I just got a Scan GaugeII hooked up in the Souper Doody, in X Gauge there was were two FICM power level displays available, Main and Logic. I programmed FICM main power "addresss" and I get these RIDICULOUSLY low voltage numbers, as in less than 10 volts. Please don't do the FICM test rant, my truck runs GREAT and I KNOW what a bad FICM runs like. MDUB is still trying to fix my old one, it was that banged up.

Did I program in the wrong one? Any inputs from Scan GaugeII users?

 

Probably just the wrong FICM input karl...

and yeah, your old FICM is fubar. Still trying to wrap my head around that one.

 

 

Found it! I had the wrong "address" on the Scan Guage, my FICM reads 48.5 and sometimes 49v.
