well that seems conclusive enough paul great post. I have to say that a picture speaks a thousand words and saves viewers speculating .
I must admit I am finding this issue a real struggle to follow at the moment as I am suffering with Vertigo . I read and reread Grizld1's post last night and still couldn't follow it . its a complicated association to keep in correct relationship in your mind when you can't see straight or concentrate properly.
If the crank and cam indexing is correct then the only other potential issues must be the Fully advanced mark or the Boyer module is faulty.
Once the Boyer pcb is clamped in place there is very little retard/ advance adjustment allowed as the slots are short.
If the crank is set at the fully advanced position and the camshaft index mark is vertical.... then clamping the Boyer magnetic rotor to the camshaft with the white dot visible in the pcb hole should theoretically get the timing very close to being spot on.
The pre-programmed Boyer chip adjusts the advance and retard according to the rpm of the camshaft and produces a spark at the correct time by its register of the relative positions of the rotor magnets and pcb coils in relation to the cam and crankshafts fully advanced position
It should only require a very small adjustment of the pcb plate to tweak the timing with a strobe.
The position of the camshaft relative to the fully advanced position is sensed by the position of the pcb coils in relation to the rotor magnets and that data is transmitted to the Boyer module. So if the fully advanced timing mark is correctly marked ,it does suggest that there is something wrong with the Boyer module or the processor rather than anything to do with the magnetic rotor, pcb board coils or the position of white dots
