I just moved to NJ from an inspection-free state. I haven't done the inspection myself yet, but have done some reading on what to expect. They just plug in the computer to check the emissions systems.
Unfortunately, they check for readiness of all emissions systems. Stage 2 tunes typically disable rear 02 readiness so you don't get a CEL from your downpipe.
So far I've heard of two options:
1) reinstall stock downpipe and flash back to stock
2) install rear 02 spacer and reflash to stage 1
Same here, I got some occasional -2.25 pull when it's hot out on when I was Eurodyne stage 1.
I thought the cobb stage 2 didn't clear the check engine light from a dp install. I have a spacer on mine and drove around for a while before tuning and didn't throw a code.
You can pass NJ inspection without headlights installed in your car. Pretty sure you'll be ok. They only run exhaust test if you have an engine light, no?
Yeah they just plug the car in and check codes and they might drive it over a camera? Not 100% sure.
In any case I'll just flash to stock just to be safe.
