NE and G Sensor
Can someone explain how these two crank trigger sensors on the front cover work, which one controls the leading and which one is the trailing.

The N and G signals go into the ECU so the the ECU 'knows' the crank position of the engine, (i.e. 90 degrees). The G happens once per rotation basically and index. The N happens every 60 degrees of rotation. The ECU resets the degree counter when the G pulse, (index) happens and then increments to the next 60 degrees for each N pulse.
0 - 60 - 120 - 180 - 240 - 300 - 360 - 420 - 480 - 540 - 600 - 660 - 720/0
Being a 4 cycle engine there are 720 degrees to keep track of.
So with the ECU knowing the engine position it can then fire the leading / trailing coils at the correct engine position.

A two rotor should only need to keep track of 360º.
At 0º it fires the one rotor, and at 180º it fires the other rotor.
720º is for a four cycle piston engine.

But... for every full rotation of a rotor, the crank shaft has rotated 3 times. So, you would need to keep track of more than a single rotation.
I would like to know what NE and G stand for. I have looked in the manual several times with no luck.
