BMW M50TUB25 Internal Ignitor
The BMW M50TUB25 G4 plug-in ECU is equipped an internal ignitor 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.
