DTC makes car slower?

RedStig · 05-20-2014, 11:08 PM

Is it possible that my DTC is making my car slower? as in more gas restrained. im not sure why but it doesnt react as quick lately, it does much better when its off or when dsc is off.

tc535i · 05-20-2014, 11:09 PM

My car revs the same, dtc just allows more tire slip before it shuts everything down

RedStig · 05-20-2014, 11:18 PM

its not a revving thing, its the lack of reaction

vapore0n · 05-21-2014, 06:57 AM

Yes it can.
It is very noticeable in the snow. The gas pedal will just barely work when you are sliding/slipping. The computer will take control to put you in the right direction. During better conditions, it tries to give you a smoother ride.

It is also for your own good, so you dont end up wrapping your car in a pole.

My car did learn my driving habits after a while. This improved pedal reaction and transmission shifting.
I would suggest driving the car hard every once in a while.

yeah but there is no snow here hahahah, i tried again today and im sure that theres some dtc malfunction cause even dtc off is faster

_Sinister_ · 05-21-2014, 08:13 AM

Have you tried with it completely off? Hold down dtc for 5 sec and it will be completely off, this way works better for me.

That's kind of like walking into a third world whore house and telling the hookers how you don't believe in condoms.

GMe90 · 05-21-2014, 08:19 AM

Please keep your DCT on. I don't want you all slamming into me or others on the road because you turned off the car's safety features. Thanks.

jcarv20s · 05-21-2014, 08:39 AM

Whenever I turn DTC and DSC off my car feels more raw, which it is since all stability is turned off but what I mean is it feels more attached to the road. Basically it feels like my old 05' Stg 2 WRX. If i'm in a fun driving mood and no one is around I turn it off. Otherwise poor conditions and what not i'm not arguing with the car.

NICKBRUM · 05-21-2014, 09:02 AM

Its hard for me to believe the DTC is causing the car to be sluggish. I however am still learning about the E9X platform. On the E46 the traction control light flashes and the car falls on its face so it's rather apparent. I see no problem turning it off to test. We are not talking about 500WHP cars that are are unpredictable. You would have to be asking for it to loose control. Obviously unless in a modified 335 or a M3.

You're saying you get slower throttle response with dtc off? Definitely never noticed that.

So before the mandated traction control in 2012 cars were crashing into each other cause they didn't have traction control????

Guess I'm gonna have to sell my motorcycle and an older car cause they don't have traction control and might slam into someone.

AzureHaze · 05-21-2014, 10:03 AM

Yeah...I'm pretty sure DTC is not the cause. Keep it on.

FrankyGTR · 05-21-2014, 10:12 AM

pffft me i turn everything off,my car is rwd with 400+ if you know how to drive you dont need DTC on for safety lol

They absolutely were. Especially RWD torque monsters. What do you think prompted the research of that technology?

Further, nobody is asking you to sell your motorcycle and an old car, which likely does not have the torque and hp of a rwd 335i.

DTC should be giving less of a sluggish result. When you activate (yes, activate) DTC, you remove the throttle modulation. When you disable DSC entirely, you take all electronic helpers away.

DSC - ON = Throttle modulation and brake modulation
DTC - ON = No throttle modulation, but brake modulation
DSC - OFF = No throttle modulation, no brake modulation

Why BMW decided on that terminology is beyond me.

tc535i · 05-21-2014, 10:18 AM

yeah, it's an awkward progression. DSC is either on, in "DTC" mode, or all nanny modes off.

i was just about to post this terminology lol i actually said it irght in the op.

MGT81 · 05-21-2014, 10:33 AM

Does turning DTC on actually change the throttle modulation? I just leave it in the default all the time. Is this true for the 6MT?

Wuttttt. I'm gonna have a fun drive home today. Hope there arn't accidents on the road.
