I know the UltraGauge will not calculate fuel used accurately due to the way LR measures something in the MAF..

So has anyone found a reasonably priced gauge that will work?
(I know, if i have to worry about the fuel, I should not be driving this thing...)
Thanks

 

A gauge for mpg??
Here ya go!!

I've never seen any mpg calculator, factory or aftermarket, that was completely accurate.
Every one I've seen has been 1-2 mpg over the actual mpg.
Easiest way is to fill up, let the handle shut of the gas(don't top it off), drive where ever and burn 1/4 - 1/2 a tank, fill back up at the same pump, let the handle stop it again, and divide the miles driven by gallons used.
Then be prepared to be disapointed, lol.

 

There's the money quote right there!

 

yea .. fur sure.. I know what it is getting but my other car is a 14 touareg with the instant MGP read out. That being real time, I have changed driving habits and get better mpg's. was hoping to create the same feedback in the "beast"
oh well,
