This can be changed in the OEM Setup of the radio. To get there: Setup > AV > OEM Setup > Vehicle Feature Settings

What radio are you using? Gauges are able to be changed on most radios by push/hold on the gauge and it'll pull up the menu. If that doesn't work on your model, Vehicle settings > Gauges.

The fuel tank size is configurable, you'd just go into that same menu and adjust it there.

I'm using the Kenwood DDX9906xr. i've tried the settings area and while i am able to change the size of the tank right now i'm sitting at half and it says 87%. I have a 18.5 gallon tank. I've tried pressing on the gauge and holding it but all i does it go from a regular arrow to a blue trace arrow.

Correct- tapping the face of the gauge just changes its appearance. Pressing and holding should allow you to re-assign the gauge. To change any kind of gauges settings, I recommend going into the OEM setup menu of the radio (Setup > AV > OEM Setup > Vehicle Feature Settings). You'll have a lot more options there.

As far as fuel level goes, it is just being reported by the vehicle's OBD2 in a percentage. In some cases, changing the fuel tank size can impact this, but often times the vehicle is just not reporting the percentage correctly.

Unfortunately, no. We're simply taking the information the vehicle is sending and populating it. If one of the parameters is slightly off, this can cause the calculation to be skewed. There is not a way to remedy this.

Unfortunately, I ran into this same issue in spring of 2018 with my Maestro in my 2010 Challenger. I was told that the Maestro calculates fuel usage based on diagnostic info (injector cycles, etc) and doesn't read the Chrysler OEM registers that report fuel tank percentage. The fuel gauge data is available on the bus, and that's what our gauge clusters use, but programming brand-specific queries that can be flashed into the Maestro via the vehicle-specific process that we already use, isn't something they're able to work on. Or at least that's what I was told, back then.

By the way, the "Chrysler enhanced" PIDs for this are:
252 "FLVLP" "Fuel Level Percent" "%" 0
or
251 "FLVL" "Fuel Level" "gallons" 0

I'm reasonably sure this same type of info is available on my wife's Tundra since there's an app for it on the factory head unit.
