ECO PRO is a joke. I will not dispute that and don't bother with it anymore.
However, the BMW computer is equally as flawed. Not only is the speedometer a few MPH too high, but the MPG calculation is way low. My first tank of gas showed 21.7 MPG on the computer but my own calculation showed 24.2. My second tank showed 23.0 when my calculation showed 25.9. Do your own calculations.
