Sport and be specified on its own but Sport Plus needs Sports Chrono and that is needed for launch control. For PDK then I would certainly recommend Sport as that delivers keeping the gear down one. Yes its all money but I wanted Sports plus and launch control, its all personal choice. I had 18's without PASM before and went for 19's this time as I like the wheels. I had long discussions with OPC about the ride and eventually did not spec PASM. I have Pirelli's and the ride is quite a bit harder than the original Cayman S on 18's. I ordered back in December so did not have the opportunity to test drive Gen 2 with and without PASM, I accept I took it on faith. I also added LSD
I assume you mean Sport button is standard with PDK, if you speficy PASM this also switches to hard. One of the reasons for changing is I find the GEN 2 suspension very hard and PASM on 18ins should be a lot more comfortable. Do you find Sports Chrono useful or just to show off launch? I cannot justify LSD as its only really tight bends causes the inside wheel to spin.
PDK sounds technically brilliant. But, I wonder. Don't you miss the fact that you can make duff changes, or be in the wrong gear ? By which I mean, because you can get it wrong, it feels even better when you get it right ? Lets face it, you could make a car so technically advanced, it could drive itself round a track much faster than any of us could, but that would be boring. I'm sure PDK users will defend it to the hilt, just wondered if any feel that something is lost at all ?
Soon as you take in out of "auto" it's very easy to be in the wrong gear! No duff changes though. So unless the choice is to troll around in auto all the time you still have to be very much aware of the revs/gears etc. In fact blipping down a couple of cogs as you brake hard approaching a bend is quite satisfying. Of course if you forget you are in manual when you come to a halt it will obligingly select 1st. I rarely use it it auto on the open road although it does have a few protections built in - such as if you're overtaking, in manual, and on the kick down button, it will change up at the red line if you forget to - although if at full throttle but not on the kick down it will bounce off the rev limiter. (Yes, of course I have done that! Doh!) So, as I say, as long as you get it out of auto you're still very much in charge (without the crunching) and it suits this old duffer very nicely!
I agree Sport Chrono and launch control is purely for fun, and is not used a lot, as you need a standing start and fairly straight road ahead but is fun when used. Sport Chrono for timimg laps is not a lot of use unless going in circles or round a track. This choice is the same for any Porsche and in some ways its a shame that it is the only way to get the launch control. In reply to Gary C with the kick down you can change one or two gears and in manual mode its controlled via the steering wheel buttons or the manual action using the gear stick of pushing forward to pulling back to change gear so there are still many ways to make it more exciting. I personally have found the steering wheel buttons far easier to use then the manual selection with the gear stick.
Martin, I was asking in another Boxster thread about PDK mpg as I got 23 after the Chobham track and 33 going back to the dealer on a mix of town and m'way. Whereas my GEN 2 S manual does 32 so far. What are your findings so far, if you dont monitor it what does the info mpg read to date? Chris
Chris, I had a look at the average mpg achieved over the first 2,000 miles with the PDK gear box and it shows 26.8 mpg average. It is fair to say that I have a very heavy right foot and accelerate whenever I get the opportunity. This includes playing with launch control which I expect is not fuel efficient. Personally I only do about 6,000 miles per annum in this car and the differnce over a year at 4 3mpg is only £100, so I prefer the excitement rather than maximising mpg. If I was worried about the fuel consumption I doubt I would buy a Porsche in the first place. Interested to hear what others have achieved over the life of their cars. Martin Martin

