I have come to have a fairly good understanding of the PDK and find myself getting a lot of joy out of it.

There was one question that I am almost sure I know the answer to but wanted to check.

If one is travelling at speed and downshifts for added acceleration. If one were to miscount the shifts. I am assuming that the PDK would not take you down to a gear that would be the equivalent money shift in a manual and so if the lowest safe gear at a set speed was say third gear and you pulled Left paddle one time to many it would not take you into second.

I have once or twice landed at a lower gear where Revs shot up but only too the Mid 5K range and scared the **** out of me but I am assuming if I was going to go above Rev limiter it would have prevented the shift

Thanks

Correct, no over-revs possible with PDK.

On a related note, if I am entering a turn at high speed and I downshift one (or even two) gears, while on the brakes with my right foot, will the system rev-match?
Obviously, I know it will go into the lower gear (assuming no over-reving).
But will it emulate a heal & toe action and blip the throttle to smooth the transition from acceleration to deceleration?

one way to find out!

You know it's funny.....it seems like it does.
But it's hard to differentiate between the possibility that it's just softening the clutch-pack engagement or actually blipping the throttle.
There are a lot of things like this that are hard to really exploit on a public road. Left-foot braking is part of this same question too (for me, at least).
I haven't taken the car to a race track to really try any of this....but that is what is really needed.

It rev-matches to perfection, both up and down shifts. It's all computer controlled.

My only complaint, sometimes both the AutoPDK and I downshift simultaneously, normally from 3d at a 90 degree corner and I get a 1st at about 6-6500 rpm, terrifying myself, women and children and the fauna all around.

To make things worse, since the wheel is turned more than the amount I can keep my hands at the '10 to 2' position, and I hand-over-hand the turn, I can't find the blipping paddle to upshift, while the engine protests in indignation about the treatment (oh yeah, you can hear the PSE on S....). Talk about embarassment...

Thanks. I've been wondering about the rev-matching.

And my point about the paddle shifters being attach to the column would solve this. But... easy fix if you use the gear selector to do the rowing.

yeah, I hear you... But for my subliminal setup, the upshift/downshift is wrong. You need to push forward to go faster and to pull backward for engine braking. I've thrown it wrong a couple of times in my wife's Bimmer, earning poisonous looks . At least the paddles, I learned it right from the beginning.

I'd love to have the 'paddles on the tree', but ...'that's not how they have them in Formula 1'..... Anyway, I am almost there, it's in city driving that I have to turn the wheel this much.

 

[HooosierDaddy]

The gear selection with the stick is intentionally done this way so you don’t upshift on a hard braking situation and as far as I know only on the 911 & boxster/cayman lines.

Agree that it seems counterintuitive, but on our macan it is the other way and sure as &@$* the one time I try showing off to my wife (still gotta impress the ladies you know) I flubbed it braking into a corner and she had plenty to laugh at. ?.... and they never let you forget!

Yeah, I've done that a few times. I finally gave up trying to second guess the PDK for most situations and started using manual mode when I want to shift for myself.

Of course, after 18 months I'm still not used to having no clutch pedal. And it took me a long time to learn the instinct of which paddle was which. (It's my first and only paddle car.) And I still can't get used to the fact that in some situations, such as at a stoplight, manual mode will downshift to 1st for me if I forget. And of course I run manual mode so infrequently that I always forget that I'm in manual mode until the sky-high revs after start-up remind me that I need to shift for myself. Just running in auto mode is so much easier!

The direction that the stick works in a 718 is the same as how a sequential shifter (race transmission) works. In cars that work the opposite way reviewers point out that the shifter is backward.

 

[aeronca65tl]

Interesting conversation.

I just see using the PDK floor shifter in manual mode as very different and sort of a unique thing to be learned. Like playing the oboe or something.

I own six classic Brit cars. Five of them are 4-speed and has an updated 5-speed.

On all of them the 1- 2 upshift is back.
The 2-3 upshift is forward.
The 3 - 4 upshift is back.
And in one of them the 4 - 5 upshift is forward.

So I don't see forward being only related to upshifting (or back being related to downshifting).
That's my story and I'm sticking to it

 

[Lelandjt]

You're talking about a H-pattern. The PDK's stick shifter is setup to mimic a sequential shifter, not a H-pattern. A sequential shifter is a race transmission that works like a motorcycle transmission and is what race cars used after H-patterns but before automated clutches. Sequential shifter are ALWAYS forward for downshifts, back for upshifts.

 

[DriveInHouston]

I see now the motorcycle heritage!

 

[aeronca65tl]

"You're talking about a H-pattern......."

Obviously.
And its relationship to what is often called muscle memory.
There is nothing that says a task like manual gear shifting can't be unlearned. But for some of us, the process I described above has been wired-in over many decades. My first autocross was in 1969 and my first wheel-to-wheel race was at Bridgehampton in 1973. I'll try to re-wire my brain but be patient with me.

"....A sequential shifter is a race transmission that works like a motorcycle transmission and is what race cars used after H-patterns but before automated clutches. Sequential shifter are ALWAYS forward for downshifts, back for upshifts."

Yep. I've raced shifter karts and motorcycles. The tactile environment in these vehicles is as different to a 718 as driving a riding lawn mower.

I've learned '9 and 3' is a great hand position - and it perfectly sets you up to have access to the paddle shifters regardless if where you are in the turn (not that I'd recommend shifting during a corner). This is where I put my hands on the track, and now even with daily driving in any car. No need to move my hands for any turn, unless you want to, of course.

The PDK has been awesome for me. It sounds like it's rev matching and it will not let you do a money shift. I know this from experience unfortunately. On the track it's been awesome to be able to hard brake into a corner and quickly down shift by 2 gears at a time (the corner I have in mind is a very sharp turn - the apex is behind you going into the turn in). I've also been guilty of forgetting which gear I was in and which paddle shifted up or down. Practice makes perfect, the more I use them the less I have to think about it.
