Fuel injected bikes like the '03 ZX-6R, '01-up Suzukis, etc, have a computer that controls the timing and injection shot. The Power Commander (PC) is a black box that allows you to alter the program (map) to accomodate modification such as exhaust system changes. It is analagous to rejetting the carbs on a carburated bike.
