In Ohio the VIN in the ECU needs to match the vehicle or the system won't say the car is good to go even if it is VINs are matched to the state data base of car registrations. First thing the test guy does is read the VIN thru the windshield of the car and plug into the computer. Poof! Up jumps the registration data.

The self-service stations just read the ECU but the data prints out on the pass/fail paperwork. Which will be different than the car's VIN,

Remember none of these modified ECUs are legal for street cars. Printed right on the box.

I live in Chapel Hill NC. Passed emissions at a Firestone with my K-Pro no worries!

Not sure if the vin gets updated or not but since you can do just about everything else I wouldn't doubt you could type the VIN in the computer.

 

^ what he said. I've been running one in my car for years and it has always passed emissions... I'm selling it too lmao, but I'm not just saying that because I have one for sale. It's the easiest. If you go with the kpro you have to switch over a lot of sensors...

 

I lived in NC for about a year. From my understanding, you can just register the car in a county that doesn't require emissions testing. May be easier if you live near a county that doesn't require it.
