From a local dealers site.... Didn't "snopes" it, so take it for what it's worth...
"There are some very exciting upgrades for the 2014 Summit X 800 E-TEC besides BNGs. that starts with new handwarmers with 50% more heat at idle and a little more heat if you want it while riding. The gauge now notifies you when you over-rev so you can mess with the sleds brain when you adjust you quick clickers too far.
We've all had that ahh-hah moment when the ECM allows full performance setting after the break-in period. Now then gauge will countdown and display what percentage of break-in period is left. The sled will also beep at you now if you leave the parking brake on."
