. Big turbo flash over that ecu. The VIN stays the same when looking at it on the laptop. The component ID was altered from factory (assume thats the same as the configuration code you gm guys are talking about) and had 1.8 830 BT blah blah blah in it, letting the tuner know what was flashed as a baseline on the ecu. SAI, rear 02, evap, maf, and other stuff was written out. their values when logged were 00000 when the car was running. Readyness for them were hard set to pass. This one was the car I plugged in and passed without the car even running.
-
Same ecu above, put into my other jetta with none of the BT stuff installed under the hood. Vin on dash wasnt the vin in the ECU. Same hardset/ommited everything above. Once again, passed without a flinch.
-
Just got an ecu back from C2 for a 100% stock jetta. SAI, Evap, and rear 02 written out and hardset readyness. Component code again is different, vin is the same. Passed with flying colors. IMO is defeated, and that ecu can run in any other wideband year MK4 1.8T golf or jetta, and pass like my second example above too. I would put money on it.
And with the component or code ID stuff, thats usually the spots where the tuners append as a notes field on the ecu to tell them what file they were working with. So chances are that field isnt going to be left the same if the car was tuned. I know for a fact thats true from my expierence above.
thats it? we have a trailblazer here with 26 codes that came up when it came here wondering why it failed nysi. hahahaha
26 codes eh ? Sounds like a ign switch fucking everything up again lol
DMV still uses fucking floppy discs :rofl a little outdated
