Unlike RC, i'm keeping my 2011.. and will be flashing it via...you.
that said, I just got my ecu back from Nick. thanks to all the border BS, USPS 'misplacing' the ecu for over a week, it's finally back after a long 3 week hiatus.
The FZ is transformed, so I have no doubt your flash will do some small wonders for the ST.
That said, the FZ thorttle was god awful compared to the ST. It needed it in a bad way.
just to be on the safe side, and avoid any close calls/personal heart attacks, i'll be sending you my ecu in the dead of winter.
