Hi ppl I got in my hands a cylinder head and intake manifold y8 and the wire harness extracted from a Civic ex 2000 that was totaled. The Civic was automatic so i didn't mind grabbing the ECU because mine is manual. Did I do right or wrong by leaving that ECU and what ECU can I look for the best output?? I read S40 tranny is the shit I got one from a Junkyard, when I broke the old tranny seals one time and lock up on me. I also read that S40 comes in all 96-00 Civic but the EX S40 is what I should look for. How do I know what type of S40 I have (if they have differences from each other)?? I see a bar code and some numbers after S40 is that a way to know which one I have?? Thanks any info or links will be appreciate.
