I've read about the advantages and applications of Sports Chrono on a PDK. But what does it do for a manual transmission? Thanks in advance.

It shifts a bit more responsive...

Better suited for PDK...IMHO

Same as the PDK but minus the launch control and speedy auto shifts.

So with sport button on;
- quicker throttle response
- hard RPM limiter vs. soft then hard (as revs approach redline, soft limiter pulls timing first)
- larger limits allowed before PSM steps in
- switches PASM to firm without having to hit both buttons

The obvious gauge and timing feature (good for timing how long it takes the gf to come out, or how long a stop light takes to change, etc.), incl. the recorder (but honestly, does anyone actually use this?)

The ability to change things like how long the lights stay on after the car is shut off, wiper settings, DRL, etc.)

I'd say essential for PDK but only nice to have for a MT.

so true...

Answers will vary. I think you'll find hard-core track guys like me don't care for the Sport Chrono. Doesn't really do anything useful. The change in throttle response is basically a trick and all you have to do is press the pedal 1mm more to get the same amount of throttle. I keep reading this thing about soft vs. hard redline and it just doesn't pan out. My car pulls 100% to the redline, which isn't where you ever want to shift anyway because you are already past peak. The change in PSM is also irrelevant in the Gen 3 PSM we now have in the 09+. If PSM kicks in then you are doing something terribly wrong. As I undersand SC, if you turn PSM off (why?) then it won't kick back on unless 2 wheels are in ABS vs. 1 on non-SC (or something like that).
