For Boost Control
Part Number: 557-200
Our 3 port boost control solenoid is designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. The solenoid is driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised not to use the PWM+ outputs on an HP ECU, but rather use the PWM- Outputs. If you have a Dominator ECU, either use the PWM- outputs, or use a PWM+ output on the J2B connector.
Features and Benefits
• 3 port
• For boost control
• Used with Dominator and HP
• Includes (1) solenoid, (1) ECU pigtail harness with factory crimped ECU pin, (3) 3/16" barb fittings, (1) 1/8" NPT plug, (1) sintered brass muffler. and (1) spare ECU pin for modified harness lengths
Solenoid is driven directly from a Pulse Width Modulated (PWM) ECU output.
