Using fuel pump cam lobe for a trigger

Too fast was l.

But yeah, this is nice solution for a cam trigger on B230. Air gap is little pain to get right, so adjustable (w threads) sensor is more forgiving with design.

I made first prototype of cam with angle grinder. Second one was made first by milling and then turning the cam to get off-centric off. With that one air gap was too big and small adjustment of braket was needed.

This is for VW air-cooled engines, but suits also B20 and B30
Similar to Compu-Fire DIS trigger for VW or most any 4 cyl Bosch distributor. I had that system adapted to B21
