    Programable Fuel Pump Voltage Pressure

    This is a cool idea from MSD designed for increasing voltage to fuel pump during boost. Wonder if it could increase voltage the other way? During drop in vacuum?

    Re: Programable Fuel Pump Voltage Pressure

    Hmmm, Maybe what is done is to control a 6 VDC fuel pump with Pulse Width Modulation (PWM)? I used to build robots with permanent magnet DC motors , and I often used 24 VDC on a 12 VDC motor with a PWM motor controller.
