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. The main 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).
