5. SC E system interfaces aircraft magnetos with electronic multiple sparking technology ignition system When active the G3i module controls the magneto to produce a series of sparks during each firing event which lasts for 20 of crankshaft rotation to insure complete combustion The result is reduced variations in burn times and therefore more engine power better throttle response easier starting and better fuel economy The G3i Series SC E module combines the 1 magneto and 1 E PMAG ignition system with all the benefits of a dual synchronized variable timing electronic controlled ignition system with still retaining 1 magneto for back up When the G3i SC E module 15 activated it receives the signals from the existing E PMAG primary side of the ignition The E PMAG timing signal is picked up by the G3i SC E module and tracks this information processes it and sends primary spark energy to excite the left magneto coil to fire in perfect synchronization with the E PMAG s variable timing advance curve When the G3i SC E system is turned off or looses its 12 volt power the G3i SC E module switches to default no required power and disconnects internally from the E PMAG s primary signals and reverts the magneto back to its normal original configuration In case of G3i SC E El failure the G3i SC E system is turned off to revert back to magneto mode In case of an electronic failure and no output from the E PMAG the G3i SC E will run the left mag
