sorry dude, but you couldn't be more wrong. the ecu has nothing to do with boost period.
the boost controller doesn't even wire into the ecu. anyways, the boost controller controls the actuator. it reads the boost pressure and then tells the actuator to open based on the desired boost pressure. it does this through the use of a boost control solenoid. it intercepts the boost pressure (usually from the cold pipe or however you have it plumbed) and when the desired boost pressure is close it starts sending the pressure to the actuator on the wastegate which opens it.
