This space is for the untested ideas Witch I would like to test and see if they work.
So for now they are just ideas, that needs to be worked out.
I have connected a 4FL servo to a 3MB CDI and that did not worked as planned.
Sadly I don't have a 4FL CDI, but it could be that the signal is differed, also the option off the grey wire needs a investigation.
The 4FL servo circuitboard is designed differently
Comparing the opening curve.
It could be nice for a higher rpm engine
It seems that the rpm is the + signal from capacitor the - signal is for the ypvs unit
