In regard to the snow... I started writing that comment before you responded... so I only saw your response after my post. Obviously 6 inches of snow is going to be more than the 4cm I saw from a quick google of your location. My point was NOT to be condescending, but to say that the DSC system quirks really need to be experienced to be understood.Firstly, you don’t need any snow at all to understand how the VSC works, you only need a low friction surface and we get plenty of ice in winter. The next is your failure to consider that not everybody is a “regular Joe” when it comes to VSC and the associated systems and I was involved in vehicle testing and dynamics for 17 years. I’ve been on every testing ground in Europe and you cannot test brakes without testing ABS, TRC and VSC. I’m sure i’ve forgotten more than most people know on these subjects.
If you want to talk about condescending, here is an example: "I’m sure i’ve forgotten more than most people know on these subjects." Nobody cares. Seriously. Who cares how long you worked on these systems? Did you work on this one? When we order machines for our lab, they are supposed to work under certain parameters. If they do not, that machine is worthless to us. The engineers will look at the data logs and think everything is kosher until we get them in for a field visit and they see the actual problem. This was why I was asking about whether you yourself have experienced the power cut induced by DSC. Sure you don't need only deep snow to experience this, but in very snowy conditions the problem is worse.
I can tell you that the system works decently in a straight line. It will allow much more slip before cutting power (so it seems) if your steering wheel is straight. However, it seems the threshold is much lower when the wheel is turned. Once DSC cuts power on you mid corner maybe you will better understand what I am talking about. Then we could use your experience to determine how the system could be programmed to better respond to driver input and the environment.
