Just for reference:
Since Autocross tracks change every time, one can't compare times before/after. But comparing my times against the "usual suspects" (other drivers that are usually running similar times), I would estimate LSD made about 0.5s-0.75s difference on a 60s lap. What's your complaint? |

True, on a road course the tight turns where LSD fixes inside wheel spin are less important, and half of them are throwaways. But they're so much more fun with limited slip. In high speed corners, LSD improves stability over bumps and curbings and makes throttle steer much easier, especially power oversteer. I don't know about lap times, but for me it's a much more enjoyable driving experience that justifies the cost.

Feel is very subjective. If someone spends several thousand dollars on a Mechanical LSD human nature dictates that he will feel a significant improvement. The question is, who are you racing against and what are the rules? Does a mod like a mechanical LSD put you in a different class? To me a lot of the mod scene is not about racing but more about acquiring things and modding for modding's sake alone. If it is enjoyable do it. That is the pursuit of happiness. Some of this arguing seems pointless.
In my view there is a lot of enjoyment to be had by seeing how one's own skills improve without changing the car.

On a tight track I've managed to leave two black wavy lines for 50 metres out of a corner so the eLSD seems to do something

Having now driven both I can say the Mechanical LSD trumps the ELSD. That said, the ELSD trumps open diff for sure.
The Elsd feels so passive while the Mlsd feels active. The Mlsd lets you keep the tail out as long as you want. Also, the Mlsd seems to deliver power in the turns better then the Elsd. This is my first hand experience. |

On hard launch, my 135i launches powerfully and smoothly, and goes where I direct it to. It doesn't launch arrow straight at times, but it's far from lurching left to right. Maybe something is wrong with your car? Your power delivery is unpredictable? Other than the slow throttle response, the power coming from my engine is easily predictable with my throttle use. I've never been surprised by getting power when I didn't ask for it. I used to have a slightly modded Plymouth/Mits Laser/Eclipse turbo FWD. Now, launching that car was literally a hand full. It has an open differential, and on hard launch the front would shoot and dart left to right, and you really needed to have a good grip on the steering wheel under full boost. The way you describe your car it sounds downright dangerous as it's out of control swinging left to right and giving bursts of power that seem to come from nowhere. That does sound dangerous. But, compared to my experience, that description isn't universal. |

Might I ask how you managed to obtain all that telemetry? I wouldn't mind that sort of info to take back home from the track and analyze how to improve myself out there. |

I once had all the nannies crap out on me, and the car was uncontrollable when attempting to drive it as I normally would. I had to granny it from a stop or it would just spin a wheel in place, take corners very carefully or it would spin out, and keep it below 65, otherwise a scary shimmy would develop.

So, my guess is, - either only x35s have them, or amount of braking is very moderate. Also, I remember reading somewhere that ADB single wheel braking works on speeds under 25 either mph or km/h. Last edited by accel; 03-12-2014 at 12:10 AM.. |

Does the 1m and m3 have the E-diff?
Is it possible to code the e-diff away? If the 1m doesn't have it its should be possible, right?
I have the m3 diff mounted on my 135i and i want to do a burn out with out the brake system forces my rear wheel not to spin! |

I have not found out how to code it out yet, but it hasnt kicked in once to my knowlegde even with the pouring rain we had in New York yesterday. Maybe there is a fuse to pull to shut it off?

Has anyone figured out how to shut off or code out elsd yet? From my experience, shutting dsc and dtc completely off does not stop elsd or electronics from using the brakes, throttle cuts, timing cuts and boost reduction to keep the car in line under heavy throttle especially with high boost applications. Going WOT from a stop leads to power reduction for me mostly in 1st gear with all nannies off verified through logs. I also have a mechancel LSD installed.
