Manifold Vacuum Advance what am I not getting?
Works fantastic by the way! There is no way I could have tuned my motor this well with springs. I have the wrong torque converter that is too tight and a high cammed motor. I was getting significant drop in rpm in gear with my msd set up. I used this programable distributor to increase timing just after crank to enable lowering of my idle out of gear. So just below 700 rpm then lower timing just after 900. This keeps the motor running in gear at almost the same rpm as out of gear. Simply amazing. Heres my current map.
