EMU 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.

Free, easy to install firmware upgrades further improve system capabilities (e.g. new strategies, trigger patterns, CAN data streams).

The EMU Black features more built-in value than any other aftermarket ECU. It easily matches the functionality of other stand-alone management systems with multiple inputs and outputs. Unlike many other ECU systems, the EMU Black has built-in wideband lambda input (Bosch LSU 4.2, and LSU 4.9 sensors wire directly in), MAP control connector (4 bar MAP sensor on board), 2 EGT probe inputs and an input to directly connect a Flex Fuel ethanol content sensor. All of this provides greater flexibility, reduces costs and negates the requirement for external or supplemental signal conditioning control systems and the associated wiring that other management systems require.

TECHNOLOGY

The EMU Black is assembled according to IPC-S-815A standards to ensure high reliability of the product. The device is manufactured on an automated assembly line with optical inspection, automatically tested including burn-in. The PCB board quality and design, special surface coating and IP65 enclosure keeps the device operational in the harshest environments. The components used allow continued operation in a very wide temperature range (AECQ-100 GRADE 2 (-40 to +105˚C).
