The exclusive DMC fuel map optimizes air/fuel ratio at all RPM’s for maximized throttle response and horsepower. The DMC EFI Control unit offers more advanced settings than any other brand. Unlike other brands, the DMC EFI Unit features 1/2 stage fuel settings as well as partial and full throttle crossover settings for precision adjustability. Installs in minutes and plugs directly into the OEM wiring harness between the ignition and fuel injection control of the engine’s fuel management system. This unit is precisely mapped to make your modified engine come alive. Three simple buttons on the faceplate allow easy adjustments to move the fuel curve richer or leaner in each area of the map. And, advanced engineering eliminates the need for complicated computer programs and interfaces. Everything is controlled directly on the EFI Control Module!
