U will not need a PC if u get a reflash btw
Did you by any chance check other forum yet, as mentioned above?Don't have an FZ just yet, but if it was available for my R1, I would try it. I want to buy an Auto Tune to get a decent map for my area, the elevation(5200') sucks here.
When I get the FZ, I think this setup from Flash Tune will be the way I go, and I won't even bother with a piggy back(PCV) unit.
