Logic doesnt compute on what msd told you. He must think it is locked advance. Hes saying rotor phase with the cap can be alerted with part(s), yet mech advance which moves said parts does not. Cant reconcile those two concepts.
It does not change with mechanical advance, because all mechanical advance does is change the relationship between the engine and the rotor. The rotor to reluctor relationship does not change, so the rotor phasing doesn't change either.
I figured that video was displaying a timing retard active through an ignition box, glad it was confirmed. It is electronically changing when the coil is commanded vs. the reluctor (and rotor) position.
