What is ASC

[wulley1]

All right, here's my stupid newbie question of the day...


I have a 97 328iS with ASC. What the hell does it do?

[El Presidente]

It makes you wheels not spin on launch and the car not spin out in turns.

works well in rain too

btw its called Automatic Stability Control
and i believe you can turn it off in some cars

[iantosca]

Yea, with my car (98 328i) you turn it on and off. When I turn it on you can actually feel everything get tighter. Definatly more traction ... try it out sometime.

[jllphan]

It actually does about seven things. It generally reduces wheel spin (specifically for wet weather) by electronically monitoring and altering throttle, brake, LSD, and the other four i cant think of. In the rain it is helpful, but if i start feeling a little , it instantly reminds me to turn it off prior to any further as it can prevent me from testing the limits of the car...

Wrong , it is called ACTIVE STABILITY CONTROL+ TRACTION

In bmw they come as ASC+T. Though usually on the button it only says ASC.

I thought it was some sort of traction control but I wasn't sure exactly what BMW calls traction control. I noticed that it seemed to shift power from the wheel that was spinning to the wheel that wasn't. It really seamed to do a good job of keeping the car start.

When you have set it off only the system interfere a little later. You can't turn it off totally!

die plz.

its AUTOMATIC

why would something you can turn off and on be called active?

so when its off its inactive active stability conrtol + traction?

anyways... same thing

oh ya and read that thread webb posted

thats asc+t

he said asc

i think asc+t is the one that cannot be turned off

Ok guy:

ASC - Active Stability Control

ASC + T - Active Stability Control + Traction

ASC when enabled it monitors the wheels and when one or both tyres lose traction because of the too much power being applied to the rear wheels, the computer alters the throttle and reduces the power to the rear wheels, to that the wheels regain traction.

ASC + T is all of the above plus traction... so when computer monitors the movement of the car and if the car starts to go out of line the computer applies brakes to individual wheels as needed.

There was a speacial on BBC Top Gear a few yrs ago with the E46...
And i do believe that both can be turned off!

If you want more info .. try Google.com

Look at BMW.com and insert ASC in the search beam. They show you also a video. I've found this at the dutch BMW site (http://www.bmw.nl/bis/page-1-4-1.html)

It does this by killing the fuel supply to the engine, so the wheel stops spinning, and once the tire stopps spining on the pavement, the sensors detect the wheel has traction because it's not spinning faster than the rest of the wheels, and allows fuel to the engine again. It does not convert power to either wheel (unless you have an LSD, in which case I'm not sure if it regulates torque to each wheel or not or the LSD is purly mechanical)

Just as a reminder, you can SERIOUSLY fuck up QUICKLY if you turn off ASC, Driving with traction control on all the time dosn't let you get acclimated with a car's ability to loose controll. I usually ALWAYS drive with it on, and if I want to slide around in an empty parking lot, or drift, THEN I will turn it off.

I have a 95 318is..
Traction Control- How do I know whether or not mine has it?
Do I have ABS?

[El Presidente]

ABS was standard.
