Hello... I'm trying to come to grips with the information I'm finding on the Speed Passion website and what I can get from reading back through posts on this thread. Help me understand... if I purchase the "GT2.0 LPF Brushless ESC", it looks like (from the pictures, not necessarily the description) it comes with some sort of digital device... is this what I need to do the programming, or do I need the "LCD Professional Program Card"? Or both??

Or is it a case where you can do a limited amount of programming/setup with the device that comes with the ESC, but to do the really fancy stuff, you need the Professional Program Card and software you install on your laptop?

I'm struggling to keep up with the technology here. All I know is, I'm still running an old Novak GTB and in the past few weeks my competitors, who used to run at roughly the same speed as me in 17.5 sedan... most of them have purchased the Tekin RS, and they're figuring out "timing advance" profiles and are suddenly a lap faster!
