Following mention in another thread in this forum, rather than hijack it:
There is now a ATB differential available for DSG equipped Mk5 GTI's. The Quaife manual transmission version has already been available for a few months. The DSG version costs £650 as opposed to £550 for the Manual - Both prices exclude vat. It's product # QDF19R.
ATB = Automatic Torque Biassing and is a development of the Limited Slip Differential.
Even with a Stage1 modded car and greatly improved suspension, it's still too easy to get the front wheels to slightly slip in greasy wet conditions (as the weather is now) on roundabouts, and that's without 'going for it'.
Apparently more torque gets delivered to the slower wheel and a 'softer' power delivery results. It works particularly well with DSG and TC, I'm told. It's guaranteed for life and is 'fit and forget'. The downside, if this is one, is that it weighs 10kg - Now, how much weight did I save on my carbon bonnet and big brakes? - Exactly 10kg just on the AP brakes. I suppose it's a bit heavy for Santa to put in my Xmas stocking.
The work does involve opening the DSG box and for that reason I won't consider this mod until after my warranty expires next summer. However, I will use JKM (my Revo tuner) who is very experienced at fitting such things as LSD's and he won't undertake it until he has researched it and feels 100% confident. He's even prepared to invest in any specialist tools as he's confident that Mk5 GTI owners will gradually increase their modding as the car gets older (and cheaper!).
The Ford Focus RS has a Quaife ATB and the Renault rival to the GTI has one too - All reports are glowing!

Ditto... it will probably be the last mod I get round to doing although I don;t think I can't wait for the 3 years to be up until I try... I will wait and see what happens to guinea pigs - sorry I mean respected forum members :grin: - like Red Robin and see what they report back. Also there might be developments along this line - i.e. a cheaper way to uprate the DSG box to handle more torque than just 350nm because its 300nm as standard and a remap will only give you 50nm extra as opposed to 110+ nm on a manual.

....This "respected forum member" isn't necessarily going to do it - I've got plenty of time to decide.
Most of the established good tuners remap to a limit of about 400 Nm / 300 ft lb on the DSG box on the GTI (not Ed30 version).

I wonder if the GTI box is the same as the Ed30? Probably?

Now I am really confused... I have read countless threads in other forums that say the DSG is limited to 350nm and this is why Oettinger also limit their remap to 350nm? I have also read that the DSG software prevents more than 350nm going through the box... :undecided:

DSG does limit the torque to 350nm...but only in first and second.

Really - that is sensible in a FWD car! And after that? :drool: :drool: :drool: :drool: :drool: :drool:

....My Revo Stage1 showed close to 300 ft lb (406 Nm) on the rolling road. I've had conversations with Revo and other tuners before I remapped because I was particularly concerned about how DSG would be - I researched this aspect over several months and waited until I was satisfied before remapping. During that 'research' I learnt that VW build-in approx +40% 'headroom' tolerance to their engineering on their official figures. So, if VW say 300, there's actually about 420 in the envelope.
Everytime I've done a mod, I've checked that torque isn't over increased to a level I don't feel comfortable with for longevity. I had the DSG Mechatronics Unit fail but way before I remapped. A remap transforms the GTI. With the same driver in each car I would say that my modded GTI has faster performance than both a stock Ed30 and a stock R32 but it's not all about being faster but having your own car as you prefer it as a ride.
I'm not alone in reporting that the DSG shifts feel smoother since a remap - Except when cold start.
In all the lists of differences I've so far read about Ed30 internals, I haven't come across anything yet suggesting that the DSG box is any different on any of the Mk5's.

The Ford Focus RS has a Quaife ATB and the Renault rival to the GTI has one too - All reports are glowing!
I thoght that clarckson loved the RS on the track, but hated it i=on real world roads, due mainly to the LSD.

You are right. He didn't like the agressiveness of the LSD in conjunction with the power delivery of the turbo :sick:
No boost, no boost, no boost, no boost, ohhhhh shiiiiiiiiiiit :shocked:

.... :confused: Since when has any LSD been "aggressive"? They usually smooth the drivetrain. Someone I know who has driven the RS says the Quaife ATB is "awesome".
I assume you mean the Ford's turbo delivers undesirably?
