anyone have a TCU upgrade for a 997.2TT, remember hearing about one a few years ago but cant find any info. anyone make software for a PDK cars shifting patterns etc

Thanks

 

I am interested myself. New .2 pdk are faster , I mean both facelift panamera and 991 have faster and smother shifting . New zf transmissions in the audi rs6 and z06 a8 are getting almost as fast as ours , so I think we need a softwere upgrade.

 

I don't think the 991 PDK shifts any faster than the 997.2 PDK. It sounds like it does but that's all in the software/mapping so it fools people into thinking it shifts faster but it doesn't.

vBox runs tell the truth.

 

And there seems to be no cure to improve the response time of the older system in the 997.2.

 

Agree. And yes that's the most annoying part of the 997.2 PDK. When you pull the paddles there is a delay to when the shift is executed. But the shift time is very fast.

There is also a delay (between pulling the paddles and when the shift occurs) in the 991 but it's not as bad as the delay in the 997.2.

 

Stopped in to read this and I remember going to test drive my 997.2. I was hell bent on a 6speed. Then my salesman suggested I take the Pdr for a spin. Slid all the way up to a tts. Wow was it a fast shifting tranny. Now I'm used to it.

Just to echo what others have been saying, TCU tuning for the PDK would be such a big deal. Last night I drove my Audi and hitting the paddles resulted in instant, crisp gear change. Stock tcu but aftermarket ecu flash. I drove the Porsche back to back and was very underwhelmed by the pdk. It would also be great to increase the line pressure so the clutches hold a little more. Other platforms like VW/Audi do this so I don't see why it can't be done here.
COBB, are you listening?

 

Exactly. I get in my'13 GTI and am amazed at how much better the DSG tranny is.

 

As I have been waiting for 2.5 years myself checking and asking every day all over the net for any news, I literally just yesterday read over at rennlist that someone has cracked it in the States and just now I found a German tuner who claims the same thing!
Sounds like the real deal from where I am standing - only catch is that like with the tiptronics the tcu needs to be removed and sent over to be bench flashed.
Hopefully, one day we will have a Cobb solution like they have for the GTR guys,
but until that day we may have to try this tcu bench flash... If it works half as good as it did in the tiptronic it will be a revelation for me! Finally, raised torque limits and faster paddle response time like it should have been all along

Die verschiedenen Leistungen werden von uns individuell nach Ihren spezifischen Wünschen und Bedürfnissen programmiert und können (sofern mechanisch sinnvoll) individuell kombiniert werden.

 

And for those that do NOT speak German...here is an attempt at translation that should at least be pretty close:


This applies to all models with 7-speed PDK transmission

Until now we have this offered exclusively Porsche tuners to your customers needs.

From now on we offer all Porsche owners of the above mentioned Models special reprogramming / adaptation of the 7-speed dual clutch transmission also directly.

Our services in the PDK Porsche-remapping comprise in detail:
Adjustment of switching points - enable a higher max. Speed ​​(Nmax)
Adjusting the speed limitation
Adjustment of switching times (for example, switching time reduction)
Adjusting the reaction time of the shift paddles (shortening)
Reprogramming of paddles
Reprogramming the shift (+/- direction)
Cancellation / change of the torque limiter
Adjusting the clutch pressure (no slipping clutch, especially the turbo)
Deactivation / modification of the forced upshift in different modes
Deactivation / downshifting during kickdown prevent in different modes
Adaptation of the switching operations of individual driving behavior
Vote the Launch Control
Unlock Launch Control for vehicles without Sport Chrono and Chrono Sport Plus
Launch Control activation in all modes (Manual, Normal, Sport, Sport Plus)
overall improved switching behavior (for example, no shocks, smoother transition when switching)

The various services are programmed by us according to your specific wishes and needs and can (if mechanical sense) can be individually combined.

Kudos man!
Spot on with the translation

 

The factory computer can reflash the TCU. They flashed mine to the European tune, and I like it better. It holds the gears a little longer in Sport mode.

But as far as other functions like changing line pressures etc, that has to be left for the aftermarket.

And as far as the time delay between pulling the paddle to actually shifting, I find it's fine under WOT but there's more lag when partial throttle. Honestly it's a small thing for me. I've gotten used to it and it doesn't bother me.

I just hope someone can get the TCU reflash sorted when E85 kits come out for the 997.2. That's when you need more clutch holding power, etc.

 

Just found the tuner's English version of the product release:

For our international friends:
Remapping Porsche Dual Clutch Transmission (PDK)

Software modification of sportive 7 gear Dual Clutch Transmission
of modern Porsche models

Modern Porsche models from model year 2009 on are delivered with the sportive 7 gear Dual Clutch Transmission (PDK). Depending on different kinds of riding modes, it is equipped ex works with a sportive driving pleasure, fast gear changing, direct power transmission and at least a lower fuel consumption.
In special cases it is necessary to reprogram the PDK for individual driving behaviour, individual driving situations or the vehicle´s technical modifications (e.g. technical modifications for an increasement of power).

Thanks to our comprehensive knowhow especially with Porsche, we are glad to offer our remapping of Porsche PDK transmission, which was developed and intensively tested for the following Porsche models:

Porsche 991 (911) | 991 (911) FL | 991 (911) Turbo GT3
Porsche Boxster |Porsche Cayman 981
Porsche Panamera 970 | Panamera 970FL
Porsche 997 (911) FL from 2009-
Porsche 987 FL from 2009-
This applies to all Porsche models with 7 gear Dual Clutch Transmission
In the past we’ve offered this exclusive to Porsche tuners and their customer needs only.

From now on we also offer our service of reprogramming & adaption to all owners of Porsche models with 7 gear Dual Clutch Transmission as listed above.
Our Services for PDK-remapping Porsche provide in detail:

- Adaption of switching points – enable a higher max. rpm (Nmax)
- Adaption of speed limit
- Adaption of switching times (f.e. shorter switching times)
- Adaption of shift paddles response time (shortening to the reaction time)
- Remapping of the shift paddles
- Remapping of the gear levers (direction +/-)
- Offset/adaption of the torque limit
- Adaption of the clutch pressure (no slipping clutch, especially Turbo´s)
- Deactivation/adaption of forced upshift in different riding modes
- Deactivation/prevention of downshift at Kickdown in different riding modes
- Adaption of switching operations to individual driving behavior
- Tuning of Launch Control
- Activation of Launch Control for vehicles without chrono sport and chrono sport plus
- Activation of Launch Control in all riding modes (manual, normal, sport, sport plus)
- In total significant switching characteristics (e.g. no jerking, softer transition while shifting)

Our different services are individually programmed according to your special wishes and needs. If it is mechanically useful, it is also possible to combine individual programming services, whether if you need the reprogramming for a better driving behaviour at street drive or for a modified vehicle for driving on a racetrack.

Please send the specific dates of your Porsche, optionally built-in components, the desired range of application and the expected changes.
Additionally we suggest the remapping of PDK transmission in combination with power increasements that we also offer for different kinds of Porsche models. Do not hesitate to contact us for the individual possibilities for your vehicle!
As an official dealer of DODSON Motorsport we also offer upgrades of the transmission hardware in conjunction with our power increasements and remapping of PDK (adaption of speed limit / Offset/adaption of the torque limit).

Important: for all modifications, we need the PDK control unit (TCU) for 1 working day in our office. So if you send the TCU to our workshop and we will receive it on working days at 2pm at the latest, we will arrange back shipping just the same day. Please note: if customs declaration is necessary (shipping outside the EU), it will take up to 2 working days longer until back shipping). Express shipping on request.
