At its core, ECU design begins with the selection of a robust microcontroller capable of high-speed data processing. Modern vehicles require real-time execution of complex algorithms to manage fuel injection, ignition timing, and emission controls. The design process focuses on creating a multi-layered Printed Circuit Board (PCB) that can withstand extreme temperatures, vibrations, and electromagnetic interference (EMI). The internal architecture typically includes: Microprocessor: The central logic engine.

Analog Inputs: Variable voltage signals from sensors like Throttle Position (TPS) or Coolant Temp (CLT). At its core, ECU design begins with the
