It might be time to check your car's Engine Control Unit (Aftermarket ECU Upgrades), also known as the Powertrain Control Module (PCM) or Engine Control Module (ECM).

PCM: The PCM is responsible for coordinating the functions of the engine, transmission, and other powertrain components. It acts as the brain of the vehicle, ensuring seamless communication and operation of these systems.

Here is my web blog ... Ignition Timing Adjustment

ECUs, PCMs, and ECMs rely on sensors that monitor various parameters such as engine temperature, air intake, throttle position, and more.

The Powertrain Control Module (PCM) and Engine Start-Up Sequence Control Module (ECM) are terms often used interchangeably, but they serve distinct purposes.

Regulates fuel delivery based on engine load and speed
Controls ignition timing to optimize performance and efficiency
Monitors emissions levels and adjusts settings to meet regulatory standards
