No. Ive had motors with some cylinders that you couldn't give enough timing to make them detonate and other cylinders that you couldn't take enough out to keep them from detonating. A lot of times I've ended up with 2 different heat range plugs in a motor. If I had the capability ignition running I'd run different timing in each cylinder.

ring seal and not enough breather area cause this on boosted engines, time for a rebuild and would suggest 5/8 hoses from each valve cover to a large puke tank or 2 small ones(I run this setup). next need to tune with a wide band, pissing in the wind any other way and you could be killing it and never know by the way it runs

I've wondered why nobody makes a totally adjustable ignition, or why I've never heard of it. In the Harley world you run 2 programmable, different curves and switch between based on an adjustable vacuum switch. It also allows to advance or retard one of the cylinders and withhold spark for X revs on startup.
Seems like a doable deal for 8 cylinders also.
