This page shows you some of the basic SDS components, sizes and a few of the programmer windows for informational purposes

This is the dual ECU which needs to be mounted in the cabin area. Size is 8.5 X 3.875 X 1.75 inches. This unit has dual circuit boards for redundancy and runs the fuel injection and ignition.

This is the dual fuel pump module, usually mounted horizontally on the floor of the aircraft. Size is 11 X 4 X 1.75 inches. Usually on one pump is used in flight. Internal check valves in the pump outlets prevent backflow when only one pump is on.

4 cylinder coil pack and mount. These replace the magnetos. Most dual plug aircraft engines will use 2 of these units, one for each set of spark plugs. They mount into the original magneto holes. Alternate mounts are available.

Thread-in injector mounts screw into the original 1/8NPT injector holes in the tops of the cylinders. Plumb to the fuel block with -3 braided hoses supplied with the kit.

Mixture knob replaces the conventional mixture control. Primarily used for leaning the engine in cruise. We recommend this be mounted high in the panel so it cannot be easily bumped.

Design1 programmer is standard on EM-6 aviation systems. 6.25 X 1.47 shape fits nicely in the radio stack, integrates best with glass panels.

Optional round programmer mounts into a standard 3 1/8 panel hole. Allows you to program all aspects of the EFI and ignition systems. Dimmable backlit display for night flying.
