Manifold Vacuum Experiment

What people seem to miss is, changing to MVA really doesn't change much. I have the SAME initial timing with MVA with the can unhooked than I did using ported vacuum. The only change is WHEN the can is activated.

When I connected to MV, I had to reduce the static timing to 5* since my happy place is 25* and the can ads an extra 20*. Now I have to rethink my curve because..... When MV drops off when accelerating from idle, the centrifugal is starting from 5* as opposed to 25*.
