On BMWs, is it just a fancy word for traction control or are that actual electronically controlled clutch pack int he diff?

Somewhere I'm the middle. It's an open diff, but it mimic an lsd by applying the rear brakes independently to shift power

Thanks.. it's not true eLSD. It's just traction contol.. That blows!

In a way yes, but the eLSD is only active when traction control is fully turned off.

If it's an open diff and they're just braking a wheel to transfer power to the other side.. it sure sounds like traction control... then marketing it as eLSD.

I'm not disagreeing with you, but the way the car handles traction control and the eLSD are different.

Traction control will effect front(?) and rear brakes to minimize any traction loss. It will also cut power as needed. No car rotation permitted.

Turn traction control completely off (push and hold) and eLSD is active. It will only effect the rear brakes and it will tend to brake the inside rear to help rotate the car and minimize inside tire spin when exiting a corner. Power will not be cut. Car can easily power oversteer.

eLSD is not simply traction control. That's why traction control has to be fully off (and eLSD active) for launch control to work.

This whole 'e-LSD' thing - while certainly useful in cars with no true LSD - makes me wonder about any possible interference with LSD when mounted on our cars. I have M-P LSD, and would like to know how the two interact when ESP is switched on completely. Is LSD quick enough to do its job first, so that the inner wheels doesn't spin and for this single reason, the e-LSD has no reason to to apply braking? And with M-P LSD only offering 30% lock-up at acceleration, under certain condition that inner wheel starts spinning - can e-LSD be considered as helping true mechanical LSD past that point?

LSD takes precedence over the eLSD. So eLSD will only activate if you drive beyond the limits of the LSD. Assuming you have traction control fully off.

FYI you can code out the eLSD if you have a mechanical LSD installed (I did).

That's what I mean, Anthony - plus I'm contemplating the option of switching e-LSD off completely (via coding perhaps?) once a proper mechanical LSD is installed. It would be much more predictable, and - especially with the lockup ratio higher than 30% - much more efficient.

Is it clearly and noticeably better now?

[Dylan86]

I've always wondered about this type of intervention with the eLSD, curious if anyone with a mechanical LSD has experienced this, in a negative way? I haven't noticed any interruptions, personally, but haven't done full blown drifting in a parking lot to find out, either..

Did this change from the way it was done in the e series (eg e82 135i) cars?
e-LSD was always active on them unless coded out.

So, can any active member post coding to turn off eLSD?

Thanks

Thanks.

A lot of holes in and ? In that coding.

Do you suggest making the known changes if one has LSD?

Probably ask the OP on that post or ask for advice on that thread from somebody that had done it

Only change the things you know
