Being relatively new to my Spyder bought new last summer, I thought it odd that I need to press the Eco Mode button to start the bike, but I've gotten used to it. For the most part I leave it in Eco Mode and I like seeing the arrow indicating when to upshift for best mpg, even if I ignore it much of the time. But I wonder how much difference it really makes to ride in Eco Mode versus not using this feature. I also own a Mini Cooper S which has a "Green mode" button, which wants you to upshift noticeably sooner than in regular mode, but the actual mpg doesn't seem to change at all, so I wondered if the same was true for the Spyder.
