I wrote this in anothe post, about the shifting experience for me. The reason I chose not to do the update was because the quicker shifts made the car faster. If you nootice in their literature over the 200, 2003, 2004 model years, the zero to 60 times drop, as well as the quarter mile times. That's due to the shift calibration and added weight to Spyders in '03 to fix the cowl shake. I wanted the fastest Spyder I could get, shift smoothness wasn't a big concern. But like it was mentioned, the '04 shifted noticeably smoother all around. It depends what you are after...
"About the shifting... I drove 2002, 2003, and 2004 Cambio Spyders back to back. All had skyhook, and here's my conclusion:
The 2002 shifted very quickly in sport mode. It had no software update, or clutch update. When at full throttle, the shifts were insanely fast and sharp. However, those same characteristics when driving part throttle made the shift feel rough/jerky. Also, when pulling the car off the dealers somewhat slick epoxy floor, at the slightest throttle the wheels would slip a bit. Imagine a clock mechanism.. slip,roll, slip, roll. On the concrete it rolled smoothly.
With sport mode off, the shifting was slower, noticeably. However, with part throttle driving and a slight lift of the throttle just as you pull the paddle and the shift was pretty smooth. Suprisingly smooth, albeit not perfect. I then tried auto mode for about 30 seconds. It was bad. Jerky, rough. (consider that bad to me is compared with a true automatic). Saw no reason I would ever use this mode. Valet perhaps...
The 2003 had the clutch upgrade but also did not have the shift software upgrade. Same exact shifting as above, couldn't tell a difference in shifting. The only noticeable difference between driving the '02 and '03 was the 'cowl shake'. We have some seriously crappy roads here and the cowl shake was the worst on the 2002, but still there on the 2003 to a much lesser extent.
The 2004 was a different story. It came from the factory with the new shift software upgrade and also the clutch upgrade. First thing I noticed was that the tires rolled smoothly over the slick floor. When driving in sport mode, the shifting was noticeably slower than the '02 and '03. It was also noticeably smoother. When sport mode was off, smoother, slower. In auto mode, smoother, but still rougher than any automatic or well experienced driver with a manual.
All the info I wrote above about updates came from the dealer. They were great. Explained everything to me, let me drive several, and were very patient.
This is just my observation. "
