To control Boost using an engine management system you need a solenoid for the ECU to control. This solenoid controls how much air is allowed through to the boost reference nipple on the wastegate therefore controlling the boost level. Without a boost control solenoid the ECU cannot control boost.This Boost Control Solenoid is universal and can be wired in for use with any EMS.
