The M52TU engine from BMW is almost the same as its successor, the M54 engine. Except for the throttle body and pedal it shares all sensors with MS43 powered M54.
It's not a complete plug & play operation to update the ECU from MS42 to MS43, but we try to make it as easy as possible with this guide.
Install Electronic Throttle Pedal

M52TU cars dont have seperated +12V lines for ignition coils and injection valves, so you have to connect pin 7 (red/yellow) with pin 2 (red/white/yellow).
