Hey guys hows it going. I have an obd2a 97 civic with an obd1 b16a swap. The swap was done with the b series obd1 engine harness. I have a stepdown harness to a chipped p28 ecu. The car runs and drives great, and is an absolute blast. There's just one problem. I live in jersey where vehicle inspection is kind of a pain to go through. The bug i have to work out is the diagnosis port where they connect the scanner doesnt work. What so ever. I connect a scanner to it and it doesnt read anything at all. Which turns the inspection process into a borderline impossible task. Ive looked up ways to make it work, but all i could find was that i need to use an obd2 ecu, but even then i have doubts about it working. Any help would be greatly appreciated. Thanks in advance.

 

Nope. You have to use the proper OBD2 ECU, and the proper wiring harness. That's it.

 

The obd2 port will not work without a obd2 ecu.

Mabye you can find a p2t obd2 ecu (96-97 delsol vtec usdm) to satisfy the inspection techs. He'll it might even run better lol.

 

I guess ill give it a shot. A friend of mine has an obd2 ecu ill borrow and see if it works. If it does ill just try to find an em1 ecu and call it a day. Thanks
