ECU Master Black

ECU Master Black


The EMU Black is a class-leading, stand-alone engine management system, designed to operate the most advanced and complex engines available. It is a successor of our proven system, EMU. Throughout EMU’s lifetime we collected lots of data that allows us to substantially improve the device hardware and software.


EMU Black targets race cars, road cars, motorcycles, boats, and stationary engine applications.

The EMU Black controls fueling, ignition and auxiliary systems on 1-12 cylinder engines including those with drive-by-wire throttles and VVT.


It can drive up to 6 passive or 12 smart coils directly and does not require external amplifier/power modules to achieve this. Sophisticated drive-by-wire strategies provide a wide range of throttle control along with advanced plausibility (fault/error) checking for safety.
