The ratio of positive to negative “duty cycles” determines motor speed. To illustrate, a 30% positive duty cycle indicates that the current to the motor is being switched on 30% of the time and off 70% of the time. A 50% duty cycle indicates the current to the motor is being switched on and off in equal time.

The fuel pump controller does this by rapidly turning the power on and off (square wave pulse width modulation). The duty cycle reported is the Fuel pump duty cycle problem(Fixed check post #12) Leaning out when Fuel Pump Duty cycle at 66% Fuel pump duty cycle Fuel Pump Duty Cycle - Not Switching

The ratio of “on to off time” is called the duty cycle. The duty cycle is the fraction of one period in which the voltage is on compared to the off time. A constant 12

Like some have already said you need to keep your FPDC under 85-90% at WOT full load conditions. Most have no idea their duty cycle is too What should fuel pump duty cycle be? Fuel pump duty cycle questions.. Fuel pump duty cycle fuel pump duty cycle?
