Introduction
An engine control unit (ECU) is the electronic brain of modern vehicles, managing fuel injection, ignition timing, emissions controls, sensor inputs, and actuator outputs. This post covers ECU architecture, electrical and mechanical design considerations, a typical full pinout with signal descriptions, PCB and layout best practices, power and grounding, diagnostics and communications, and testing tips for hobbyists and engineers.
Designing a full pinout from scratch (for a custom ECU like a Speeduino, ECU Master, or a Motorsports ECU) requires a systematic workflow.
