Default Scratch Built Ignition???

on the tim-6 with hall effect sensor the dwell time is determined by how long the magnet stays under the sensor. this is the major drawback to this ignition. i've seen a similar system adapted to a motorcycle useing 2 sensors, one opened the current to coil and the other one closed the current, this gave an adjustable dwell angle. the only advantage to the single sensor that i can see might be low current draw. these systems were originally designed to be used with points where dwell angle would not be a problem.
