Erik, You won't have any problems swapping them out. John hervey www.specialTauto.com << I have an ECU unit (black box behind the drivers seat) that I'm not sure if it works or not. It appears to be good. The connections and such look good and the box doesn't have any problems with it. Would I damage my delorean if I swapped out ECU's to test? The ECU that I want to test came from an automatic, and my car is a manual. Where there any differences? >>
