Yea so I got that part but what I was confused about and can't seem to get a solid answer was about the stability portion of the VDC. It seemed from factory with VDC off all stability was off to the point you could spin a 360 and there would be no stability assist to straighten you out (as was tested doing the VDC off test at leguna "warm up" figure 8 in parking lot. So with ecutek VDC off I know wheel "slippage" is now tunable but what happens with the stability assist portion? With VDC on it will use yaw and steering angle to do selective braking to help keep you straight but what about when off now? I haven't been able to go find an empty lot to go play around it and get a feel for it yet.

Sure thing. When you start the car, it defaults to VDC-on, just like stock. To enable RaceRom:

1. Turn VDC off
2. Adjust the wheel-slip amount using the cruise control accel/decel. When you press up or down, you'll see the current value displayed on the oil temp gauge. It ranges from 0 to 100% (i.e. off to no-wheel slip) depending on what you set it at. I usually start around 50% and adjust from there. You can change it anytime the car is on.

Hey so I got my tune and still adjusting to the quicker throttle but I think I like it, need to give it a couple days before I know. I have asked Seb about the VDC thing a couple time but I am still not completely sure I understand it. Since you have the same thing and go to some of the same tracks I plan to, can I ask you a bit more about it vs Oem?
