    Beer do you have the scaling on the autometer Fuel pressure sending unit??? So I can log my standalone....

    Also Can I use my AC wiring since its a 0-5v... I ditched the AC long time ago.. If Im not mistaken its 0-5v..

    So I could use the V1 to log the NOS pressure since thats in the car and the AC wiring since thats near my Nitro Dave's standalone.... or vice versa

    Just need custom PID's......

    Pressure = (Voltage-.5)*400 seems to work for the 1600 PSI gauge.

    Autometer tech service on the 2240

    The wiring for the 2240/2246 is Gray= +5VDC, Black= Ground and the Purple= Signal. The 2240 sender spec are as follows...


    PSI volts
    0 0.5
    800 2.5
    1600 4.5
