Do a search on TuneECU, there is a ton of info about it, but in a nutshell - it is a software programme available for either PC or 'Droid. Pc is free, Droid is a small charge - but well worth it. A cable to connect to your bike will set yuo ha back about $20. Once you have those things you plug it all into the OBDII connector which is next to the battery. From there you can read the tune that is in your bike, load a new tune into your bike, and do a whole bunch of diagnostics and service work. It would be the best tool you can get for your bike.
