I have sat on this info since 2009 when me and another dude figured out how to jail-break the V-Max ECU for the first time, EVER!. Here are the pin-outs for reflashing the ECU. All that is needed is a FTDI USB to 232 serial converter cable, 26 pos Super Seal connector w/pins and a 12V wall-wart supply. Pin crimper would be nice as well. Note: I am going to show you how to reflash your ECU in time, but I am not going to give away my tunes. They are a product of a huge expense and years of hard work. Also, doing a reflash/tune, especially with a servo controlled throttle, requires someone very technically savvy. It is not for the faint of heart, so I'm still offering my tunes for those who would prefer me doing it for them. That being said, I am looking to find a way to encrypt my tunes and make it where you can fine tune it with my new flash package.
