Can a logic module (or SMEC) be made to fire each batch twice per cycle. This engine has siamesed intake ports and uses 2 injectors to feed it. The duty cycle needs to be split into 2 equally spaced pulses of about 25 to 30 percent. Can this be done? Here's what I've learned about this:

The SMEC anyway already does fire each bank once every revolution. Or, twice per cycle. Whichever way you want to look at it.

So every cylinder actually gets 2 shots of fuel?

What I have not figured out is, how it splits the fuel PW into 2. I can't really even find where the 49152 uSec max injector duty cycle comes from. But, for sure, it fires one bank or the other every distributor interrupt (ie, every blade event).
