The journey of the ECM, also known as engine control module, reflects the wider development of vehicle technology that has changed vehicles from basic machines into sophisticated, computer-driven entities. In the early days of vehicle engineering, carburetors were the center of the engine, managing the air and fuel mixture to enhance performance. However, as vehicles became more advanced, the constraints of mechanical controls became obvious. This led to the introduction of dig
