I'm sure AZRR has something figured out. He might be using an FJO injector driver. He's also got gobs of injector capacity so will never probably have to run the injectors anywhere close to 100% duty.
Not that anyone would probably care (electronics are pretty boring stuff to everybody but me), but typically output current capability of a switching circuit such as an injector driver is completely dependent on proper heat-sinking and transistor/FET Ron resistance. (i.e. completely a thermal issue) If anybody has a picture of the internal heatsinks of the PFC injector drivers and their part number, I can compute close to exactly the ambient temperature at which point the silicon will self-destruct at a given duty-cycle/RPM.
