Hey everyone,

So the law changed in my state to where I HAVE to have communication between OBDII and the scanner. but they say they can read an obdi with the same machine. so I was wondering if I could switch to obdI (since the engine is OBDI) and have it tested that way.

any thoughts on this?

I don't understand what the problem is? You need to get a state inspection? Is your CEL on?

Whoever told you an OBDII scanner can read OBDI codes is completely wrong, unless the code reader is specifically designed to also read OBDI.
Also, by federal law you cannot go backwards with your emissions parts, but you can go forwards. So you're not supposed to swap a 94 ECU into a 96, but you can swap a 97 ECU into a 96.

Also, if your car is OBDII and part of the inspection is hooking up the inspection machine to your OBDII port, you can't swap to OBDI and pass the inspection. If they just do a visual it's still illegal, but they may not notice.
