Stability Mgt and Traction Control

Was it ever possible (in prior software versions) to turn off stability mgt and/or traction control - not for slip start but rather for performance reasons?

I'm curious if this was taken away or if Tesla has for some reason always felt the need to have them active.

Thanks.

The only thing I can recall, was a video and references here on TMC that dealt with the physical removal of a fuse in the fuse box.
With the fuse removed, the Model S was able to do incredible burn-outs.

You can disable traction control by a setting in the controls.
You cannot disable electronic stability control without pulling a fuse, which in turn also takes out a few other components (power steering comes to mind).

Bah. It can't be a drivers car without letting the driver take control when he/she wants.

Yes, it was and still is, on some Teslas.

Going into the lower left hand 'Controls' tab, and selecting 'Driving', it may be all AWD "D" owners who now see 'Slip Start' in the upper left. The option for an on/off slider going to 'Traction Control Off' used to be where this new (very) low-speed feature was added.

S85, P85, P85+, or possibly all RWD Teslas have the option for "Traction Control Off" (unless it was updated out?). In snow, with TC-Off, it is pretty easy to tell the front Stability Control remains engaged, while the rear slides freely. With TC-on, the car slows down, and allows less throttle to dig into the snow at an angle (keeping it on the arc of a curve, instead).

Jason C., of Road & Track, made reference to the P85D TC, saying "I turn the wheel and the computer pulls the plug",when he went to Lyme Rock, Climate Change: 2014 Tesla Model S P85D

Traction Control systems can look for other things than whether wheels are all rotating at the same speed. In valet mode, for instance, there is no slip before the hot-shoe Valet looses power. While that might be a good thing, it is possible for some of the same limits to be triggered by the position of the steering wheel, speed, a g-sensor, or something else, possibly well before the owner loses grip. This is where making a safe car, and a performance car, can mean different things. Drive modes can make everyone happy. :love:

I can confirm that even when TC is turned off in my RWD car, the rear will not slide freely. The wheels will happily spin, but once the back of the car begins to slide to the side, the car will apply ABS braking to specific wheels (front and rear) to square the car back up in a straight line.

On my S85, "Traction Control Off" is absolutely essential to make the car move with certain types of snow conditions (thin layer of very wet crunchy stuff, going up hill) Otherwise, the car stopped and wouldn't go forward. It's actually essential Stability control remains engaged. The switch is still there as of the latest version of 6.2.

This is the issue. It's a small nit that I have with the car.

As I said in my lengthy post about my experience with the car I want a Model S and a GT3 and then I won't complain too much.

Me too. The end of my lane road is a 180-degree turn into my garage, and in the snow I prefer to turn the wheels to the right and just give 'er hell to make the rear end spin around - having a little controlled fun. Unfortunately, Tessie says "no" when the rear end starts to slide, regardless of where the front wheels are pointed. Foiled!

That's too bad, and I hate to think it might have been changed with an update but suppose that's possible. In snow, you can hear the ABS engage the front, for stability, but I heard nothing from the back. That was January. With the P85D, there isn't much telling whether it is about to understeer, oversteer, or crab, coming out of a (dry) turn. After you've entered, you really can't get there. More than half the fun of having power, to a GT3 owner, is learning to apply it between the apex and the straight. Not just the lion's share of it on the straight away. Houston?? I'm not talking about sliding. That comes after you've found the missing power. If you open the steering wheel from, say, 90 to 45 degrees, and apply the throttle and find none, you aren't close to sliding. You've been shut down. This car should be leaving orbit, converting lateral g's to forward acceleration.

This has been the behavior since the day I got the car in 2012, I tried it that winter.

I agree with you, I hate how flat it falls on its face and would really like the ability to disable ESC.

Agree with tstafford. Is a big hesitation from purchasing. Going to keep my Carrera 4s for now. I understand Elon wants to keep these "safe" but really need a sport stability update...I'm sure the coders can create a similar "Side slip control" or "sport plus" for owners that want ability to play. Maybe the upcoming electric GT racing series will help this out.
