I connected the timing light and started the engine with the one working original DSAI ignition module, and sure enough, the ignition did advance a few degrees between idle and full throttle. Nothing like the centrifugal and vacuum advance you see in a 1965 Dodge 225 slant six, but maybe five or ten degrees. <br /><br />Then, I replaced the DSAI modules with the new MDI conversion kit, and re-tested. The spark advance seems to be about the same. I don't know how it works, because I can't find any documentation or schematics.

Then I'll compare that to the new MDI modules, and see what they do. Karl Uppianohttps://www.blogger.com/profile/04857875236624845139noreply@blogger.com
