Re: Sports Chrono vs. Sports Chrono Plus?
I have a 2009 CS with 6sp and Sport Chrono--no plus, no PCM. Let me tell you, as a timing device, without PCM the Sport Chrono is worthless. There is no memory without PCM, so when you leave the track you cannot scroll back through you lap times. Also, the cute tracking system where the PCM graphically displays your current lap against a previous lap is also missing without the PCM.
Now, I like sport mode for the revised throttle map and revised stability adjustment--but as a timing device, it is worthless, and there are some great data acq devices for much less than SC with PCM, and they supply much more data.
The revised throttle map of sport mode makes heel-and-toe downshifts much easier for me. Not a consideration for PDK cars.
