any ecu from a knock sensor car, needs a knock sensor. Early S2's didnt have a knock sensor. So no, it won't fit...

Rick i think you will find they will all fit different cars and have the same pinouts but as you say if you fit a late ECU designed for a knock sensor to a car without one it will run like a pile of poo
