You've never pressed the SPORT button in your C2S? Interesting. I find it a huge deal.

If there was an option from Porsche Factory called "Sport/non-Chrono would you order it?
I think folks are too focused on the $30 dash wart when they speak about the Sport Chrono. It's 10% timer, 90% other features. The chronograph on the dashboard is truly incidental in the option. This includes 6MT and PDK.

Here's a link to a porsche microsite with Sport Chrono info for all Porsche Vehicles:
http://www.porsche.com/microsite/tec...lectedVariant=
For the 911 Carrera MT I see the most relevant benefit to be enhanced throttle response described as "significantly more immediate" and PASM automatically goes to sport mode. It can also be used to program some personal settings for lights, wipers, door locks, air conditioning....
For the 911 GT3 it adds nothing of relevance from my perspective. NO effect on throttle; only on personal settings as above.
this is per my reading of the microsite and not personal familiarity with the SC in these vehicles. The site goes on about SC in PDK and Turbo cars....

Lot's of ignorance on the Sport Chrono matter in this forum, guys. If you aren't sure, don't speak 
It is highly recommended on both PDK and 6MT! (not only for resale) And it should be called "Sport/Chrono", not "Sport Chrono".
Here is why:
Even if you have a 6MT it adds an enhanced throttle mapping program to your car when you press the "sport" button. Essentially this gives you a sportier response to the ratio of your accelerator depression. (although it does not boost hp).
It also feathers the PSM (not PASM!) and gives you more control over your car while not completely turning off the the PSM assistance. PSM is the Porsche Stability Management system (wheels that slip to the wheels that grip, system) This is a half-mode that would not be available if you hadn't ordered the Sport Chrono option. (yes, even on 6MT cars)
It also hunkers down the PASM suspension (which can be overridden and turned back off if you prefer to keep your teeth in place.) And gives you a one-button activation for Sport Exhaust, PASM and PSM. (on both PDK and 6MT)
It also gives your car some memory slots for things such as power seats and lighting. Not a big deal.
(It gives launch control for PDK)
And yes, you also get the cheesy egg timer dash wart which some people like.
THIS ALL BEING SAID, there is now a PORSCHE FACTORY kit which you can order after the fact. It gives you the ECU (computer) software program and a sport button as if you car was ordered with Sport Chrono. Although you will not get the egg timer on your dash. There is an actual Porsche part number for this upgrade - many service depts won't know about it. It's about $870. MAKE THEM GET YOU THE PART NUMBER! Teach them
Suncoast can also sell you this kit. Your pick...

It's absolutely essential.... It has a neat bump on the dashboard if ordered from the factory and two more switches next to the PCM.... I love pushing and pulling buttons and switches so even if it didn't do anything it would still be worth the money...

I rarely use it except when in the mood to drive aggressively, which isn't such a good idea on most occasions around town. I don't think it makes the car faster, but certainly more responsive - some might say jumpy. I prefer the smooth and linear delivery of the normal throttle mapping, and with a Cab I think it's less important, as the intended use of the car is usually somewhat different than a coupe. Does seem important for resale - if not in value then in desirability.
I would agree, IMO.....the PDK is no fun without Sport Chrono or Sport Mode.

I press sport as soon as I turn the car on and then press PASM to normal. I have SPASM so i like riding in normal PASM for the most part. With a PDK car you have to have SC. With a 6MT, I'd still get it. I personally like the wart. It breaks up the dash and it's not unattractive.

Silly Stop Watch ? it allows me to calibrate my speedo every time I get behind the wheel. NO 'normal' driving tickets is the goal; 48 sec. = 75 mph. The Sports Chrono is more then just the bump on the dash and it's very helpful to the 4s w/ pdk. Clarkson of TopGear refers to it as a 'wart'. I disagree yet enjoy his constant re-testing of the 911.

re: Opinions on sport/chrono
My came with. I don't track my car, although launch control every once in a while is fun.
I do use the Sport/Chrono to keep tabs on how long it takes me to get home from the airport. I usually fly in late at night, so I make the drive home a timed event. Helps pass the time.
And yes, I park the '09 C4S Cab PDK in a private level with security at the airport!
Best,

My post from another thread about the same thing
"WOW
Some of the posts just don’t make sense and are of no help.
I have a 2005 C2S with Sport Chrono. Without any push of the button the throttle response seems fine. It is not overly touchy but isn’t dull. The suspension is very complacent and deals with bumps quite well (for a sport car). Once you hit the button both the throttle response and the suspension is changed. I wouldn’t say either are a wild difference but it is easily noticeable by anyone and everyone. The throttle is more precise and reacts much faster to any input. It borders twitchy but hangs in there to make it a nice adjustment. The suspension gets harsh, but that is exactly what it is supposed to do. I NEVER have the suspension portion turned on unless I am on a 100% smooth road or on the highway. In these two setting the car feel more balanced. Any steering inputs are more precise and the overall feel for the road is increased.
Example: I was on the highway when I first got the car for a 5 hour trek from MA to NJ. On a part of the highway the road was smooth but it went up and down in a very shallow wave pattern diagonally across the surface. The car began to sway back and forth as I went from high point to low point and back again. Almost felt like I was on a boat so I hit the little button and voila…smooth sailing!
I cannot speak to the technical changes but do recall that it also changes when the cars electronic stability and other safety things kick in, higher with it pushed, lower without.
Is it a MUST HAVE…no. For the extra cost is it smart to get…yes. Will you use it every day…maybe the throttle but typically not the suspension. If I were to spec out a new 911 would I get it…in a heart beat.
I hope this helps clear some things up. I would be happy to expand on any of it if something is still unclear."
