Hello, we currently have a 91 integra LS (non-vtec) and the engine ahs died. We are currently replacing it with a b20b3 engine, again non-vtec, with the aim of eventually doing it up. We are investigating ECU replacements and have found that teh APEXi PowerFC seems to be fairly popular and right for our needs. Can this ECU be fitted to the existing loom of either the old b18b engine or the new(ish) b20b? If not what loom must we acquire?
