I am about to install the “4217” Single Cylinder Programmable Ignition
on my two stroke 50cc moped.
I want to use a magnetic pickup and a home made steel rotor on the crankshaft to trigger the system.

Just so I got it right. When using a magnetic pickup: Should the area before
TDC (“the timing tab”) be a low signal for example 35 degrees and the rest
och the 325 degrees a high signal?

My idea was to make a metal cut out in the rotor to create a low signal
starting 45 degrees before TDC and ending 10 degrees before TDC.

Please look at this image and see if you think this will work:

Thanks in advance!
