Ok, long story short, I bought a used Snow Stage 3MPG MAX, and had to replace the controller.
So now, I have a brand new controller, instructions etc.
I hook up the wiring as per the instruction manual, BUT, I did not hook up the second stage solenoid, just the first stage. (I wanted to cool down the temps as I drove to work, and gain some mpg.)
Set the pump to start injecting at 5 psi, and max out at 30 psi. Did not seem to help at all. The display would cycle between the "Snow Performance" screen, and the Boost, EGT, Injection rate screen, indicating that it was injecting at a 40% rate while I was driving.
After 3 hours of driving...twice, so 6 hours of driving, I check the tank...it's still full. WTF???
Hook up an air line to the boost line, and simulated 50 psi boost, this sent the injection rate to 100%, and the "Power Mode" to come on as well.
Checked for power at the pump, I only got 6.7 vdc. (Fluke 87)
Pull a battery off the shelf, measure 12.7 vdc, and hooked the pump and solenoid to it...works fine.
What is wrong with the brand new controller? All connections were soldered, and shrink wrapped.
I have the pump, and first solenoid hooked to the "WHITE" wire from the controller, while the "Green" second stage "Power Mode" wire is bent back and taped until I install the second stage.
Thinking that maybe the controller was pulling too many amps from the fuse box, I ran a temporary wire straight from the battery "+" to the inline fuse, then to the rocker switch, and tried it again...same output from the controller.
.....Anyone???
