BMW Yaw Control
Does BMW use Yaw control? From my research it does it by applying it by ABS.
After driving around for sometime in a tuned BMW, sometimes when something goes wrong the cars computer will kick in but the tune will still behave the same. Will a tuner incorporate or read yaw control to then apply boost whenever needed?

Huh? DSC will attempt to control yaw in case of a slide by modulating the brakes at all four corners. Find a big open parking lot in the rain and try to slide it, you'll see.
As far as being related to tunes, I'm not even sure what you're asking?

Will a tune lower boost or turn off completely when DSC is involved controlling YAW?

I am fairly certain this is a throttle plate activity, but the short answer is probably "it depends on the tune"

I was under the impression that active yaw control had more to do with normal cornering and body roll, and how the outside struts would adjust to compensate for the cornering inertia? not neccessarily when the user input is demanding sharper turning angle than the car can deliver, triggering dsc

As I said above, I believe DSC "yaw control" is done with independent braking.

Shiv will you incorporate this in the future of the Procede?

We'll still to exposing ourself to the acceptable problems ("hey, my SES light didn't blink when I switched maps!") than bad ones ("hey, I crashed my car into a tree because the traction control applied too much brake to the rear outside tire!")

Not at all what I meant on the traction side. Basically have the tune read what the traction is doing and adjust boost and features that the Procede supply.

Do you basically want the car to drive itself? Just take your car to a track (not drag strip) and learn how to drive your car.

I do 100% of my driving in the streets, as probably everybody else. I thought yaw control was the vehicle measuring longitudinal and lateral g forces, steering, brakes and throttle position.

I've taken track lessons in Europe on different kind of cars(160€+) and difently know how to drive in different situation, cornering, shift points, throttle. BMWCCA here is to expensive.

A real track has turns and requires some skill! Hint: it's what the engineers designed these cars for!
