This is a discussion on "DVC-30 Stage 2 kit problem" within the Technical Questions forums. This forum, and the thread "DVC-30 Stage 2 kit problem "are both part of the General Performance category;
fitted as instructions, controller start set at 2 and full set at 5 we are running at 6psi boost. the green light is not coming on and the pump is not running, when the pump black wire is grounded and the the blue wire is disconected the pump runs continuously
Pumps black should go to the blue wire from the controller
Pumps red wire should go to a ignition on source not 12 volt constant
Red from controller to ignition on
Black from controller to a good, metal to metal ground.
Boost port connected to vac/boost line. Check this line to see if it's actually has a vac to it. And make sure no leaks are in that line. If you have a boost gauge it's simple to just put a t fitting in that line to run the controller.
iv set it up like you said and still not working the only way the pump will work is by wiring it up direct. there must be something wrong with the controller
checked vacuum pipe ok. disconected water meth pipe from manifold put into catch pan connected vacuum pipe from controller to a small compressor via a pressure gauge and the controller would only activate the pump at 15/16 psi any less than this and it would not operate everything else is ok seems to be a too high setting on the pressure switch in the controller
Also check the tip of the boost port and make sure it is not damaged (cracked).
Same thing for the union fitting. If it is still giving you issues give the shop a call about doing a return. These can get damaged in shipping ect.
I have the new universal dvc 30 stage 2 kit with the boost reference port built into the dvc30 controller. Mine is acting the same way. to test I have hooked an air compressor up to the hose that normally is plugged into the carburetor hat that is for boost reference. If I have the start at 2 and max at 5 it does not come on until about 12psi. I have hooked a mechanical boost Gage up to the hose that feeds the dvc30 controller and it is seeing full amount of boost. as I increase pressure the pump speeds up just like it is supposed to do. It is almost like the controller is calibrated incorrectly. if I turn the start and the max all the way up it acts the same only difference is that it starts to come on at 17psi instead of 12psi. I will call tomorrow.

I have a regulator that I put a gage on along with the fittings to connect to the boost reference port and to the compressor hose. I always start with 0 psi and slowly come up to the desired psi. the very first time that I hooked this up to this unit it would not start the pump until I hit just above 10 psi. But I do agree that a bicycle pump would be safer.
Note: Devilsown has informed me that the first batch of these DVC-30 stage 2 Controllers have a programing error and that is why we are having issues with them. So if you need your kit to work under 10 psi it will not.
