I don't think it's possible to start, stop and reset without taking you eye off the road atleast once; not something I'd want to do at a DE.

The best way I could think of it working is that while at a DE, keep it in the sport chrono mode display before you get on the track then after a few laps and you've got it set to go, press the stalk to start and then at the end of the lap press it again to stop. You'll have one lap time for review but I can't imagine resetting it while driving; so one timed lap per run session?

Anyway, since I've been driving with it on the street I like the more agressive throttle setting and the PSM supposedly intervines later in the sport mode so you can get the rear to rotate more easily. Should be very helpful on a auto-x; the timer without the PCM , however, seems a lot more difficault to use. while driving.
