I am thinking of converting to OBD-1 for my B16A CRX to run Hondata. I used to have Zdyne, but want wide band O2 interface and Hondalogger. Also, I would like to run a single O2 sensor system, because the dual system seems so finiky in closed loop.

So these are the things I think I need so far:

OBD1 distributor from 92-95 Civic EX/Si and male harness plugs
P28 ECU
OBD1 ECU plugs to make adaptor harness
4 wire O2 sensor located at end of header near collector

Is there anything missing here that I should or must do?

 

ttt.

Really, am I missing anything? or does it sound about right?

I haven't decided on the Hondata yet either, I was considering the AEM unit too, and the switch to OBD1 would enable me to use the model for the 92-95 Civic/92-93 GSR.

I have been waiting for a AEM EMS race version since February. Can't wait around forever.
