Disabling E-LSD??

[philaf_666]

Is there any way to completely turn off the E-LSD? It's electronics so it probably doable right?

I might be completely wrong here, but is this the reason why it's hard to do a nice smooth donut? Not that I want to do this every day, but I feel the E-LSD is blocking the way to do so.

The only RWD I had before had a LSD, so I'm not sure what's the exact effect of an open diff, but I've seen pickup truck and old mustang do nice donuts so I guess the E-LSD is getting in the way.

Again, I know donuts are useless, but I'm only trying to understand what are the effect of E-LSD, when it's in effect, when it's not, and if we can completely disable it.

And yes, I hold the DTC button for 4 sec. before doing so.

Thanks!

You can't turn the e-LSD off. Even if you could, you can't do a donut with one tire spinning, which is exactly what you'll get without it.

The e-LSD works by applying the brakes to the spinning (outside) wheel, which shifts the power to the other wheel. Obviously it isn't as effective as a true LSD, but it's decent for a street car.

So basically it all comes down to LSD... but how come an old mustang can do donuts? They're open diff, so one wheel spinning but still it works?

Could it be poor quality tires on the mustang that helps? Maybe grippy tires hold the car from sliding properly (i'm still on the RFT). Because even sliding around a corner is quite hard to do. With my old IS300 (LSD), it was much easier...

I know what the E-LSD does, what I don't know is when it's applied, and when it's not. I guess it's working through a certain range of speed or controlled by the amount of pressure you put on the gas... anyone knows for sure?

You have three modes.

Full DSC (default) - the computer will apply brakes at any/all 4 wheels, and regulate the engine fuel (eg shut off the engine) to do what it can to keep the car stable.

Reduced DSC - or DTC (by pressing the button) - this mode reduces the control by recognizing that the car is in slippery driving conditions. The computer allows for some wheel slippage.

TIM YOYO (Press the button for 5 seconds). Only the E-Diff is on, which will apply the brake on the inside (slipping) wheel.

Thanks, but that part I know for sure. What I'm asking is if in TIM YOYO mode we can disable the E-LSD and what difference it would make.

e-lsd cant be disabled. Why would you want to? What are you trying to accomplish?

Would a '77 Impala have had LSD? I guess it's possible. I used to do donuts all the time when I had snow. I could drive down the street at a 45 degree angle in that thing. It was awesome. If the car wasn't turning right because of rain or snow I could take my feet off both pedals and it would usually right itself. Ah Big Blue, how I miss you sometimes and your big fat tires that could take an impact without any trouble.

The reason an old Mustangs can probably do better donuts is the fact they have solid rear axles that don't grip the road very well. Good for donuts and drag racing, but nothing else.

Mustangs haven't had open diffs for decades. The vast majority of RWD American performance cars on the road have LSDs.

Then it's really a shame that our car doesn't have it! Plus it seem very expensive to convert to LSD because it's welded...

I would say that's the biggest flaw of the 1er (for me that is).

I understand the M3 market shares and stuff, but still a mustang has it!!??

Anyway, a still love my 1er

Under normal driving you wont notice it. Most of us aren't too concerned about 'donuts'

maybe you are not trying hard enough.

I'm not really concern about doing donuts, but since I'm swapping the crappy RFT soon, I thought I would try The result were not very good, same for drifting around a corner. I'm not saying that you can't do it, but it ain't as smooth as I would have thought. You can see it from the video that you have to push it real hard and that it's hard to maintain.

I'm actually just trying to figure out when the e-LSD comes into play and when not. And also how it actually affect drifting. Nobody really seams to know the answer.

Before my 135 and STI, I had an IS300 with LSD and drifting was much easier (even with 215hp) so I just wanted to know how much was related to the LSD.

Are you on the track? What opportunities do you have to drift?

My wife's non-turbo 2001 Subaru Forester has a LSD. Not really needed with only 165hp but it does help out in the snowy conditions.

Empty parking lot. Track. Every corner where it's safe. You don't like getting out of a turn broke side? I do.

It think it's a bit different since it's AWD (BTW, Subaru's system was awesome in my STI). But still a little frustrating that cars that don't really need it have it and a great car that should have it don't.

Thanks for all your answers, and if somebody knows exactly when the E-LSD is in effect and when not (is it speed sensitive, related to how deep the gas pedal is, or else) please advise

As I understand it: When the nanny feels a rear wheel spinning she applies the brakes to that wheel.

under normal driving I notice the open diff all the time, it's really my only big complaint about the car, the rest of the issues i have are nit picking little stuff

but that open diff is really crappy, I hate pulling out and spinning 1 tire so easy, and then it kills the throttle

if the roads were really good it would be a non issue, but we sure don't live in a perfect world

100% agree with you!

My advice would be to get a 240sx with a fartcan and a welded diff if you use your car for stupid shit like donuts...Its not like it takes any power or skill to ruin your ties lake a dipshit...

I really don't give a sh** about what you think of burnouts and drifting. Please answer the questions or keep your comments to yourself.

If you are such an expert, please tell everyone how and when the e-diff works and the effect it has on drifting. They are still trying to figure it out in the Track/Autocross section.
