All ive played with in mine is lock which seems like a good way of stressing you driveline out if u use it on the roads for launch or drift... All the way down to the bottom green which I like most for motorkhana powerslides and by far the most usrd for me being auto... The computers are most of the time spot on the money so I dont stuff with it much even after 2 years.
But thats just my personal experiences and opinion.
