surprisingly common misconception, but no, all CB7s were OBD1. 3rd gen up till 89 were OBD0.

yeah....trsut these guys....they started a freaking website dedicated to this sh*t..i'm pretty sure they know..i know as well, but yes like mike said, all cb7's (90-93) are obd1. I'm not for sure so dont hold me to it, but there MIGHT be--might be--a very select few early early made 90 cb7s that may have been obd0 but its probably just a rumor or something i heard somewhere stupid

thats the misconception im talking about

Correct. Every CB7 was OBD1. OBD2 started in 1996.

3Geez aren't all OBD0 though (not that it matters here...) some of them are "pre-OBD". Made things irritating when working with my 86, which falls into that category. Slightly different things going on, I found.

Let's bring this thread back from the dead for a sec..My friend jus told me that my car is OBD0, since I have an LED on the ECU to read codes instead of a jumper..I haven't honestly checked whether I have that jumper or not (the blue service connector), but I always thought that OBD1 still uses the LED on the ECU to read codes?

Anyways, how to tell whether yours is OBD0 or OBD1? I'd be freaked if my car is one of those rumored early 90s CB7 that still uses OBD0

forget the stupid rumor, it's 100% shit and that's that.....ALL cb7's were obd1, no obd0 or obd2 or obd69 or any of that shit..........friends usually don't know shit, that's why i have none.....they're 100% liability OR they're geniuses and you're the friend who is a liability.....you have the jumper unless someone cut it off, but unless someone went to the trouble of converting your car to an OBD0 setup (different EVERYTHING, engine, tranny, etc) then you have an obd1 cb7
