Racing Computer Systems

We specialise in the supply and installation of GEMS fully programmable ECUs for rallying, racing or advanced tuning of road cars. A GEMS ECU provides the ability to tune modern fuel injected and turbo cars to obtain optimum performance for the available fuel and local weather conditions. Some models also include Launch Control, Water Spray Control and Turbo Anti-Lag capabilities.

The most popular applications are for the Mitsubishi Lancer Evolution 1,2,3,4,5,6,7 and 8 and for the Subaru Sti WRX models.
