FWIW I myself could run the valve on its own but I choose not to do so, rather trusting Richards already worked it out as a package that works. I use his complete kits > see here,

integrated into my own Syvecs/LR ECU packages, they work and are 100% reliable, no stress, no need to do something where the hard work has already been done.
The opportunity cost to me means its just not worth stuffing around.
I can verify after using many of the kits that they do work as stated and are very repeatable, and dependable, to date never had a failure and more importantly the accuracy for fuel and knock control with increased performance is second to no one else offering (WI systems).
Great job Richard
