We have recently performed a swap on a 94 mustang, from a v6 to a v8. This car has an auto trans, with the required v8 wiring harness, v8 computer, v8 throttle body, v8 gauges, the whole 9 yards...but we are using the same trans from the v6 for the v8 if it means anything. now, when we bought the v8 motor we also recieved a v8 computer but for a manual trans, so naturally the car wont shift but the engine runs great. So to fix the problem we bought a v8 manufactured computer from an IKT store, now the trans shifts but the engine doesnt run right.Missing dont act like fuel is meetering right no power Any help?
