PDK calibration?

[cozzykim]

The take up jerk between foor off the brake and onto the throttle from stationary in my car is annoying me, it's especially bad when moving forward slowly in traffic (my wife thinks it's my fault) and I'm thinking that a PDK calibration might help, (strangely, it's a much smoother take up in sport mode, and doesn't grab/jerk at all).

Is it better to ask someone like MLR Porsche (local-ish to me) or is there someone around Uttoxeter/Stoke etc with PIWIS that might be able to do it?

Thanks.

I think there is a PDK reset procedure you can do yourself. I m sure I did it on my last one, I found a guide on YouTube.

It is supposed to reset it back to factory so it can learn your driving style, it may help 👍

Needs a PIWIS.

I asked the question after googling the problem and watching that video. 👍🙂

I thought that's the case too, but learning 'my' driving style will probably make it worse. 😂

If it's the AC one and raise one foot in the air etc not sure it works. Happy to be schooled mind.

I'd also start with getting the car read on PIWIS rather than jumping straight to a calibration.

Sorry, probably me being stooopid as usual, but I don't know what that means? EDIT: I found out what you meant by searching 'reset PDK' and I'm right, I am stupid. 😂

I've just been told by a specialist company that all PDKs do this, and that they have to be careful when moving PDK cars around the workshop for this reason.

Apparently, it won't do it in sport mode because the initial revs are slightly higher.

Is it definitely in 1st gear just before it happens or is it in 2nd and the jolt is it dropping into 1st? Where as in sports it's already dropped to 1st so you don't get the jerk?

Not calibration, but I updated @Patt s PDK software a couple of weeks ago, and he seemed to think it had cured this issue.  It took about an hour, as it programs the PDK, DME, and Instrument Cluster (why?) with the latest software.

Good point, I'll check that. 👍

That sounds interesting in its own right 👍

The reset procedure worked on my friend's car, he was complaining about the shifts after it has sat for a long while in lay-up and it worked! (remarkably).

Have a read.

I'd try this before updating.

I just got schooled.

Didn't think that was a real thing.

It worked on my Black Edition, it had spent its previous life in London traffic and the gear change was slow but after trying the reset it was much quicker and smoother. I wasn’t sure if it worked on the later cars but it appears it does.

[cozzykim]

Thanks gents, I'll have a look at this first and report back. 👍

[cozzykim]

Just been outside and followed the instructions.

At first and, as is usual for me, I probably overthunk it and turned the fan speed to OFF as well, so that the red light on the switched off air con went out.

I thought that this might defeat the process, so I did it all again.

Let's see how it goes...

[Patt]

indeed Richard - fixed that issue and a very smooth box ever since..if only one of the OPC that had worked on it had updated it when they should have !

Much appreciated for your help, now need to talk to Cobb to get that talking to the PDK too.

Sorry, I forgot to answer this. 🤨
It's in 1st when it jerks.

I've now reset it and it seems to be a bit better than before, though that might change as it learns my driving style again.
