PDK manual, would be nice if car auto-shifted up rev limiting
This thought came up during a recent track day.
I drive in manual mode when i'm at track. PDK auto is definitely quicker, but manual is more fun. inevitably i bounce the limiter from time to time. Its hard to look at the road and at the rev needle at the same time. i try to shift by sound. you drive to redline enough times and you can pretty much hear when to shift, but still i do tap the limiter from time to time.
wouldn't it be nice if even in manual mode, the gear shifted to the next gear automatically the moment before it hit the rev limiter? for me i think it would be a great idea to be able to drive in manual mode and not have to worry about hitting the limiter.
would there be instances one wouldn't want this automatic shift? are there instances where on needs to purposely bounce the limiter?
This would also be nice in a launch/drag race scenario. i like launching in manual mode but i'm always bouncing the limiter between 1st and 2nd as it's very difficult to get the shift time correct in that very short time between 1st and 2nd. if the car auto shifted before hitting limiter on 1st and 2nd, i can easily do the remainder of the shifting.
a good idea or not?

Have you tried manual override paddle shifting while in PDK auto. That would give you your fun of manually shifting, but would still allow the PDK to auto upshift without hitting the limiter if you are late.

Thanks for the tip

It will hit the rev limiter - at least it did in my .1 RS.

I'll tell you what I would love: for the PDK cars to have the gear shift assist option in the multi-function display.
I'm not talking about the triangle next to the digital speedo telling manual cars to upshift for better fuel economy, but the multi-function display option that shows the current gear as well as an indicator that turns yellow when the RPMs approach redline then switches to red when you really need to shift.

"Would there be instances one wouldn't want this automatic shift?" In general you wouldn't want the kick from a Sport Plus shift in the middle of a hard corner if you are at the limits. Actually, the automatic PDK programming has a feature that tries to avoid shifts when the lateral G's are high, according the to Technics manual for the original 997.2 PDK.
Gear retention while cornering
The lateral-acceleration sensor (single component with rotation-rate sensor), which is located under the centre console and works for the PSM system, is used to detect lateral acceleration and retain the engaged gear and lateral acceleration in the relevant gear, depending on the shift map.

When spring comes around and i'm back at the track, i'm looking forward to driving on auto but overriding with manual paddle shifts. lets see how that goes but the track is full of quick gear changes so I think even with six seconds before reverting to auto, I will have instances where i tap the limiter.
