I have an ecu that I pulled from a 87 N/A and I can't find any identification on it besies the number DZ-A01 stamped into its face and 27 Aug86 AA on the part where you plug the wirning harness into the computer. I think its a N326 but I can't be too sure. I'm trying to find a replacment ECU because I think this one is bad and i've searched to find that a N327 is also compatable with this. Can anyone give me a hand with this situation and confirmation on what ECU models I can use with my car?
