Any way to adjust MPG calculation/display?

Right, the MAF will measure the airflow and the computer determines the injector pulse width from this. If they are all calibrated properly it should work well.

 

The fact that I notice my fuel trims are pulling fuel (being there is a rich condition) I am curious if once tuned properly the computer may be more accurate.

So, got a chance today to take a road trip and the conditions were perfect.  Here's 'proof' that 24MPG is absolutely doable in these trucks under the right conditions.

 

Cruise set at 70, no wind to an ever so slight tail wind, about 90 degrees outside.  3.42 rear.  Video was before we stopped to fill up.  Pictures are after we filled up for the remaining 180 miles of the trip.

Not that I doubt it, but how does your DIC match vs actual fill up numbers.

Usually off by 1 to 1.5 on my 2014. (DIC says 20, actual would be 18.5 - 19)  2018 is looking like it will be the same so far.
