I finally got a chance to try out the programmer tool on my 450. To start with the instructions are crap. They don't even show the correct leads for the 2011, only the older ones. I could get the program to load on my windows 7 machine, but not the driver. I had an old lap top that had XP and it worked fine with that. There is a new lead that has two plugs on it and both will hook into the bike's harness. The one that works is the one on the side of the lead, not the one on the end. I had it plugged first and it wouldn't recognize my bike. When you hook up the battery, you can hear the fuel pump start. I kept thinking what am I burning up with this thing. Once you get everything figured out it is not hard to use and you could change a map in 5 or 10 minutes. I loaded the soft track map to start with and will try it out this weekend. It advanced the timing and leaned out the fuel a little. Just starting it in the shop, it sure sounded crisp! I'll report back after I ride it.
