14 volt FICM

ok so I got the dash boss hooked up, and set FICM voltage for one of my parameters, and it is telling me I'm running at 14V

Is it more likely getting a wierd reading, or is my FICM really about to take a big crap? It holds steady at 14

There are a couple of diffrent FICM voltages to look at. There is a relay volt that should be close to battery power, and main internal injector volts that will be your 48. At 14 the truck should not be running or running well. Try looking for another FICM PID

ok thank you I figured it must be something like that, since it is running normal still

You need FICM MAIN VOLTS for your dashboss PID.

Yep worked, dash boss has 3 FICM choices apparently. Main is holding strong at 48-48.5
