I couldn't find a definitive answer on this one. I was having a conversation earlier this morning, and a P73 OBD1 was mentioned. I wasn't sure if this guy knew what he was talking about or was just shooting from the hip. Had never heard of it, only OBD2. Does it exist? If so, I would assume it was/is JDM and would have a 112mph speed limiter. Is any of this true?

Thanks in advance.

 

its still a 96+ ecu but it lacks the extra sensors to be true OBD2, though I wouldnt
call it OBD1 either. Just call it JDM ITR ECU

 

If its like what Sgt said, it will have the OBDII style plugs, which is what i think your trying to find in OBDI form. All 96+ ecu utilize the newer style plugs.

 

I just heard about someone selling obd1 p73's, that need a obd1->odb2 harness? in fact, i found an item on ebay matching that description, which was separate from the conversation i had earlier today. (no, i'm not interested in the iteam, just wondering what the heck is going on!)

Any idea what is going on here?
