Maybe the cc issue needs its own thread,... but what the hell.
It helps me in the work truck, usually by a couple of mpgs but I don't let do all it likes. As I start up the numerous hills along my drive I'll hit the decel button as I feel the truck losing momentum. If i get it right the truck will slow somewhat, and not downshift it stays in the OD gear and lugs abit. After cresting I can use the accel button to regain my speed in the OD gear. The key is to make the computer not downshift, and you have to hit the button slow to do that.
