I have a P72 on my GSR and I want to dyno tune my car with a hondata. I dont want any downtime on my car because its my daily driver and I dont want to send it off my ecu to get socketed. Anyways my question is does it matter if the P28 ECU came from an automatic car? I dont think it will make a difference but I want to make sure before I buy it. Let me know if I can use the P28 OBD-1 that came off of an automatic ex on my OBD-1 Gsr motor. Thanks
