I got an interesting response on the megasquirt forums regarding ignition triggering. I was planning on locking my stock dizzy and installing a pertronix hall sensor unit in there. Has anyone tried this?

VR and Hall also make no contact.
VR = variable reluctor. It's a coil of wire wrapping a magnet that, when a ferrous part moves near it, sets up a current in the coil. On a 'scope' this looks like a sine wave where the peak is the part of the tooth that's closest to the sensor, and the trough is the valley between the teeth. This is, incidentally, the same way an electric guitar pickup works. Hall = Hall Effect, which is a magnetically sensitive transistor. When a magnet passes by, the transistor switches. In both cases, there's an air gap between the sensor at the teeth on the wheel. The sensor never touches the wheel. |
