"\nSport Chrono SC Package for MY2012-2016 911 BOXSTER CAYMAN 981 991 cayman s sport Chrono package with activation code.\n\n \nSport Chrono SC Package for MY2012-2016 911 BOXSTER CAYMAN 981 991\nLike PASM ( Active Suspension Management), the truth about the Sport Chrono Package has eluded many automotive journalists, many of whom have suggested that this feature is nothing more than an expensive stopwatch. Sport Chrono is much, much more than a watch.\n \nTRUE, THE SPORT CHRONO PACKAGE DOES INCLUDE AN ANALOG STOPWATCH MOUNTED IN THE CENTER OF THE DASHTOP.  THAT STOPWATCH CAN BE USED TO TIME ANYTHING, INCLUDING LAP TIMES.  A DIGITAL READOUT OF THE CLOCK’S RESULTS CAN BE READ IN THE INSTRUMENT CLUSTER, WHICH IS MUCH EASIER TO READ AND PROVIDES RESOLUTION DOWN TO 1/100TH OF A SECOND.  THIS STOPWATCH IS ONE OF THE BENEFITS OF THE SPORT CHRONO PACKAGE, BUT IT’S PROBABLY THE LEAST SIGNIFICANT BENEFIT. LIKE PASM, SPORT CHRONO PROVIDES A SPORT BUTTON THAT LETS YOU HAVE YOUR CAKE AND EAT IT TOO.  WITH THE SPORT CHRONO SPORT MODE OFF, A CAYMAN IS CALM AND GENTLE, EASY TO DRIVE, AND FORGIVING.\n\n\n\nSport Chrono Package Content for 991 981\n\n\nSport Plus key button\nSport Chrono Activation Module\nSport Chrono SC Module Connector and wiring\nSport Chrono SC Activation Code\nInstallation Manual\n\nNote:  the activation process must use the PIWIS2 or PIWIS3 system with the engineering mode to activate for car owners, in case you don’t have that please turn to your local technicians with system support. Turn the Sport Mode on and many characteristics of the car take on an aggressive and sporty feel. Among the changes are (depending on equipment):\n\nImproved Throttle Response\nIncreased PSM Intervention Limits\nThe Soft Rev Limiter is replaced with a Hard Rev Limiter proving full power to redline\nPASM changes to its Sport Mode (if equipped)\nTiptronic S or PDK switch to sporty shifting maps (if equipped)\nSport Exhaust is changed to its Sport Mode (if equipped)\nLaunch Control (on PDK-equipped cars, 2009 – up)\n\nMore detailed information background about the Sport Chrono SC package Understanding Rev Limiters A Rev Limiter is a safety device that cuts fuel, ignition, or both at a specified RPM to prevent an engine from continuing to rev beyond safe mechanical limits. Because hitting a hard rev limiter can be uncomfortable for the driver and hard on the car, Caymans come with a ‘Soft Rev Limiter’. A Soft Rev Limiter reduces power output by adjusting ignition timing as the engine approaches the cut-off RPM. As the ignition timing is retarded and power drops off, the resulting feel of power loss signals the driver that it’s time to shift. If a driver ignores this, ignition timing is retarded further until the rev limit is reached, at which point the resulting cut-off is much ‘softer’ because the engine is not being cycled on and off between full power and no power. A Hard Rev Limiter does nothing until the engine reaches the predefined engine speed, at which point fuel and ignition are shut off. This can be very abrupt and hard on the power train as the engine cycles on and off, but this type of rev limiter will provide the most power and acceleration, all the way to redline. This is how the rev limiter behaves when SC Sport mode is selected. Sport Chrono Plus Package Caymans equipped with the optional Communication Management (PCM) can be equipped with the “Sport Chrono Plus Package”. This is the same as the Sport Chrono package shown above plus extra electronic integration with the PCM display. That integration allows users to record, store and review lap times for each individual driver. Sport Plus Mode Not to be confused with the Sport Chrono Plus Package, Sport Plus mode is an extra Sport Chrono mode available only on Caymans that are equipped with Sport Chrono and PDK.  When Sport Plus mode is selected, the PDK transmission will deliver the following enhancements:\n\n1st Gear is always used from a stop\n7th Gear will NOT be selected at any time\nUpshifts are not delivered until 7,300 RPM\nDownshifts are delivered at 4,500 RPM\n\nThis shift strategy provides lightning-fast full-performance shifting that would be impossible to duplicate with any other technology.  This is ideal for performance or track driving.  Set the Sport Plus Mode, forget about shifting, and focus on your turn-in and braking points.\nDrawbacksUsing the Sport Chrono sport mode increases your chances of hitting the rev limiter as the hard rev limiter gives no warning that you are reaching the top of the rev range.\nDetails\n "
