EMU Black w/USB-C — Standalone ECU
ECUMASTER EMU Black: Advanced Engine Management for Complex Applications
The ECUMASTER EMU Black is a versatile and powerful engine control unit (ECU) designed to manage the most advanced and complex spark-ignition engines. As the successor to the proven ECUMaster EMU, the EMU Black offers enhanced capabilities, making it ideal for modified race cars, passenger cars, motorcycles, boats, and stationary engines.
Key Features and Benefits:
Advanced Drive-by-Wire Control: The EMU Black features sophisticated drive-by-wire throttle strategies, ensuring precise control with built-in reliability and failsafe measures. Continuous firmware upgrades (free of charge) further enhance system capabilities, including new strategies, trigger patterns, and CAN-Bus data streams.
Comprehensive Built-In Hardware:
- 4-bar MAP Sensor: Reads manifold pressure up to 43 psi of boost.
- Integrated Wideband Controller: Compatible with Bosch 4.2 or 4.9 sensors, eliminating the need for an external controller.
