Description
Part Number: 557-201
Introducing the newest development from the Holley EFI engineering team, our EFI high flow dual port boost control kit featuring two solenoids. This kit contains a set of pre-installed high flow solenoids, which feature a dual O-ring sealing design, preventing any boost leaks out of the manifold. The solenoids are driven by Pulse Width Modulated (PWM) outputs of the ECU.
Features and Benefits
⢠Black anodized billet dual port manifold with built in mounting provisions
⢠Two 1/4ā NPT push-lock fittings for easy plumbing and installation
⢠Two pre-terminated connectors simply plug into the solenoids and extra pins into Holley EFI ECU connectors
⢠Proprietary design to flows nearly 40% more than comparable designs and up to 90% more than conventional 3-port boost control solenoids
When selecting solenoid configuration in the Holley EFI software, use the Dual Holley drop down selection. It is not advised 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.
