I have a ZC I am putting my '90 Hatch. I currently have a decent automatic tranny in it that shifts nice and firm. I don't want to go throughthe pedals, linkage etc. I understand my tranny will bolt up, but I was wondering what to do with the ECU ? 1. Can I re-chip mine effectively? Most everything mentions 5 speed. 2. What are repercutions if any on using a 5 speed Si ECU? Any input is appreciated!
