Excuse my ignorance but what's the upgrade?-------------------------------------

its the first on the list of to do's when the car arrives....
from here
Technical details:
PreX is a newly developed system which broadens the product range of the Traction Systems division and complements the existing AWD system. Here is an example of where the performance tuned Haldex Performance Part excels. In the graph below you will see that torque transfer to the rear wheels during acceleration is much more aggressive with the new ECU installed. Increased torque transfer to the rear wheels during acceleration provides more consistent vehicle performance, as well as more neutral handling characteristics. In addition, the Haldex ECU monitors throttle input and transfers torque more quickly to the rear wheels when driving aggressively. In fact, how quickly the torque is transferred is a direct function of how fast the driver pushes the throttle pedal – The Haldex unit will actually anticipate and prepares for torque transfer before actual torque is delivered from the engine to the driveline. Lastly, all safety features will continue to function. For example, during ABS assisted braking or ESP intervention, the Haldex unit will smartly stop transferring torque to the rear to avoid any interference with the vehicle’s OE safety systems.Comment

PM LanceB. He had it done on his 3.2V6.
Apparently he loves it.
Why don't they ship with this 'better' haldex system? Why must we 'upgrade'?RIP!

Because you don't really need it in daily or even spirited driving...it's mainly for track workOriginally posted by 3Putt View Post2015 White German SUV

Guy.......with the Gen 1 upgrade, is it more or less set at the Sport mode from Gen 2 upgrade??
Surely it should improve times (both 0 - 100 and 400) as it makes the AWD more rear wheel bias....therefore 'should' give better push off the line. I may be wrong on that though.Comment

what sort of cost is involved ?Comment

Based on all the comments above it's now on my list of things to get.

I have the Haldex upgrade on my 3.2 V6 Passat wagon and can highly recommend it. The upgrade transfers more torque to the rear wheels through hard acceleration and that is certainly the case. In normal day to day driving it is not so noticeable, but start to give the car a bit of curry though the twisty bits and it the effect is quite noticeable.
The Haldex comes with a 3 position switch which can be set to:
Standard - the same as what the car is originally set at,
Sports - which is for normal day to day driving, and
Track - which is specifically for race track driving.
I have mine set to Sports and it is great.
They do not recommend the Track setting for street driving as I think it puts basically 50% to the rear all the time and is not so good for the car.
The Haldex is an exchange unit which takes about 15min to install. I also had a front centre engine mount changed to a urethane bush which also frims up the motor and stops a slight clunking with the DSG gearbox. Works very well. Maybe the R36 has better mount system than the 3.2V6?
The Haldex upgrade is well worth the money, IMO.Last edited by Lance B; 19-02-2009, 01:49 PM.Comment
