Default Torsen VS Haldex....quattro split in TT

I know the new A4's have the power split 60-40 rear to front........but under normal driving conditions, what is the split in the MK1 TT when just driving around?? And then what is the maximum amount of power that can be transferred front to back and vice versa under spirited driving?? thanks!!!

Default in cruise mode, the TT is pretty much all FWD>>>

with the OEM haldex controller, i believe it maxes out at 50/50 bias till traction is reestablished...

Aftermarket controllers can change the reaction times and percentages of power distribution depending on the model chosen

Default I always had heard in the early TT's the Haldex was split 80/20 front to rear. The "new" controller

made it 50/50.

Default Can early models (01) be coded differently (or "new" controller installed) to alter the bias, or are

we stuck w/ 80/20??

Correct about cruise mode, but can max out to nearly 100% front or rear, according to Haldex folks

Default in which application for 100% rear? Most I have seen is 50/50 on the MK1>>

Quattro setup with an OEM controller....be curious to see that

Default

not coded at all, just replace the controller with the after-market one

Default The typical blue and orange controller upgrades don't change the static distribution

just when torque transfer starts taking place and also if Haldex is disabled during braking (for the orange)

I think Dahlback supposedly makes a 50/50 controller but I haven't heard of anyone on here or Vortex running it.
