help?

The PCM (or powertrain control module) controls all electronic aspects of the engine which bascially means everything. From fueling and Air fuel ratio, to fan speed and sensor monitoring. It also has things such as torque limiters, the ability to reduce power and other "negative" things to help protect the motor from abuse.
