Automotive Engine Management Systems

GEMS has been designing and building specialist engine management systems since 1985. Our ECU range covers competition automotive, motorsport and bespoke applications - and where standard products don’t meet the requirement, we develop custom solutions. All GEMS ECUs are fully configurable using GWv4 software.

All GEMS ECUs require GWv4 software for calibration.
