The EMU Black controls fueling, ignition and auxiliary systems on 1-12 cylinder engines including those with drive-by-wire throttles (E Throttle) 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).
Decades ago, the critical electronic components in a race car were the ignition coil and points. Race cars now feature advanced engine management systems, antilock brake systems, paddle shifters, dataloggers, radios, electric pumps, fans, and lights. All components need to be controlled at the correct moment, and all components require circuit protection to prevent damage or fire.
Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics.
All of these problems can be solved by using intelligent power management units (PMUs). Our newly developed PMU unit is at the forefront of technology. It provides 16 high current outputs (and use of multiple units if more outputs are required).
