COP Ignition Development

I installed an optical sensor board today and did the first test using a portable drill to spin the distributor. I used the sensor PCB that I designed for VW engines with modifications. Only one sensor installed, and the board needed to be offset, so it was changed for that.

A window was cut into one tab for the cylinder sync reference. I drilled a hole and filed it square. The detection means is flexible.

I made a new longer coupler for the shutter wheel, it extends to the top of nylon on the 5/16" distributor shaft. I started with a part from by VW conversion. They both have the same ID size.

Shown below is the distributor timing at if was set to trigger for #1 cylinder, the trailing edge of tab following sync tab is aligned with center of opto sensor. This would be done with crank set to desired base timing.

The following is a capture of the distributor signal on cyl2, and the rest of the cylinders.
