CLEAN LS1 240

So let me get this straight. As long as the ecu running the motor isnt vin encoded/etched/what have you, (IE when its plugged in to NYSDMV it doesnt show up a VIN number and look like you just plugged a vette in to the computer while trying to inspect a nissan). NYS DMV doesnt know enough to realize anything is a miss. More or less it will look for readyness and MIL codes and either pass or fail.

I know for a fact that even if the car you are tyring to inspect has a VIN encoded ecu, and the VIN on the ECU doesnt match the one you scanned on the windshield to start the inspection, YET the motor and ecu are running 100% fine and will pass… it will pass and you walk out with a sticker. BUT when they upload to DMV, they might get flagged becasue of the missmatch. So either the shop or the registered owner might get a letter.

So, that tells me the first assumption is correct. If say this ECU is wiped clean of any trace what car the donor was, NYS will be none the wiser. it will pass as long as its running fine. And even if its vin encoded with some other car it will still pass, but might get caught once its uploaded to nys.

My next question for you GM ecu gurus, how hard is it to take say an LS3,6,7 or what ever out of a newer chassis than the classic LS1 and blow out the VIN and donor vehicle information so its more or less an empty ecu running the engine?

I think you’re giving dmv too much credit. To my knowledge looking at inspection records at work if there’s no vin recognition and the machine doesn’t pick up on it all the DMV sees is the VIN scanned and the result (pass or fail)

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.
