[primary] trigger setup image from Megatune

[Image] of transition trigger being used for a 60-2 setup. Its not 100%, but it does work.

With this setup I found ingition events occuring on (0 degree advance makes math easier)

Tooth 14 and tooth 46 thats 32 teeth apart I am going out on a limb here and we'd like this 30 teeth apart :-) otherwise there is a 12d difference between spark events and crankshaft rotation

Moment of Clarity

So to setup the primary trigger events..

Measure the angle of the crankshaft in reference to TDC that the missing teeth cross the VR sensor.

* In a VAG 60-2 wheel that is 90d btdc

Then determine if that event is between 60degrees and Max desired ignition advance, or alternatively set it to 60 degrees

* In a VAG 60-2 wheel that would be 90d = 15 teeth, 60d = 10 teeth

** 15-10 = 5: the primary trigger event occurs on the 5th tooth.

** clarification do we count the missing teeth for this calculation? It does not look like it on the scope image.
