In DTC mode (one tap of the button) the car now allows a good deal more yaw and a little more wheelspin before stepping-in, and when it does step-in it's a lot smoother than it used to be. It's my goldilocks mode that can be quickly enabled and lets me play with the rear end a bit more when I'm in the rain on my summer tires, or on some really wacky terrain that I know will cause issues. There's a safety net there, and it works well for driving on the street. I also had the wonderful opportunity to see how the car and the computer reacts on a skidpad, so when it does step-out, I'm comfortable with the recovery.

Here's a thread on the coding stuff, and it's where I found the 1M values:

Awesome! I didn't know you could do that.

I'm guessing you changed these four values:?

Code:
LENKWINKELKENNLINIE // Steering Angle Characteristic Curve
135i: wert_03
1M:   wert_00

UEBERSTEUERN_MUE_0 // Understeer Friction Coefficient 0
135i: wert_04
1M:   wert_00 (base value is wert_01, C04 value is wert_04, others are wert_00, not sure what the true value is)

UEBERSTEUERN_MUE_1_2 // Understeer Friction Coefficient 1 2 [DATA<128 ? COEFFICIENT = 2.5 + (DATA/64) : COEFFICIENT = 2.5 + ((DATA/64-256)/64)]
135i: wert_05
1M:   wert_00 (base value is wert_01, C04 value is wert_04, others are wert_00, not sure what the true value is)

UNTERSTEUERSCHWELLE // Understeer Threshold
135i: wert_01
1M:   wert_00 (C03 is wert_02, C04 is wert_04, others are wert_00)
