Pony, please keep us posted. I too have had an interest in data logging/remapping my '08 Scg but have had no real definitive answer after reading nearly 100's of threads, of which almost all dealt with pre '08 bikes. Btw, TunerPro RT is a free, (read: donation optional) program.
From their website:
"Both TunerPro and TunerPro RT are free. TunerPro RT has a "nag" window at startup for unregistered users, but the software is feature-complete even without registration and the software never expires (many shareware packages do). A $30 "donation" will allow you register TunerPro RT, removing the nag window. Registration is not required."
