Pushing once DTC does a lot of things. Not only, the driving wheel (RWD) can spin more, it allows the ESP to be less sensitive and the car can be put at angle, drifting. Specially fun as hell on wet.

I wonder what competitors have something very close. If it has been discussed I missed it and can't find it.

Pushing it again turns it off completely

[John 070]

I've never really followed the threads, but there seems to be a mystique about the DTC, as if when you take it completely off, your 335 turns into a beast that goes off the road....why?

[Saintor]

What I am interested is NOT to put ESP off completely, just to see what car companies have an 'half-mode' like BMW.

[whoosh]

Most traction systems have an intermediate setting between full on and full off. The real question is whether a company allows the system to be defeated entirely, which is not always the case.

[BMWCOUPE]

Random question but can someone give me a step by step or video of how to execute a correct and professional drift.

[ndog14]

Yes, other car companies have buttons like these. They're called 'Sport'

You have to be specific. And make sure that ESP is set differently like BMW does. Most of these 'Sport' buttons are about suspension and transmission.

[cole92]

Mistu and Nissan have been doing it for years. There is also mechanical systems that function similar to being "half off" like a mechanical LSD.

And traction control, abs, and stability control. I'm not going to list them all, but I can tell you most of the brands are Italian and German.

[Saintor]

Again, it doesn't help if you have nothing specific.

Mistu and Nissan have been doing it for years.

They have a mode that ESP is maintained but not as sensitive as normal? What models/year?

[ndog14]

The DTC button when pressed allows more wheel spin before traction control kicks in. It can either be used for getting up a hill in winter or acting like a "Sport" button. DTC stand for Dynamic Traction Control. Please stop saying ESP. Holding the button turns off traction control and dynamic stability control. Those are the only 2 safety systems operated by that button. ABS is on 100% of the time. The only other way to turn off the other safety systems in the car is pull the fuse, and it turns off ALL of them.

That's incorrect. ESP 's sensitivity is changed too.

[Q4P]

whatever it is; it's terrible...

It's designed for safety and not for fun, in my mind the system is still far too intrusive. This is especially the case when you have an open diff rear wheel drive BMW as almost all are.

You cannot take a proper turn or drive through a turn without being intruded. If you turn it all off; then you have the infamous hind and slippery legs of an open diff.

I disagree. Don't confuse regular mode and DTC on. When DTC is on, it doesn't kill the fun and it allows drifting at an angle. Car&Driver wrote about BMW's DSC "finally an ESP with can live with". I wouldn't want a RWD car without it. Of course you can turn it off completely but in most of the situations space is limited and having a net is a good thing.

I'll put it to you this way Saintor... you have a 323i so you're car is not nearly going to be affected by wheel spin as mine. I have the most aggressive Procede Maps loaded on my car that probably produce 390 or so foot pounds of TQ, sometimes a touch of the gas pedal will spin the tires and in a turn a light tap of the gas will stop you. What the car needs is an M mode then again; that is only for M cars...

About everywhere here there is snow and it doesn't take much HP to spin badly. I use DTC on a daily basis and when there is nobody around, there is a good chance that I am drifting.

[Saintor]

Now back on subject to finally have that old question answered.

ESP, electronic stability program. Another way of saying stability control. DTC only affects traction control. That's why the button is short for Dynamic Traction Control. FFS.

From the manual, page 88

DTC Dynamic Traction Control

DTC is a version of DSC in which the drive output
is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The system
assures the maximal drive output, but with
reduced driving stability. It is therefore necessary
to drive with appropriate caution.

You may find it useful to briefly activate DTC
under the following special circumstances:

> When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or starting
off in deep snow or on loose ground

It let's the wheels spin more before it kicks in, same way as a 'Sport' button would.

[Saintor]

No its doesn't

Here is what the DTC really does.

See note attached to 'Yaw moment control'---> 'Control thresholds increased', meaning that ESP/DSC kicks in later than in full DSC mode.


• CBC Corner Brake Control
• EBV Electronic Brake Proportioning
• MSR Engine Drag Torque Regulation

Here is a part of an answer

Sport Chrono pkg is 960$ option on many Porsches. Might includes other features I guess.

My Volvo AWD S60R had the ability to partially reduce DSTC or remove it completely - pressing it once partially reduced it, and then pressing it 5 times in a row completely removed it and you'd be able to tire spin.
