Follow up test with a CDI ignition

I like that you used a point distributor this time. Very cool. It's also a diferent type of trigger signal. I think similar to a square wave pattern of a digital signal. I'm not saying you conclusion is wrong that this Mallory box has less retard than the hirev 7500 box. But you have introduced another varible by using the points distributor in place of the Chrysler electronic distributor. Just for the sake of arguement what if you triggered the Mallory box with the Chrysler electronic distributor and it retarded like it did with the hirev 7500 box? Is this a test you can do?
