Timing curves for MSD Digital E-Curve Distributor?

Just for the record, you have your vacuum advanced hooked to manifold vacuum and not ported vacuum or it wouldn't add timing at an idle.
Once again you are correct.
Manifold vacuum
I have not checked how much the vac advance adds at idle, probably 10 or more degrees, sure does make it idle nice.
My distributor was built/curved by FBO and they stated non ported full manifold vacuum
