LSD and Donuts

For those who have LSDs, are you able to do skidpad exercises, donuts and figure 8s?

Just checking, cos I have a real hard time doing those, it's as if the traction/ESP is never completely off even if you turn all off. Other drivers watching me mentioned they heard the brakes pumping, so do I, but not sure whether that is a figment of imagination.

Anybody?

If there is a fuse which powers the DSC/ABS system, pull it and retry these maneuvers. I'd almost give up the ABS to avoid these problems.

The car has a two stage dsc, are you seeing dsc on your dash or the triangle with the exclamation mark?
If you see dsc, keep holding the button until the triangle appears.

That's not it. I indeed turn everything off (5 seconds)

Here's a thread with the fuse panel diagram - try pulling the ABS/DSC fuses and see what happens. See if it helps your computer-intervention problems.

Worst case, you put them back.

Haha oops I forgot to cut/paste the thread with the fuse diagram. Thanks BFLY.

Thought it might have been that simple. Too bad it's not!
This thread has fuse diagrams which should help.

How are you sure they are completely off? Are you able to do nice donuts or figure 8s?

yessir Maybe your not revving it high enough. When i had my lsd installed the 1st thing i did was print an enormous number eleven in the road. I'm assuming your dash says DSC OFF. One other way I know mine can turn off completly is that I had it dynoed. You cant dyno a car with any traction or dsc on.
