Link ECU Boost Control Solenoid

Link 3-Port Boost Control Solenoid

The Link 3-Port Boost Control Solenoid provides precise electronic boost control for a wide range of turbocharged applications.

It is suitable for both internal and external wastegates, and can be used with single or multiple wastegate setups. When configured correctly, it allows boost levels to be increased above the base wastegate spring pressure while giving the ECU control over the boost curve.

Suitable Applications

Compatible with:

• All Link ECUs

• Internal wastegates

• External wastegates

• Single wastegate setups

• Multiple wastegate setups using a T-piece

• Open Loop Boost Control

• Closed Loop Boost Control

For more complex boost control setups, including some 2-port wastegate arrangements, a 4-Port Boost Control Solenoid may be more suitable.

Installation Requirements

The solenoid requires:

• Spare ECU Auxiliary Output switched to ground

• 12V ignition-switched power supply

• MAP sensor

• Open Loop or Closed Loop Boost Control configured in the ECU

No separate standalone boost controller is required.

Key Features

• 3-port electronic boost control solenoid

• MAC 35 Series

• Compatible with internal and external wastegates

• Suitable for single or multiple wastegate configurations

• Fast and consistent response

• High shifting force

• Short-stroke, high-flow design

• Balanced poppet design

• Resistant to pressure variation

• Rugged construction

• Long operational life

Boost Control

The solenoid can be used with:

• Open Loop Boost Control

• Closed Loop Boost Control

Depending on the application and wastegate setup, boost can typically be increased to around 2 to 3 times the base wastegate spring pressure.
