Default passing inspection with a swapped car in NJ?

i just got my swapped rs on the road and im overdue for inspection, being that nj only checks emission now should i have any issue passing? since its obdII they should only be plugging it in but what im wondering is whether they only check the monitors or do they also see the vehicle data?, cause obviously the vin for the ecu wont match my rs vin. just wondeing how things went for those who have a swapped car and have been in this position before, thanks

You should be fine as long as it comes up when they plug in the obdII port most places won't even bother to check anything other than readiness and if it passes. I would bring it to a place pay the 50 dollars and get them to do it though because if you do fail getting a sticker becomes alot harder.

As a matter of discussion purposes, by rights there would be a matching of the VIN and the ECU for emissions testing purposes. Why? The mandated emissions standards are per model-year. Thus, they would be trying read your 'new' ECU versus the VIN matched ECU.

You may very well have to have the car re-registered as a composite. That may mean you would have to prove where the engine/ECU came from and once verified, they would then have in their system the fact you have 'upgraded' and thus they would be able to correctly test your car.

So what though. I can keep going on about theory all I want.

Contact the NJ DMV and find-out what's what.

It will pass just find as long as they can communicate with the ecu, no cels are present and the readiness monitors are active

So long as you are not throwing any codes and it is a USDM engine/ecu you will not have any issues in the state of NJ. All three of my swapped cars have passed at both state run and private inspection facilities.

Any updates on this question? Specifically, I am curious if anyone has inspected recently with an ECU whose VIN does not match the chassis VIN. This would be for a USDM ECU/drivetrain.

I've heard some stories to the opposite, where the inspection computer checks the ECU-reported VIN against the VIN on the registration paperwork, insurance card and dash plate.

One of my cars was inspected last month AT a state facility, no problems at all. I don't know that they actually check the VIN to the ECU.
