We recently installed my emerald management in my track car but I have now found what I believe to be a boost control valve of some sort in my many boxes of bits (pic below) as I remember removing it from the previous car and I know it was plumbed in.
My questions are I don’t remember any additional switches in the car that would control the valve so would it just be 1 setting that’s run straight to the ecu? I have the wiring diagram for the ecu and it shows where the boost controller was connected but I don’t know if it went straight to the boost valve or if there would have been a switch or something. I intend on running some sort of 2 stage boost so don’t know if this will or would do the job.
On the ports it has NC, NO, COM and I know only the turbo and actuator where connected to 2 of these.
Any help would be appreciated.
