I can tell you that it works perfect everytime and you can turn it off if you don't want it. The only frustrating thing is I find myself trying to heal and toe shift b/c it's what I'm use to doing in my older cars. I'm almost relcutant to use it because I don't want to loose my ability to heal and toe, but I have a feeling that most manual cars in the near future will have this feature since it works so well. It is far more accurate then I could ever be.
