The "eLSD" remains active no matter what you do with DSC, TC, etc. I'm unaware of any hack for that would disable it. I believe this applies for all recent BMWs with an eLSD feature. Which I believe is all non-M BMWs. Not 100% sure on xDrive, but I suspect they use brake driven eLSDs to some extent as well.
If you can get the car to do burnouts, you will spin both tires due to the eLSD working. Along with wheel hop. How well this actually works in making your car do cool burnouts will depend on the surface, your tires, air pressure, etc. This does not mean the eLSD is actually all that great. It will still tend to spin the inside tire powering out of corners in real performance driving situations, and the eLSD is often very ham-handed. It will overcorrect if one tire is spinning too fast compared to the other, effectively cutting power, making the car buck, etc. Using the brakes to simulate an LSD effect just simply isn't as good as a true LSD. Just because both tires spin doesn't mean it works as well as another "true" LSD. That's one of many countless situations where we can discuss what an LSD does and rate its effectiveness. Ticking the one box "spins both tires in a burnout box" is NOT telling the whole story, or even most of it. You can argue whether or not the eLSD being part of the car means you should make statements like, "the car has an LSD." Typically in this forum people do not equate "eLSD" with "LSD." Most of the time people mean a real "mechanical" LSD when they talk about LSDs on BMWs. Meaning the only BMWs that "have an LSD" are M models or much, much older models before BMW stopped giving non-M models LSDs.

When a true LSD is swapped into our cars, what happens to the eLSD? Since it is a function of the brakes, will the LSD performing as it should satisfy the computer in not wanting to correct for anything?
In other words, after the install of a LSD, does the "eLSD" essentially not interfere anymore? |

I can confirm it will leave two strips with the stock open diff Last edited by Nugget; 12-16-2014 at 10:07 PM.. |

No point in coding out. In fact, it is probably still a good thing. I plan on installing the Quaife Sport Diff. I have had 4 cars with Quaife diffs and really like them. Only draw back to them is if you hit a curb and the inside wheel comes off the ground, they act like an open diff. The eDiff should provide enough friction to that wheel to keep the Quaife working.
Win/win in my opinion. Plus, then I will have the 3.48 gear in the back, an instant increase of nearly 40 lb.ft to the rear wheels! With a friction type LSD, I doubt the eDiff would ever do anything. |
