The PCM, or powertrain control module, is your vehicle's onboard computer. PCM Reprogramming or reflashing is essentially a software upgrade and may be required to resolve a hot or cold starting issue, idle roughness, stalling, or an emissions failure. If your check engine light is on, you lose fuel economy for no reason, or if your vehicle stutters or required multiple attempts to start, you may have a faulty PCM. It controls vehicle features such as emissions specifications, idle speed, and brake control. Carmakers create updates to the PCM software periodically.

A PCM reprogram may change the engine's idle speed, spark timing, and fuel mixture amongst other things. Bringing the powertrain to the factory specification should help it to operate as intended. Sometimes manufacturers will have software updates for your car's powertrain control module periodically.
