Wiring Diagrams

EC61 ECU — a high-performance engine control unit (ECU) designed for engines with up to 8 cylinders (or up to 16 cylinders in dual ECU synchronization mode).

• Architecture based on a 32-bit ARM processor.
• Supports engines with up to 8 cylinders.
• 8 High-Z injector driver channels.

• Flexible configuration for various sensors and ancillaries.
• Injection strategies: Simultaneous, Semi-Sequential, Sequential.
• Ignition strategies: Distributor, Wasted Spark, Sequential.
• Load calculation algorithms: Alpha-N (TPS), Speed Density (MAP), MAF.
• Supports any trigger wheel configuration — software configurable.
• Real-time tuning (Live mapping) on a running engine.

• Crank trigger wheel (semi-sequential injection, Wasted Spark).
• Crank trigger wheel + Cam phase sensor (fully sequential injection and ignition).
• Cam trigger wheel (sequential injection and ignition).

Power Outputs:

• 8 Low-side outputs (ground switching): injectors, relays, solenoids, etc.
