ECU
An ECU (Engine Control Unit or Electronic Control Unit) is like the brain of a modern vehicle. It's a computer system that controls various parts of a car's engine and other systems. Think of it as the device that takes information from different sensors in the car and makes decisions about how the engine should run, how much fuel to use, or when to shift gears in automatic transmissions. Similar terms you might see are PCM (Powertrain Control Module) or ECM (Engine Control Module). This is a crucial component in modern vehicles, and professionals working with ECUs need to understand both automotive systems and computer programming.
