Only when I want to go fast.
I once got caught off guard when DSC was off, and it was scary having a turbo and an open diff. Needless to say, my girlfriends coffee ended up all over the window, door panel and seat. Learnt that lesson. |

Even having had an E92 since '07 and an F10 since '11, to this day I'm not altogether sure exactly what that damn DTC button does. I've pushed it a couple times to see what happens, and nothing much seemed to change. I know how to completely disengage the whole DTC/DSC system, but I've never done that.
All the best.

yep, i forgot which numbers it was to set it. But look up one push DTC on start up or something like that
I only have it set like that cos I personally think the DTC gets in the way when you go WOT in 2nd or sometimes 3rd gear (dont even try 1st).

Its not possible to tell the difference if you are driving normally, how ever try DTC on and off in the rain, with it on the computer cuts power and even tho ur foot it on the floor nothing will happen, turn it of and you begin to slide/lose traction and your car will continue to feed power. DSC if for eg, high speed manuvers, if there is something on the highway and you need to swervw it will brake each wheel individually to make sure you don't spin out(it also cuts power) I leave it on to bring my drifs back in line lol (leg go of the accelator and car brings it back). Someone correct me if I'm wrong

DSC by default (unless you have a JB4) is always on when you turn on the car. This stands for dynamic stability control. It is the most invasive of the traction controls and will cut engine power at any hint of wheel slip.
If you press the DTC button it will turn off DSC and turn on DTC (Dynamic Traction Control). This is designed for snow driving where some forward slip may be wanted. In this mode, it will allow some forward slip of the drive wheels and very limited later slip before cutting in and spoiling the fun. Holding down the DTC button with disengage both DSC and DTC meaning all traction controls are completely off. This mode is also called TIMYOYO (That's It Motherfucker, You're On Your Own). This mode will let you spin your wheels to your hearts content, whether forwards, backwards, sideways, 180s, 360s, into a tree, whatever you want. TIMYOYO is how I drive always, whether on the track or on the street, rain or shine. Be safe out there and know your limits before considering this option though.

Forgot to mention. All of the above settings are referring to rear wheel slip and limiting power to the rear wheels when attempting to apply more throttle.
The E-diff cannot be disabled at any time. ESP (Electronic Stability Program) is where the car applies the brakes to different wheels in order to avoid the car spinning when swerving at high speeds. This is a function of the traction control and most likely active when DSC and DTC are enabled but turned off when all TCs are turned off.

An LSD does this within the differential itself through gears and/or clutch plates etc. which is the more efficient way, but an E-diff is better than having an open diff with nothing at all. Quote:
Personally I drive with it off all the time and don't have those issues, even with 365rwkw and cold AD08Rs. In the dry I can spin the rear 265s in 3rd and if it's wet it would probably do it in 5th but I've driven my car enough in all conditions to know when it will and won't lose grip so when I have it on TIMYOYO and it loses traction, it's because I made it do so. On purpose. But regardless of what I say and do, it will always be safer to leave it in at least DTC.

Just to complete Lemons research into this topic which currently is heavily weighted towards the "off" camp, I drive with both DTC and DSC safely on because I wear a hat and play lawn bowls on the weekend
