overhead console says 22 mpg . I only get 15 -16 on paper. Can i fix it?
I have 35x13.50x20 a 3.5 inch lift and smart

 

I dont hink you can...better off hand calc...the overhead being off is quite annoying

 

Set it to something else like the compass and temperature..

 

Mine used to be off by 1 or 2 miles per gallon. After putting a new program on it, it got up to 28mpg and I was averaging 19. I just hand calc now since its seems to be all over the place now.

 

Unplug it, that is the only way that I know to fix it.

 

My Dodge is off by 3 mpg everytime, I don't expect it to be accurate with my mods. My VW Jetta is always off 12-15

 

mine is the same way, three mpg off. It looks nice when you show it to your friends that have never road in a diesel truck before! " holy crap you get 19 mpg!" What do you say to that besides YEP!! LOL!!!

 

Mines off 3 also but in the other direction all my buddies get in and say "**** how can you afford to drive this getting 13mpgs"

 

I'm pretty bummed when mine reads anything less than 22mpg. Lucky for me, mine's been accurate to within 1/2 MPG since I got it.

 

Overhead console thing is pretty much useless. Gimmick at best hell the temperature isn't even accurate on mine. Hand calculation for fuel mileage is the only way to be sure.

 

My read out just started working when I started hypermiling. it says I'm getting 16.1 mpg.s average towing a 5000# trailer about half on interstate half around town. wich is way better than I was getting when drove it like I stole it. and before I would calc. it by hand and was getting about 11mpg.s and my read out said 12.5 but now I hand calc about the same as the computer. go figure. but the best thing is now when I get to where I'm going, I'm much calmer and all those people that passed me are still getting poor milage. and I just smile.

 

Gently remove it being carful not to mess up the factory plugs and connections. Get a soft rag and wrap it up. Place it on the ground and smash the snot out of it with a sledge. Works on every 3rd gen overhead

 

lol
Yes, very important not to damage it by removing it before you smash the crap out of it!

Mine's never told the truth, especially when I run Crazy Larry which always displays about 5 MPG more than actual...

 

Best suggestion yet right there...
