No fella I mean the improved gen 2 controller, not the stock one on your S3, there is an improved one you can fit that does a better split of power for the rears. awesome do it I think.
The Stock 8P Haldex is improved over the stock 8L Haldex , with quicker reaction times and less losses.
I'm not sure if it has a better split of power.
The face lift S3 will be better again than the pre face lift, but the Gen II HPP controller will let you have a more aggressive split of power and has 3 settings. normal , sport , and race modes.
As far as i know the pre face lift 8P S3 uses the same Haldex unit and settings as the face lift 8P S3.
Phantom, can you post some info about what you just said ?
I read somewhere that the facelift S3 uses the Gen 4 Haldex, so it's a completely new system, including the controller. It could be wrong, but I definitely read it somewhere.
