Electronic Engine Control System (EECS)

The EECS is an electronic, microprocessor controlled system that continuously monitors and adjusts
ignition timing, fuel injection timing, and fuel mixture based on operating conditions. The EECS
eliminates the need for magnetos and manual fuel/air mixture. Figure 2 shows the EECS integrated
controls.
The EECS connects engine hardware with electronic controls to replace mechanical control systems
and enables single lever engine control.
