I'm just wondering if anyone has had their MPG readout say anything like 0.4? I drove 2400 miles, and whenever I checked, it said that. It's really closer to 22 by my rough estimations. Before then, it used to be 17 MPG due to city driving.

 

Yep. Mine went to .2 and now its up to 2.8. Got about 8k miles on it now. Luckily the mpg isnt actually that low.

 

have you tried resetting the gauge to see what you get?

 

wheres the guys with the prochargers? wonder what they are getting

 

just reset the ecu.. same happened to mine..all is fine now..must be a bug in the calculation program

 

bump - I'm curious about that too...

 

The MPG calculator can only hold a certain number of miles before it rolls over. It's right around 7500 or so. When you cross that threshold, it will still think you used 350 gallons or so, but now you've gone 0 miles. Your MPG will go to crap.

To fix the problem, you don't need to reset the ECU.

Just reset the MPG calculator. To do that you just hold the bottom button until the MPG indicator shows the --- . It will start calculating again from that point.

-D'oh!

 

Thanks Homer!
