    Does any one know the difference between the ug volts and ecm volts on the ultragauge? Was looking to monitor my battery and found these 2.

    Probably the voltage the ug sees directly, and the voltage the ecm reports.

    I expect they will read about the same.

    BTW, UG Temp is the temperature the UltraGauge senses, so basically a cab temp.
