Struggling with PDK
Discussion

Not really.
As I have explained in previous posts you can select your chosen gear, only for the car to decide you didn’t really want that gear after all.
For example I want a swift but not aggressive overtake so I push the selector into manual mode and drop from 7th to 4th gear, mirror, signal, manoeuvre – the car now drops to 2nd gear because I’ve applied more than 2/3rd throttle.
Another scenario, I’m approaching a curve at 50mph, traction is limited so with the selector in manual mode I downshift to 3rd and not 2nd in order to aid traction. As the car is exiting the corner and I straighten up the steering wheel I gradually apply the throttle – the car now drops into 2nd, the tyres become overwhelmed and the car goes into an unwanted oversteer skid.
I’m pretty sure that if you drove a manual car the way PDK drives then you would fail your driving test (if not definitely your advanced), which ultimately is my point of the thread and why I originally asked for help and advice.
I think there is something wrong with your gearbox, my PDK has never done either of the above two scenarios.As I have explained in previous posts you can select your chosen gear, only for the car to decide you didn’t really want that gear after all.

With PDK can I shift down 2 gears at once - either in auto or manual?
Not two gears in one go (in manual mode) but if you hold the downshift paddle (rather than just a pull and release) it will downshift sequentially until either you let go of the paddle or hit the limiter. However, I find that it's better to click the downshift paddle the same number of times to the number of gears I want to drop as it's more intuitive than the paddle hold method.Try the dynamic downshift; at the point where you think you need to shift; tap your foot on the accelerator - the systems see the speed of throttle application and select a lower gear. Best tested in the seat rather than explained in a sentence......as the effect can vary depending on how far and how fast the pedal is pressed; described as a 'stab' is probably most fitting.
OP is not using the box correctly.
MANUAL MODE: select D then move lever across to M, the box will select the lowest gear for pulling away and will allow the driver to decide when to change gear within the parameters 'from idle>redline'.
In Manual; if you shift to 6th (if the road speed allows - as the parameters still apply) you can lug the car around very inefficiently to your hearts content; similarly you can hold 2nd til your ears bleed if you like.
MANUAL OVERRIDE MODE: When in D, initiate a gear change with the paddle and you have a predetermined time to select another gear before D is resumed - watch the gear display; press paddle; M and selected gear light up; continue driving without further intervention and the original program resumes - you have left MANUAL OVERRIDE MODE
Depending on SPORT / SPORT PLUS (if spec'd) or PSM Off selection the systems can allow you to get close to or sit on the limiter if you wish.
On cars with COAST mode; lifting off the throttle gently at speed will open the clutch and the car will coast along on idle - by either braking, accelerating or pressing a gear paddle the clutch is re-engaged again giving another facet to the system.

I read somewhere on PH - so it must be true - some guy mentioned he was at a Porsche track event playing in modern Caysters and he asked one of the Porsche instructor types about using the manual mode and he said its better to just leave it in auto because the car is clever-er-er than the human driving.
The car is not smarter than the human driving, it doesn’t have eyes and it doesn’t know your intentions for a start. However on track you want to be in the lowest gear possible for the road speed and you want the changes to be as late as possible, therefore it’s much easier and quicker to just leave it in Sports Plus.Pope said:

Thanks Pope, however it’s not a case of me using the box incorrectly. I’m aware of the manual mode and the manual override mode, and I’m aware of the ‘stab’ as you describe it.OP is not using the box correctly.

It’s a case of “I know how to use it, these are the faults, does anyone know of any solutions?”
Ultimately many of you think it’s acceptable to instruct the car to change gear even though it has a manual gearbox, I do not.
Naïve? Maybe. I will sell the car and buy something with a manual gearbox, but at least I gave a PlayStation style car a try with my own money and didn't just drive it for 30 minutes and then slag it off on the internet.
Hope you all have a happy new year

I have read some pretentious drivel in my time but this thread is the 2016 winner for sure.
Anyway, off to pull some skids and train the Porsche test drivers whilst flapping my paddles...

And here we are again.
What many are confusing here is a manual gearbox with what Porsche call 'Manual Mode' in a PDK automatic box.
They are entirely different things and to equate the two different uses of the word is to have a limited knowledge of gearboxes.
I don't think people are confusing the two technologies. Ultimately they do the same thing, ie change gear ratios. An auto doesn't let the driver choose the gear, but a manual or manual mode does. Who cares what makes it change gear as long as the driver can choose. What many are confusing here is a manual gearbox with what Porsche call 'Manual Mode' in a PDK automatic box.

Both have pros and cons but both only change the drive ratio

PDK is the perfect gearbox for you. You can ignore this thread.Who cares what makes it change gear as long as the driver can choose.
Are uou going to tell me that its not the role of a gearbox to enable the driver to change gear ratios?

I only offer my own view that its not for me, I much prefer a full manual gearbox with all of the interaction and control that brings. Its WAY more than just changing ratios.
You say you dont care and thats totally fine! PDK it is for you!

What balanced view do I need? They are very different gearboxes with different pros and cons that attract different people. For what its worth, I reckon the PDK is a fantastic bit of kit and certainly the best auto I have used (in any mode).

That's great and totally understandable, no one (well not many people) are saying everyone should like the PDK better, and most recognise the strengths and weaknesses of each and choose accordingly, all good.

However.... the reason this thread is going on and on is the OP seems to have some off-the-wall reasons for rejecting the PDK that do not square with anyone elses experience and lead you to believe that either, the OPs PDK is not working correctly, or the OP is simply trolling.

You must be trolling, as you're deliberately ignoring numerous people confirming how the gearbox works (conflicting with your claims), and instead seemingly trying to pretend the fact you seem incapable of using the PDK gearbox somehow makes you superior!It’s a case of “I know how to use it, these are the faults, does anyone know of any solutions?”

As I suggested earlier, it seems more likely that it's the driver at fault rather than the gearbox.Hope you all have a happy new year
Still, good luck with your Porsche factory drive next year - I hope you can still 'pull some skids' when you win a race...

I can make my car coast by changing up if the throttle lift didn't. Gassing Station | Porsche General | Top of Page | What's New | My Stuff
