DIC fuel data inaccuracies

I find that my Fuel Used in the Trip-o-meter display is really accurate to what fuel I have used. It's rarely off by more than 1/2 gallon when I fuel up.

my first fillup ever my DIC said 15 miles till empty and 36 gallons used. I put 36.5 gallons in.

hello, I also find a strange difference between the DIC and what my edge insigt cts shows. For instance at 100kmh -around 60mph- DIC shows 9 l/100km and the edge shows 6 l/100km. Of course the edge seems very optimistic as an F350 6.7 is not a Prius. Anyway 9 l/100km is not so bad but I can't explain the difference as both are picking their information from the very same source. Edge being plugged to the OBDII. Any ideas? Thanks.

Do you have your gear ratio and tire size set correctly with the edge? If you have 4.10's and 33" tires but you edge thinks you have 3.55's and 37" tires then you're going to be way off! Hope this helps.

Edge's computer allows me to enter tire size but not gear ratio. Anyway it's more for the speedometer to be correct in case you don't run stock tyres. I tried to put my stock size and it changed nothing. Again it's strange as both DIC and Edge are linked to the engine's computer and its sensors. But give different results...
Thanks for your help anyway,
