EFi Engine Management Systems
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.
Euro-1 is a low cost ECU from EFI Technology. Originally developed
as an OE system, it provides extremely good value in performance-to-cost
ratio. Based on well-proven technology, Euro-1 was developed for
use in road cars (where OBD is not required), high performance sports
cars and club rallying.
Euro-1 is designed around a NEC 16 bit 16 MHz microprocessor and
has a high level of facilities.
Euro-1 can operate fuel injectors having in excess of 8 Ohm impedance and features closed loop fuel control to obtain lambda 1 and self-mapping fuel injection strategy. Furthermore, closed loop boost control and idle speed control for both air by-pass valve and stepper motors are available.

The ECU crankshaft sensor input can be configured for either magnetic or Hall effect sensors. In addition, individually configurable NTC temperature sensors can be attached, as well as an individually configurable 0-5 volt analogue input is available.
Euro-1 was selected as a controlled ECU for use in Germany in the DTC 1600 class for touring cars with an engine capacity up to 1600 cc for the 2001 and 2002 season.
