I wish there was some tuning capability to it. I was really having a hard time at the drag strip. Since the 35i does not fully disable both traction systems I was not able to use it very effectively, fastest time I ran was 13 flat with a 2.6 60' at 111.0. Got home and I finally figured a DIY way to launch the car. Kinda tricky and takes a lots of practice. If you press the traction once, and hold it to turn off DSC, then put the car in M1 mode by putting shifter to the left, I was able to fully press the accelerator till it hit the button at the bottom of the pedal, then the revs would increase without engaging the transmission, its a very small opportunity but if you tap the brake while pumping the accelerator about twice to hold it at about 3000 rpm for about 1 or 2 secs then launch. Was working pretty well at a empty lot I was practicing. Def going back to the strip aiming for low to mid 12s where the car should be.
