I’ve come across an AEM EMS (crazy programmable ecu) that I can get for a lot less than retail, but on AEM’s website, it only mentions that it’s compatible with 92+ models. I know a few people here have used the EMS on 90/91 models, so is there something that needs to be changed on the stock harness to use the EMS properly in the 90/91 teg? ---

Couldn’ you convert to OBD1? That’s why its listed for the 92+ because they don’t make it for the OBDO Integra. Just a thought. I could be wrong. ---
