Obd-1 or Obd-0

[94H_Ex]

Well I'm looking into the p28 ecu into a cb7 accord. (90-93) I want to turbo one day so I'm looking to research into this more.

Hondaswap's reference says obd-0

91 accord obd0 or obd1 - CB7Tuner Forums

This site says obd-1. Anyone else have any input? As well, when doing the p28 swap is there anything I need to change for the harness (other than run the vtec wires) or change some pin outs? I've already found maps for either the F22 with F23 head, or H22 to go into the P28 ecu.

No input?

Edit:

Nevermind, I went out and did the leg work and turns out I have an obd-1 system. My car is a 1990 Honda Accord Ex, came stock with a F22A1, 5 speed.

There was alot of talk through some researching of possible pre obd0 systems in accords, from what I gather on my serial numbers on the dash is my Cb7 was made in USA, and was the 456 one produced. So.... pretty much no pre-obd0.

anything from -91 is obd0, anything from 92-95 is obd1 and anything after 96 is obd2
