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.
