The STi's haven't had a yaw rate sensor untill this year when the JDM cars got it, but it was never officially stated whether or not the USDM cars got it or not. It's all part of the changes made to the 05's..

Well, then I need someone to tell me how the auto mode works on the DCCD.
AFAIK, the car "senses" when the car is in hard turns, and splits the torque bias towards the rear, making the car oversteer instead of understeer like the non-DCCD cars do.
As I said before, you need some sort of yaw or latteral-G sensor, or you need to watch for large discrepancies in wheel rpms (since the wheels on the outside of a turn spin faster than the inside). the problem w/ using wheel rpms is that if the car is sliding or spinning the wheels, that information isn't accurate. Plus in long, fast sweepers, the wheel rpms won't be much different, but a rear torque bias would be very helpful.
Who's got the knowledge to drop on us about DCCD?
