As the title states, I have a 1996 OBD2 vehicle with a GEN3 swap, and I need to get it inspected. The shop tried plugging in to the OBD2 port, but it would not communicate with the state software. What are my options? Is there a wiring fix, would a standalone help? I am sure I am not the first person trying to inspect an OBD2 car with a JDM engine in NJ. I hope there is an easy fix here.

Swap in an OBD-II 5S-FE to have it inspected, then swap back to the 3S-GTE afterwards. What most people do since the 3S-GTE ECU is JOBD and a standalone won't be OBD-II compliant either. That or if inspections are a problem for OBD-II vehicles they swap an OBD-I car instead. Being you're new it sounds like someone sold you their car after they figured out they wouldn't be able to get it inspected.

No wiring fix - all wiring is good, but JDM ECU uses a different OBD2 protocol (there are several).
Standalone will not talk to the state computer either. It's illegal for standalone's to do so (they're technically off-road use only), so they don't.
Either get ready to swap the engine every year, get a 94-95 chassis, or dive into the world of 2 computers running your car - fool the "legal" one into thinking it is running the show (with all the emissions crap it will look for) while another computer (standalone or your JDM one) runs the engine.
Allegedly there are shops out there that will hook you up, but it's kinda difficult in NY (read: expensive) as NY state software is pretty sophisticated newer generation emissions crap.
No easy fix for this one. If you find one, let me know. I'm in the same boat and would really appreciate that.

yep those are your only solutions. if you are good at swapping engines, throw a 5S in there, get inspected and then swap back.

On the bright side, if you get good at it, swapping the engine in and out can be done in a day! Last time I pulled mine out in 6 hours I think, and even less time to put it back in. And that was all by myself cause my LeMons teammates are that good. Keep all the wiring mods within the engine harness, and you'll be golden.
Or, get it registered in PA as a recreational vehicle driven under 6k miles/year. Then, anything goes

This is surprising to hear. I wonder how all the EVO's and STI that are running standalones do it

They flash their existing ECU so the OBDII port still works.. We cant do that because our ECUs are encrypted.

yep those ECUs are flashable. toyota are not
