i jus bought my r33 gts-t skyyline n im still tryin to figure wat everyfin is, so i was wonderin wat the button that says snow or power not quite sure wot it is

it changes the rpm at which your auto box changes, so snow means soft low rpm changes, power holds the gear in longer

"Snow" mode launches the car in 2nd gear, to pull tractive effort out of the driveline and avoid wheelspin. It also changes the gears a little slower and at lower points to avoid (relatively) big changes of tractive effort. Pretty much useless in Australia, where you're unlikely to ever be in an environment with so little grip for the standard shift mappings to be undrivable.

Power mode holds the gear for longer when you're throttling. I believe it may also downchange faster under brakes. It keeps you in the meat of the power curve. You'd be better off just using the shifter manually, since its still not smart enough to do what you want when you want it.
