I'm going to be working on a rotary soon, and staged injection is extremely common in rotaries.
Staged injection uses primary injectors operating all the time and secondary injectors which operate only at higher load/rpm. Both sets of injectors are controlled by the main fuel table, however the percentage of the total fuel delivered by each injector set is controlled by the Secondary Injection Staging Table. The secondary injectors may be brought on at any stage after the lockout conditions are met by entering non-zero numbers into the Secondary Injection table.
There should be
A "percent injection" table, maybe 6x6, that decides how much injection is done by the second stage (0% meaning the primary set of injectors is used, 50% is both sets of injectors used to deliver the fuel equally (so, assuming 100mg of fuel is needed, the first set would inject 50mg, and so would the second), and 100% is all of the fuel being delivered by the secondary set.
This typically uses a clone of the primary injector settings (but now called "Secondary",) and the split ratio table.
