Yeah me and a friend hooked up a cobalt nitrous pressure gauge to my bottle. The gauge illuminates and sweeps when you turn the car on and everything. The only problem is: it doesnt show the nitrous pressure lol. Here are some pics of what the sensor looks like installed. Any help or suggestions are greatly appricated.

 

The obvious question is did you have the bottle valve open so the sending unit sensed the pressure? Kinda obvious but have to ask

I would move the Bottle heater pressure switch to the bottle, on the port opposite the mechanical gauge you have. The reason being, if the valve is closed, the pressure switch is not reading the bottle pressure until the valve is open. Lets say your heater is accidently left on or turned on with the valve closed, the heater is gonna cook the bottle til it can't get any hotter or til the rupture disk burst, reason being the heater switch "thought" there was no pressure because the bottle valve was closed.

Naturally if you do move it, do it when the bottle is empty. Those ports are always pressurized when the bottle is filled.



The instructions I sent you were for a dynotune pressure gauge, that is an autometer gauge. Did you hook it up the way autometer said to?

Thats odd.

 

I did have the bottle completely open. I dont know what it could be. Also, beer where did you get that elbow for your gauge so that you can see it better?
