I noticed today that you can update the USB programmer as well as the speed controller...

Up until now I have used a Hobbywing USB programmer to put the new software onto my GT2.1 ProStock and then changed the settings with the Speed Passion programmer that came with the speedo.

Is this correct or should I be updating the Hobbywing programmer and then using that to do my programming - and why do I need to do that?

Hope that makes sense...
