Default Dumb, Dumb, Dumb...Ever forget you are in Manual Shift Mode?

Well, I did it finally today. Took off from a stop sign (had a cup of coffee in one hand and hit the rev limiter in 1st, I was like why won't this thing shift and looked down and it was in manual mode...all seems fine but really looked kind of lame to other driver's around me...I'm sure they were thinking, what's fancy pants doing - doesn't even know how to drive his fancy pants car

I was next to you, and yes, that was exactly what I was thinking. Seriously though-isn't there an over-ride function as I can see myself doing something like that.

What's this manual shift mode you speak of?

Hehe, I _might_ have done that, lol. There is no real risk, though, me thinks, for the opposite money shift with rev limiter?

I did that on a test drive of all things. Forgot that I was in manual mode - the salesman was going "SHIFT SHIFT". I felt completely lame.

DUMB! My M5 is the same way - but never forgot that I was in manual mode.

If you floor the accelerator in manual mode without downshifting manually first, especially in the higher gears, PDK will automatically kick down to a lower gear. If you continue to stay on the gas, it will upshift for you at redline. In the Carrera tech manual this override feature is referred to as "panic shifting"

OTOH, if you start out in a lower gear and accelerate more gradually without causing PDK to attempt a kick down, you will stay in that gear all the way to redline until you hit the rev limiter, which is what happened to the OP.

Of course things are fine. You can drive it along all day bouncing off the rev limiter...that's what it's there fore. Damaging overrevs happen on manual cars when downshifting.

That confusion seem similar to happens to everyone when one first test drives a PDK with buttons. The foot, finger, eye, shift and feel circuits get toally overloaded. If it is on the auto side in normal mode the shifts come disconcertingly fast. If it in sport on the manual side, the redline (or objects in front of the car) arrive disconcertingly fast. Then when you figure that out it "learns" on you and behaves like you just did when you don't want to anymore. Then you forget which finger and direction shift up and down. Totally exhasperating.

PS live with it a while and all the shifting become options to whatever fun or relaxation you desire. Thats the 991 way.

EXACTLEY what happend, did surprise me that I was in Sport mode NOT Sport Plus mode and it didn't shift at Redline...seems like it should have shifted at redline in Sport mode and manual...live and learn I guess

Good point, you'd think even it would have shifted at red line since I wasn't in Sport Plus mode - only Sport mode. Can anyone attest that this is the intended function of the PDK in manual/sport mode taking of normaly from a stop? Seems weird...

Well said, I miss the driver involvement of my manual trans so much that I drive the new PDK in manual mode 95% of the time...not the best for mileage, but I need to feel the "sport" in sport car!!

I hear you. Just had my Porsche in for service, and I was given a Cayman with an automatic. I enjoyed it for about 10 minutes, but then I got bored. Just have to row through the gears to enjoy driving. I suppose if I were driving a Lexus, an automatic would be fine.
