nobody asked for this, but here's a comparison of spark sounds, running somewhere around 1000 rpm maybe, settings of max 3 spark, 2ms additional dwell. main dwell at probably around 4ms. these are GM coils with built-in igniters.

multispark sounds cooler.

couple more that nobody asked for, but as i'm testing things for melting, i took a video:
250-ish rpm, cranking mode, 6 cylinder sequential ignition, and injection, but injection is simultaneous while cranking:

and 700-ish rpm running mode, sequential ignition and sequential injection, no longer simultaneous:

this is what multispark looks like on logic analyzer:
1 5 3 6 2 4 firing order
D1 = 36-2 wheel
D2 - D7 = cyl1-6 ign
maximum 3 extra spark
this is about 1000 rpm, main dwell is 4.2ms
