I think Sport crono+ is a waste of money because its launch control can only be used six times before it voids your warranty.
I think there is more to the
Sport Chrono Plus option than you think. Yes with SC+ on a PDK, you get the [Sport Plus] button to do launch control. However, on all cars, pdk and manual, Sport Chrono Plus buys you other things, beyond just the cool chronometer on the dash.
According to the Porsche configurator, it buys you the ability to select a more responsive throttle mapping, you get customization of things like lighting,... here is what the Porsche website has to say on the subject (of course substitute in PDK for where it says Tiptronic, as the websites don't yet contain the data on the facelift models:

All 911 models can also be fitted with the optional Sport Chrono Package Plus. it offers even sportier tuning of the engine and chasis, and delivers greater driving pleasure as a result.
Included in the package are ta digital and analog timer, a [SPORT] select button, a performance display and a personal memory function in the new PCM. Also - when fitted with PDK - a [Sport Plus] button.
When the [Sport] button is selected, the EMS SDI 3.1 engine management system enhances the engine response. A modified throttle map relates the pedal angle in the footwell to a much wider angle of opening on the throttle valve. Throttle response is significantly more immediate, and in the higher gears, a hard rev-limiter helps protect the engine under acceleration.
The optional PASM is also switched to 'Sport' mode for harder damping and more direct steering and therefore better road holding.
A hard rev-limiter is also applied in the PDK when gearshift points are delayed until the upper rev range. The shift times are shorter, the gear changes sportier. At low rates of deceleration - even with high engine speeds - the system initiates a swifter brake-induced downshift. In manual mode, gear changes are faster and more dynamic.
In 'Sport' mode, the trigger threshold for PSM (stability management) is raised for increased longitudinal and lateral dynamics. Agility is enhanced under braking for corners with PSM enabling greater maneuverability under braking and exit acceleration, especially at low speeds.
Supposedly there are other features such as the ability to program lighting, locking and other settings that you get with this option.
