a post on the e90 forum, has anyone tried or noticed this on the e60? pretty cool and interesting..
"So, I took a road trip last week headed East just to see what I could see. I decided to drive south down Skyline Dr out of Front Royal VA, which seamlessly becomes the Blue Ridge Parkway when you reach I-64 in VA. Skyline Dr snakes it's way through some National Park, so the speed limit is 35 MPH. I wasn't in a hurry and just wanted to enjoy the road and beautiful scenery, so I set the cruise at 41 MPH, rolled the windows down and popped in a good CD. HERE'S WHERE I DISCOVERED SOMETHING WEIRD! With the cruise set at 41 MPH, every time I rounded a tight corner, just as the tires started losing grip, the car applied exactly the right amount of brake and/or cut power JUST ENOUGH so the car went through the turn without losing control! So, picture this...heavily forested two-lane perfect black top road with tight corners winding it's way through the mountains...up ahead you see a 90 degree left hander...cruise set at 41 MPH, left foot covering the brake, it seems like you're going too fast, but all you do is just steer left - perfectly planted, just the right speed, just the right amount of intervention and the car automatically resumes the set speed the moment you exit the corner! It's like the car was in some unholy "remote control" setting. Next up, the Blue Ridge Parkway, speed limit 45 MPH. Set cruise at 51 MPH, same deal! I don't know if I'm describing what happened well enough, but it was simply awesome not having to ride the brakes entering each corner, then accelerate out & all the time nervously checking the speedo to maintain a reasonably legal speed in the park. Previous cars I've owned would have HELD the set speed through the corner and right off the road as the car under or over steered. Or, the traction control would have kicked off the moment impending disaster was sensed. Anyway, if you have the Steptronic Auto and have the opportunity to experience this driving harmony on the right road, I know you'll be impressed with this little trick your car can do!"
huh?

My Ride: '04 530d Executive, all options except sunroof and comfort seats
ECU remapped by ZipTuning to 260+bhp.
I dunno... The E90 is equiped with newer electronics and computers and this just sounds like the DSC is kicking in, had nothing to do with the Steptronic.
When the DSC kicks in, you're clearly going way too fast and there is only so much electronics can do to keep the car on the road.
It's fun to try at reasonable speeds, but i wouldn't count on it every time i enter a corner.

In additional to reading vehicle speed, Dynamic Cruise Control also uses information from steering wheel angle, lateral accelerometer, DSC sensors to reduce vehicle speed when laws of physics are about to be exceeded. Intervention actions include the usual throttle control and add Dynamic Brake Control.
Active Cruise Control adds laser ranging.
Steering wheel and front wheel alignment is critical in modern BMW vehicles, even in vehicles with just Adaptive Front Lighting. Four-wheel alignment and steering angle zero reset should be performed on a BMW Kinetic System.

It's one of the reasons these cars go through brake pads faster too!
