Hey your're right, I don't have experience in that arena, maybe you could answer some questions in this thread: https://www.honda-acura.net/forums/s...threadid=76010

I'm pretty lost, and could really use everyone's help.

Why would you want to run an OBD2 engine with an OBD1 ecu? OBD1 wouldn't be as efficient as OBD2 ecu right? He can just interupt the ecu memory's power, then just tune it with a piggyback or something. When he goes to smog test his car, the ecu won't remember anycodes.

 

There isn't an issue with efficiency, it's an issue with complexity.

OBD generations continually get more and more complex as the ECUs use more sensors to help tweak the fuel and ignition maps for the engine they're designed to work with. As a result, they're able to more accurately and precisely pinpoint faults in the system, which is what OBD is all about anyways, On Board Diagnostics.
