Basically you are correct. They now will be offer software that lets you monitor and log what is going on. They will provide a tune flash file that you can initiate at will. "I'm guessing" this software will back up your original settings before flashing new (per the change back at the track statement), and you can return to original if you desire. Some parameters of the tune will be adjustable by the user. I'll update the list with you .. follow those links earlier in the thread to the MB forum for more details.
