Struggling with PDK

BTW, does anyone else find (pretty much) perfect rev matching on H&T these days more difficult than in the past? I'm thinking it's to do with the lack of direct throttle linkages these days. There doesn't seem the sensitivity. What do you reckon? Is it just my old age?
I agree with you. Cars with drive by wire throttles seem quite a bit less sensitive/responsive to a blip.

Can anyone with PDK tell me if when in manual mode the car will automatically go up a gear if you are too far into the red?
My fear is exceeding the rev range. In my mate's Z4 the gearbox takes over at the optimum rev range thus preventing you from exceeding the rev range.
Unfortunately this was not something I was able to confirm on my test drive.

It is designed to but there have been instances of overevved engines with PDK cars despite people saying it is not possible.The other possible scenario when it would be possible to over rev is when descending a steep hill in a low gear and the gradient and increased engine speed exceeds the limit.

But surely managing to over rev a PDK box takes a special kind of stupid?

Yes it doesThe difference with PDK (and the main cause of over-revs in manuals) is when trying to change down a gear.
If you were say in 3rd at 7000 rpm and tried to change down to 2nd, it won't let you. It will only change down if the resultant revs are below the value of the limiter.
In short, you'd be doing bloody well to over-rev a PDK even if it is theoretically possible.

It won't go up a gear if you're simply accelerating up through the rev range. It will let you sit there bouncing off the rev limiter. But that's not a problem as that's obviously what the rev limiter is for whether manual or PDK)
Maybe I misunderstood, but I thought exceeding the rev range was the same as sitting on the limiter (or anywhere in the red). Is this not the case?SV_WDC said:

Somewhere in this thread somebody mentioned that if you hold the left paddle it will drop to the lowest gear possible. I've tried this and nothing happens.
Can anybody confirm whether holding the left paddle should get the PDK to drop to the lowest permissible gear?
Thanks
Yes it works but I'd rather press once for each gear which has the same effect with more controlCan anybody confirm whether holding the left paddle should get the PDK to drop to the lowest permissible gear?
Thanks