I got 26.03 mpg overall for the first 1600 miles. Given that this was in a 911 3.6 C2 Cab, bigger & heavier than a Cayman, I'm sure 30 mpg is quite possible. By the way, this was real mpg, calculated the old fashioned way, not by using the onboard computer which always produces a better figure.
Martin & Derak, Do either of you have any comments on today's post about PDK afer 2500 miles? I tend to agree with his 2 critisims: 1.When pottering in 7th it doesn't change down fast enough to overtake unless you use the paddle switches, I was told by my instructor to hit the gas pedal 2. When stopped in traffic it disengages the drive then when you touch the gas to move off nothing happens then there is too much delay before it clunks into drive. Chris
I believe the DSG, F1 or Sportshift boxes burn out there clutches very quickly if one leaves them in gear creeping mode like an auto box and presumably this would be the same case with the PDK clutches hence the dropping into neutral mode [&o] My brother has an AMV Sportshift and was told to keep his foot firmly on the brake pedal which was the equivalent to having ones clutch pedal fully depressed and if the stop was for a period of time slip car into neutral mode!
Point 1 - If you're pottering why overtake?![
] Seriously though it does adapt the gear changes up and down to the way you are driving (accel and brake) Point 2. It doesn't disengage the drive when stopped and there is no delay or "clunk" before it moves off - not on mine anyway - which is why the manual says " for a BRIEF (my capitals) stop (e.g at a traffic light) leave the selector in the drive position etc.. This is the first reference to anything like this that I've heard with the PDK and I'd be inclined to check it out with the PC.
I have not found the overtaking changedown to be an issue. I tend to use the accelerator and a button to get down fat. I also noticed the slight delay but don't think its 2 seconds. I mentioned this at Silverstone and was told it might be the timing, took mine back to OPC and they checked it out on the computers and said it was fine but to tell them if it continued, which it does, now armed with this other thread they will be seeing me very soon. Maybe leaving a few extra feet behind the car in front and preempting the movement of the cars or lights is the way forward. I also agree that it would not put me off PDK as you only start off accasionally. Martin
These issues need clearing up for me before I decide whether to go PDK as they are every day driving situations. I am planning on borrowing a PDK to try this out again next week and will report findings. Point 1 - by adjusting the kicking the throttle it changed down OK this seemed to OK except you are nor sure what gear you are in without looking down at the read out. By the way I thnk the gear read out is a real plus feature. Point 2 - there was definitely a lag between accelerater input and the car moving, then there is a slight clonk as thr drive decides to engage - this was when pulling in fornt of traffic at a roundabout when you need to get going quickly. Other questions for me are: Point 3: I am still not 100% clear about Sport mode, is it standard with PDK and if you select PASM option is it the same "shock absorber " logo'd button that gives you the PASM in the hard setting but with a different logo on it? Point 4: Is Sport Chrono worth the extra cost if you do not plan to use launch or track it? So the only features would be the quicker gear change up and down and 7200 hard change up limit, plus the stopwatch of course. ChrisORIGINAL: tscaptainPoint 1 - If you're pottering why overtake?![

Floor the throttle at 50 mph in 7 th gear and be prepared to be amazed. It is awesome. Not sure about your second point, mine seemed ok.

Don't get confused between Sport Chrono and PASM sport settings. Sport Chrono is not standard with PDK, nor is PASM (though PASM is standard on a C2S, not a C2). Sport Chrono is worth having with PDK as it allows you to completely remap the gearbox and engine. Launch control, IMHO, is a gimmic which Porsche feel they have to offer. Fun to do just once. PDK is essential in my opinion [

Re point 2 Chris I did a little test today on the car - see this thread http://www.porscheclubgbforum.com/tm.asp?m=461216&mpage=1&key=&#461216 Sure if you go from "N" to "D", "R" or "M" then there is a short time while the gear engages and the owner's manual tells you to wait until the gear has engaged before you use the accelerator. But if left in D or M mine does not go into "Neutral" by operating the hand or foot brake and no clonking! And there have been no possibly embarrassing pauses before moving off. I agree with Derek that "launch" is a party piece but needs to be done each time you take a new person out in the car for the first time![]

So assuming the Sport button is standard with PDK, if you opt for PASM then the Sport button gives you the PASM hard setting? If you go for Sports Chrono does it also give you the PASM hard setting when you can click either Sport or Sports Plus buttons?ORIGINAL: dereksharpukDon't get confused between Sport Chrono and PASM sport settings.
