COP Ignition Development

Nice work.
About the 'why not a crank trigger'... On my seasoned 318, in which I installed a new timing chain a few years ago, I can measure upto 5 degrees of retard when quickly revving the engine from idle.
Adding a collar on the distributor did nothing. Have had the distributor apart a number of times, no issues there. Which let me to think it's the camshaft that wanders forward and back during engine acceleration.
Was very noticable with a timing light.
