Put simply, you set a minimum opening time (turn on time) for the 2nd bank
and an RPM dependant bank split curve. When the computed time for the 2nd
bank, according to current load and bank split is equal or above the turn on
time, the pulse is split according to the split curve at the current speed
point and both banks inject their share of the fuel. There is also a turn
off time which cuts the 2nd bank when its time would fall below the
specified limit. Say your bank split is 50/50 over all the RPM range, turn
on 2ms, turn off 1.7ms, you'll use the 1st bank up to 3.99ms then split to
2x 2.0ms, but you could also choose to use only the 2nd bank from a certain
point, or anything you like. This will accommodate paired (twin) injectors
just as well as high/low injectors. There is many other parameters like a
temporary enrichment with variable decay, bank scale and more.
