Holley 3 Port Boost Control Solenoid, Part Number: 557-200


Utilize the built in boost control programming in the HP and Dominator ECUs, to have complete control over your boost levels without additional control systems. To complete the installation, Holley is offering boost control solenoids, specifically designed for use with the Holley ECUs. The solenoids can be driven from any of the pilse width modulated outputs on either ECU, and are designed specifically for the boost control strategies designed within the ECU.


Holley's 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. For complete mechanical and electrical installation of this solenoid, as well as tuning, refer to Holley Instruction.
