ECUMaster EMU Black – Standalone Engine Management Unit

Product information

The ECUMaster EMU Black is a high-performance standalone ECU designed for demanding street and motorsport applications. With advanced control strategies and extensive tuning options, it offers precise management of fuel, ignition, boost, and additional engine parameters – ensuring maximum performance and reliability under all conditions.

Built on modern hardware with powerful processing capability, the EMU Black supports features such as sequential fuel and ignition control, wideband lambda input, onboard data logging, and advanced boost control. It is fully configurable through the ECUMaster software, allowing tuners to optimize the setup for naturally aspirated, turbocharged, or supercharged engines.

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

The ECUMaster EMU Black is capable of managing fuel, ignition, and auxiliary systems on engines ranging from 1 to 12 cylinders, including setups with Drive-By-Wire throttles and Variable Valve Timing (VVT).

It can directly control up to 6 passive coils or 12 smart coils without the need for external amplifiers or power modules. Advanced drive-by-wire strategies offer precise throttle management combined with robust safety checks for maximum reliability.

With free firmware updates and great customer support, the EMU Black continues to evolve, adding new strategies, trigger pattern support, and CAN data options — ensuring your ECU stays up to date with the latest features.
