Holley Fuel Injection Parts Boost Control Solenoid
Holley boost control solenoids are designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. They're driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised NOT to use the PWM+ outputs on a Holley HP ECU, but rather use the PWM- outputs. If you have a Holley Dominator ECU, use either the PWM- outputs or a PWM+ output on the J2B connector.
