A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...

These limiters may also retard the ignition timing. If using a soft-cut rev limiter, the engine will start to cut fuel or retard ignition timing before the set RPM until it slowly reaches it and remains there. If the engine over-revs anyway, a soft-cut limiter may progressively shut off each cylinder one by one until engine RPMs drop to safe ...
