The BMW Mini Cooper S R53 G4X plug-in ECU is equipped with internal ignitors to meet the requirements of the factory wiring loom. (This means that ignition coils are wired directly to the ECU).
The internal ignitor can drive 10 amps of current through each ignition channel. It is important not to exceed this current when setting dwell times or fitting aftermarket coils. Internal ignitors are only present on IGN 1 and IGN 2
