Just noticed that Porsche has (finally!) come out with a software update and console switches to upgrade non-Sport Chrono cars with the Sport / Sport plus (launch control!) performance aspects, sans the timer on the dash; see link below. Hallelujah, finally the best of both worlds IMHO. Wondering if it could be a DIY install - Aside from the mechanical installation of the switches, does anyone (Loren) know if the stated "enabling code" from Porsche would require PIWIS validation, or just selection via dashboard menu? Does the enabling code imply that all the cars come with the ECU code pre-installed from the factory, just waiting for activation?

Wow that's really cool... And the price is not bad either....

My 4S came with it and I now having it I can't imagine having one without. The gearing and accelerator sensitivity changes make a huge difference for how the car drives (likewise the PASM changes, but I don't think that's part of this particular package).

Normal mode = nice comfortable commute. Sport = Wrroooom spirited fun. Sport Plus is just overdoing it outside a closed track.

I recently installed the sport option in my 09 Carrera S six speed. From the brief time I've driven the car post install it does seem to have better throttle response. My primary reason for the update was the benefit of the changes in PSM and ABS. I won't know about that util Spring.

With the 20% off coupon I think I paid about$ 825.

What they do is play with the electronic possibilities of the E-gas system, on a normal 997 (non sport) the throttle valve move simultaneously with the accelerator pedal, 25% pedal movement = 25% throttle valve opening, 50% pedal movement = 50% throttle valve opening, etc. till full throttle.

On a 997 with sport option runs the throttle valve faster than the accelerator pedal, 25% pedal movement = 35% throttle valve opening, 50% pedal movement = 75% throttle valve opening, etc. till full throttle. Both versions are equally fast at full load, only at partial load (till approx. 80% pedal movement) there is a noticeable difference by the modified program.
