Manifold Vacuum Advance what am I not getting?
Yeah and when the "unnecessary" stuff fails, it always affects the necessary. Every single time.
So no one understands that getting the correct curve for something like the OP’s situation is far easier if you can do it digitally.
Especially if you don’t have a dyno and a distributor machine.
I guess not fixing a shitty running engine is a worse option than using a programmable ignition.
Or trying to use MVA to fix it. It’s far easier to do it digitally than working with mechanical advance parts.
I’m looking into a programmable MSA 7 (although I’m not a fan of MSD on many levels there aren’t many choices) because I’m getting near the other end of a mechanical tuneup.
Can I make what I have work? Probably. Will I have to modify the crap out of all of it? Probably.
If I can change the timing curve digitally it will take far less time.
Plus, that ignition offers individual cylinder timing. That looks like a rabbit hole I’d fall down.
To me, for what the OP is doing some type of digital advance curve would be easier than doing it mechanically.
If not, he can hook it to MVA and then do the curve mechanically.
