I have an early Z1 with the original software and the Ducatiboy headlight flash bypass. I am in the process of reinstalling it in a different vehicle, good time for upgrades and/or fixes. My question is, if I install the bluetooth and "overheat" fix (I live in Phoenix so I need it), does it override the flasher bypass. If so, is it now as easy as using the grounding method I have read about to "unlock" the unit while driving? Also, anybody know what wire is the Speed sensor wire in a 2003 Avalanche? Thanks

Anybody? It's just a quick answer I'm lookin for. Found the speed sensor wire. Thanks

If you upgrade the firmware on your Z1, then the ducatiboy flasher will no longer work for the bypass. You will just need to do the simple 2 wire grounding bypass.
