is there an external mpg reader that will plug into the diagnostic port? would like to be able to monitor mileage while driving not after filling the tank.
It is actually surprisingly accurate even with different sized tires and an uncorrected odo/speedo mine is almost spot on. There is also now another box just like the scan gauge but costs about 1/4 the price, can't remember the name now but I will look.

If this is the case, then wouldn't it be off by the same % your odometer is off (if you corrected the tire size)?
In other words, if your odometer is off by 5%, then so is your MPG.
