The most efficient way to do this is to have a cam synch signal so you can fire each of the 6 circuits in the firing order but not sure if Chris has or is planning to go full sequential. Instead you can go wasted spark and batch injection but....

I'm not sure how many spark outputs the MS3X has but seems like they often require an external ignitor to put the system together. A single ignition output will often be used to fire 2 coils at once in a wasted spark setup, with the external ignitors used to actually fire the coils.

I'd be using the CBR coils in my twin plug setup but they would draw too much current to fire two per ignition output. Instead each of my 6 ignition outputs will fire two smart coils, one top, and one bottom, for each cylinder.

I've recently spoken with Chris and he advised he will be going full sequential ignition and injection...like he did on the MS3X.
