ECUMASTER EMU BLACK is a universal engine control computer that manages the operation of spark-ignition engines and is designed to work with the most advanced and complex currently available engines. It is the successor to our proven system, the ECUMaster EMU. Common applications for the EMU Black are modified race cars, passenger cars, motorcycles, boats, and stationary engine applications.

EMU Black features sophisticated strategies for drive-by-wire throttles, providing a wide range of control with advanced algorithm reliability (fault/error) and failsafe provisions. System capabilities will increase over time because of the ease of upgrading (free) firmware (eg. New strategies, trigger patterns, CAN-Bus data streams).

The EMU Black is one of the best values in engine management available anywhere. Built-in hardware includes a 4 bar MAP sensor (for reading manifold pressure up to 43 pounds of boost), a built-in wideband controller (just add your choice of a Bosch 4.2 or a 4.9 sensor, no external controller needed), 6 built-in high current ignition drivers (can drive smart or passive coils, up to 12 smart coils for waste spark), 2 EGT inputs, CAN and Serial on board, on-board Drive By Wire control, and much more. All of these features in a beautiful CNC Aluminum enclosure that's small enough to fit in your hand.
