My buddy has a 2001 Chrysler car and its roof display has all the features mine has and also has current MPG. My truck has just the average. Is there a MOD or some sort of reprogram to get the current as well as average MPG?

 

I don't mean to rain on your parade, but the overhead lies 95% of the time. Hand-calculating your mileage is the only reliable way.

 

I know this, but it still would be nice to see the current as opposed to the average. My VW lies too....they all do.

 

Mines not that far off at all...maybe .5- 1.0 MPG....

 

Resetting the average gives you the current for a short time...so if you're on the freeway hit the rest button and you'll get your current mpg. Mine usually averages 16 mpg mixed but if i'm on the freeway i'll reset it and it'll instantly go to 23+. My overhead seems to be pretty accurate....+-5%

 

if you want to know the current MPG
without resetting the Average
you can watch how many miles
to click over 1 gallon of gasoline.

For example,
What I mean is
if you click the buttons and find that
the mileage since reset is 210
and the gallons is 12.2
then stay on gallons until it goes to 13.2
and then go back to mileage....
if it has gone up...to say 230 miles
then your current MPG is
(230-210)/(13.2-12.2)
or simply
20/1.0
or 20 MPG

By watching how many miles you go on 1 gallon
you get a easy to figure "current" MPG

 

thanks for all the info on this question, but i really just want to look up and see what the currenty mpg is. is there a way to reflash the computer to get this? if the chrylser has this, whey cant my truck? please help!!

 

What year is your truck? Mine has it....I thought all the 02+ Dodges did.

 

I have an 04 QC HEMI 4x4 with the off road pkg. is this something that i can go to the dealer and get installed via a program?

 

My 07 doesn't have it, just average economy, not instant...
