Heard about that feature too but I have never heard if it was a done deal or not. I think any application would benefit from that feature even it was on a boat instead of a big rig tractor. Changing it on the fly or having it done automatically for best fuel savings would be a big boost. Gas prices just jumped upward 13 cents today in the Midwest.

These fleet owners could be saving millions on fuel and have the units as a tax write off to boot. What IS the delay???
