DIY Electric Boost Controller.
 

Appearently the DSM boy's hav been doing this for a while. I found this while trolling a DSM forum. It's a way to use 2 or more MBC's(Manual Boost Controller's) from your cockpit via a selectable switch. Anyways, credit goes to www.taboospeedshop.com

-- A 3-way valve is being used to switch between two MBCs set at different boost levels (Low and High). A similar 3-stage unit can be easily built with 4-way valve and 3 MBCs or bleed solenoid incorporated to the WGA line.

The ARO version of the valve needed can be found here

-- This is the basic Cheap-man Profec design. The boost signal goes straight to the WGA through the MBC with both solenoids closed (Low boost) or is bled off through only one (Mid boost) or both (High boost) solenoids to the atmosphere. The Mid and High boost levels can be fine tuned by restricting the outlets of the solenoids by bleeders with different-sized holes or adjustable needle valves.
