So based on that picture wedgeman provided, the painless system replaced the cam wheel with a shutter wheel for the halls sensor.

Sorry, was to lazy to pull it out this weekend. Feets helped me move 8 cubic yards of rock on saturday, and I couldn't move on sunday to mark and pull it.
Might try again this weekend since it is going to rain.

are the BB and Sb shaft diameter and distributer body dimensions the same?
That is, would putting the magnum sensor and this shutter wheel in a bb distributer work?
