Euro-12 Engine Management System

EFI Technology is a company specializing in advanced electronics for motor racing and high performance road cars. It was founded in 1985, initially to design and develop the early electronic engine management systems for an F1 engine builder. Today, EFI Technology is a highly focused company involved in developing high tech engine control systems for the most demanding classes in Motorsport and in high profile sports cars and motorbikes. EFI Technology manages and supports the complete project, from customer specification through hardware and software development, to production and testing of final products.

Based on the latest technologies, EFI has developed a new series of 32-bit high tech ECU’s. Euro-12 is our top of the range ECU and is in particular developed for use in sports cars and touring cars, in rallying and as a development ECU for automotive engine development. The ECU is designed around one of the fastest microprocessors available and has a high level of facilities, including ASAP3 communication with AVL’s Puma system.

Euro-12 has programmable fuel injector drivers for low and high impedance injectors, closed loop fuel control and self-mapping fuel injection strategy based on the use of both standard and linear lambda sensors, a closed loop self-mapping boost control strategy and programmable knock control. In addition, the ECU is fitted with an on-board high-speed data logger with 8 Mb memory capacity.

The ECU crank- and camshaft sensor inputs can be configured for either magnetic or Hall effect sensors. Furthermore, several individually configurable NTC temperature sensors can be attached, as well as several individually configurable 0-5 volt analogue inputs are available.
