When I read this, I was surprised. My DSC unit is inside the passenger side (right side) cowl vent. Is yours there? Does it say "DSC" on it? Does it have 6 hydraulic lines going to it?

I'll post my MA's answer as soon as I have the opportunity to inquire. It's never as simple (or as cheap) as it should be though...

I'm interested in this question too! Anyone know?

from what i've read on the MTH, it will lessen the effect of DSC, causing it to only come on in the most dire of situations (ie spinout) instead of when pulling out of a traffic light too quickly...i have not read that it actually gives a non-dsc car dsc, and i highly doubt that would be the case...
but it is good for making the DSC less intrusive...

Oops - my apologies for getting this screwed up!
Sorry, everyone - I disremembered the stuff about DSC/ASC and MTH.
Apparently, if you have a car without ASC (a Cooper), the MTH-Powerchip will enable ASC. But NOT DSC, which requires additional hardware.
I apologize if I made things more confusing!

I don't care what electronics you have, tires make all the difference. Summer tires and most performace "all season" tires can't handle cold or snow.
I look forward to getting the DSC. The mercedes version saved me once when driving in Germany... Thanks for the winter driving tips with the stuttering on acceleration.

ASC uses only engine input (torque) and wheelspeeds to determine that the driven wheel(s) are not getting proper traction and either reduces torque through the engine or applies the brake to a slipping wheel or both depending on the circumstances.
DSC on the other hand also requires steering angle input (to determin where the drive wants to go), yaw sensor and lateral acceleration sensor. These addition sensors allong with the wheelspeeds tell the DSC controller if the vehicle is going in the direction the driver wants. If the car is oversteering or understeering, the DSC will apply braking pressure to one or more wheels and potentially request the engine to reduce torque.
In short, you would need to retrofit a steering sensor in the steering column, a yaw-rate and acceleration sensor located under the handbrake, and the DSC unit itself.

i kinda like when it kicks on from a red light...if u gun it enough to get it on but not enough to make it actually slow down the car, the MINI kinda 'hops' ... makes the S even more like Mario Kart on 150cc class...now if i could only find a way to get that power boost from the hop like in the game...or those invincibility stars...

I toggle off the ASC from time to time,it sucks getting going on ice,wheel spin is harder to control and everyone pulls away from me.With it on the car pulls better,does not lurch as bad if I hit dry pavement,and with snow tires,I find I can keep my foot in it more,and the light blinks,not on steady and bogging me down like with the all seasons.

CBC looks at the difference of left side to right side to determine if the vehicle is turning. DSC requires more information to get the proper vehicle dynamics and what the driver wants. CBC, ABS, EBD don't care what the driver wants, just what the vehicle can do while brakes are applied.

You pretty much asnwered your question. If you are into racing or other sorts of performance driving, you should not get the DSC. DSC helps you get out of trouble in emergencies, such as rain, snow, ice. It balances the car when the sensors find a wheel losing traction. I keep it on in my daily driving, and when I am on a Sunday run or autocross, turn it off, because you do not need to many electronics get involved, in sake of having full control on the car, drive faster.
Bottom line is, most likely you will not need it, but one time you need it, might be too late. Get it, not too expensive either.

It might not hurt - here's my reasoning...
Recent studies have shown that stability control systems have reduced the occurance of fatal single car crashes by like 50%. That is huge, on par with air bags and seatbelts.
So, it could be that in a few years, resale on cars without a stability control system will suffer. You might also start to see favorable insurance rates for cars with stability control.
I could be all wrong. My Mini does not have DSC, but had I known this before I ordered it, I might have gotten it. But I did buy the car specifically for autocrossing, and rarely drive it for anything else, so I guess I'm doing ok. Still wouldn't mind having it for the drive to and from the autocross, though!

Well for me it was money I'd rather spend elsewhere. Like for a LSD. I'm not a fan of electronic nannies on my cars. At least they give you an off switch. Wish the abs had one of those switches. When I need a computer to drive the car for me I'll give up & take the bus. Just my .02 here.

Although just to play devil's advocate, wouldn't an LSD just be a mechanical nanny?

LSD is mechanical but it is enabled all of the time to "help" you have the most traction as is possible. It acts to assist you, not override your actions like the DSC sometimes does.
DSC is not active all of the time, only when it senses loss of traction- hence the "nanny" comes alive.

Curious about those times you'd CHOOSE to lock up your tires though...
DSC is cheap insurance. Much like car insurance, you hope you never use it. Unlike car insurance, you only pay for it once.
You may be able to see every slick spot, bit of gravel in a tight corner, or oil on the road. Then again, you may not.
A nanny tells you not to do things. The computer is more like a kind aunt who doesn't tell your mother you screwed up...
So why is this thread in 2007 mini talk?
