Automotive Engine Management Systems

GEMS has been designing and building competition automotive engine management systems since 1985. Because of GEMS ongoing policy of developing products in response to the needs of its customers, and in many cases in close collaboration with its customers, the range of EMS products available are now highly flexible and covers all ECU requirements.
