It took me a while, but I finally did figure out how to get a little more fun out of the SC430. If you put the ECT setting into Winter then it will shift to the highest gear that you have selected. Select first gear and turn off Traction Control and the car will drive as if it were a manual transmission. Then when you shift up to second it will automatically perform the shift and stay in second, etc.
I'm sure that you will rarely do this, as I rarely did, but still good to know.
