Hey guys, I just installed the ABS dongle. Its main purpose is to allow you to save your ABS setting when you turn off the bike. Without the dongle, the ABS defaults to street mode.  The dongle also ads a completely disabled mode for the ABS, so you can lock up the front wheel, and allows you to use the "bad-fuel" map program.  The curious thing is the instructions say not to use the "bad-fuel" mapping for more than one tank of gas.
