Manifold Vacuum Advance what am I not getting?

Right. You end up with an inverted curve.

I just thought of the most simple fix that will work.

Get yourself a Progression distributor and use that.

IIRC, you can put any digital curve in it you want.

That’s what I would do in your case. You can change the tune up with your phone.

Yeah, replace a perfectly reliable analog system with a digital system controlled by your phone. In a street car. Yep, that is exactly what I would not do. :thumbsup:
