I'm about to order a Cayman S and had a question regarding Sports Chrono. Is there any performance difference between Sports Chrono and Sports Chrono Plus? I'd rather not have to upgrade to the PCM but will if there is anything performance oriented I would be missing by getting the SC vs. the SC+
If all it does is add some data acquisition and timing functions I'd rather save the
$3100 and spend it on after market components.

Thanks

The difference between SC and SC+ is that you get a 'personal memory function' and a 'performance display' in PCM. In cars with PDK, SC+ also gives you an even more aggressive throttle map than SC, locks out 7th gear (so the computer will never shift into 7th), and provides the Launch Control function.

I am pretty sure that all of the performance functions of SC and SC+ are the same (eg. launch control and throttle map). My dealer and Porsche literature seem to back that up. It is only the memory and programming functions that are added with the PCM (and satnav with the ability to get sattelite radio).

Well that doesn't seem worth $3100 to me.

I don't think that's right.

I've read literature that states that in PDK cars, SC+ provides an even more aggressive throttle response than SC - in fact, in SC+ upshifts will only occur at redline, which is quite different from SC. Also, the Porsche website specifically states that SC+ is required for launch control (in fact, you have to press the 'Sport Plus' button to activate LC - 'Sport' won't do it). One more thing that I've read is that in SC+, PDK gearshifts are even faster than in SC or normal mode - my paltry experience with SC+ backs this up.

Additionally, I've tried SC+ and 7th gear IS locked out - in automatic mode the computer simply will not shift into 7th.

I'd say these are additional performance differences that SC+ has over SC, with respect to PDK.

I called my dealer to check and he told me that the SC also has launch control. The Porsche wesite is very vague (maybe intentially to sell PCM). It would be nice if Porsche actually described this in detail accurately in Their literature.

Sorry, your dealer is wrong. Launch control is activated ONLY with the Sport Plus button, not the Sport button. It's even described on the Porsche website ("Launch Control is operated via the Sport Plus button" - hardly vague). From automotive.com's site:

In Sport mode, the transmission shifts more quickly, with more positive clutch engagement. Sport Plus adds much quicker shifts at full throttle, and both modes use a more aggressive shift map in automatic mode. The Sport Chrono pack also includes a launch-control feature for the PDK, which dumps the clutch at 6500 rpm and then modulates throttle if necessary for optimal grip. It also knocks an additional 0.2 second off the rush to 60 mph (now accomplished in only 4.1 seconds for Carrera S models, 4.3 seconds for the base model).
Although this review is for the 911, SC+ operates virtually identically on the 987.

Trust me, Launch Control doesn't work with just the Sport button. I've tried on my own car. You should tell your dealer to get his facts straight - all he needs to do is take a look at a 2009+ Cayman owner's manual.

Sport Chrono + on a 6 speed manual car gives you the lap memory functions of the PCM. With the PDK, SC+ adds the PCM functionality, launch control, and much more aggressive (shorter) shift duration times than even regular SC. It also locks-out 7th gear, and gives you shift points in auto mode at redline. You have to have SC+ for PDK launch control. SC+ does not change the aggressive throttle mapping that already comes with regular SC - that stays the same as regular SC, which is more aggressive than without Sport Chrono.

Unfortunately, dealer personnel get this stuff wrong all the time...

Holy Cow!...if this is right Porsche really went on a money grab here.

So to get launch control you have to have SC+ and hence PCM? So a PDK with everything necessary to extract any virtues from it lists for $7850 USD?

Do I have it correct?,.....dang, that's PCCB in a heartbeat!

Yes, I believe you are correct.

Thankfully the price difference between SC and SC+ is negligible. As far as requiring PCM....yes, that's a bit of a grab.

Agreed, that's a big grab... but for a PDK-equipped car - at least imo - SC+ is a requirement - particularly for the WAY faster shifts and the way it shifts in auto - where PCCB wouldn't be. The steel brakes are pretty good as they are.

I personally couldn't justify $3K for SC so I decided against it.

The good news is I opted for "Sport Mode" with the Softronic tune plus it came with additial hp & Nm/ diag cable for less than half the price of SC

I have a 2009 CS with 6sp and Sport Chrono--no plus, no PCM. Let me tell you, as a timing device, without PCM the Sport Chrono is worthless. There is no memory without PCM, so when you leave the track you cannot scroll back through you lap times. Also, the cute tracking system where the PCM graphically displays your current lap against a previous lap is also missing without the PCM.

Now, I like sport mode for the revised throttle map and revised stability adjustment--but as a timing device, it is worthless, and there are some great data acq devices for much less than SC with PCM, and they supply much more data.

The revised throttle map of sport mode makes heel-and-toe downshifts much easier for me. Not a consideration for PDK cars.

Carry on....

True about SC+ with PDK, I couldn't see owning it any other way.

As far as PCCB goes, at least it is less unsprung weight and does perform better at the track,....something I have yet to see PDK do in a verified run.

And for some, if exchanging this amount of $$$ for PCCB is not a good choice, next on my list would be the soon to be announced DFI version of the TCP Racing ATP:L turbo for $7490. At least with it you will get a guaranteed performance increase.

I have discussed this point with the dealer, and checked out the cars in the showroom. We have all been confusing Sport Chrono+ and Sport+. If you buy Sport Chrono and PCM, you get the Sport Chrono+ version, which enables some time recording on the PCM computer. You will have the Sport and the Sport+ commands for the PDK (if you bought that also). BUT if you do not buy PCM, and only Sport Chrono, you will still have the Sport and the Sport+ settings for your PDK. I too was unhappy at the prospect of having to buy an expensive device, PCM, that has little functionality for me, in order to get the most out of PDK. The question for me would be, do I really want a $3000 GPS unit?

Hm...you may be right. I just did some digging on Porsche's website and found this:

In combination with Porsche Doppelkupplung (PDK), the Sport Chrono Package offers two additional functions that are activated by the Sport Plus button.

First, ‘Launch Control’, which ensures you achieve the fastest possible rate of acceleration from a standing start – on the racetrack, for example. ‘Launch Control’ is operated via the Sport Plus button with the ‘D’ or ‘M’ drive position selected. Whilst the driver depresses the brake pedal with the left foot, the right foot depresses the accelerator pedal to the floor. With the accelerator in the kickdown position, the system detects the driver's request for Launch Mode and revs the engine to an optimum speed of approximately 6,500 rpm. Engine torque increases and the clutch closes slightly. The message ‘Launch Control active’ appears on the instrument cluster display. The driver now quickly releases the brake – and prepares for maximum acceleration.

Second, the ‘motorsport-derived gearshift strategy’. Using this, PDK is geared up for maximum shift speed, the shortest possible shift times and optimum shift points for maximum acceleration – for uncompromising performance.
With regards to SC+, the same page says:

On request, the optional Porsche Communication Management (PCM) can be combined with the Sport Chrono Package Plus. In addition to the functions of the Sport Chrono Package, it includes a personal memory function, which can be controlled using the PCM, and a performance display for evaluating lap times.
So I guess what we can conclude from this is: Sport Chrono alone features launch control on PDK cars, and PCM is NOT required. bearman, I stand corrected, and owe you an apology.

Interpol, No apology necessary. I had just complained to my dealer about not getting correct information after reading the previous replies but was mostly bummed out about not having the performance features coming on my new car. Now I am happy again and look forward to the highest level of performance available from the factory. :)

Hi all,
Thanks for the replies. This board rocks and is Way more active than the audi board. I look forward to being here more once my Cayman S arrives this spring :)

So this means that when ordering SportChrono you get Sport AND Sport+ buttons, and SC+ only gives the additional PCM funcs??
