Lastly, the motor still runs fine as far as I can tell, so I don't think anything was damaged as a result. Having said that, the motor does have forged pistons.
a bad module CANNOT advance timing, though it can slightly retard it.
I'm wondering if you either have a bad advance mechanism, or just don't know how to set timing. you said "locked out" and locked out is locked out, that means 34º at idle, at redline, and at every point in between.
