997 C4S Sport Chrono Plus retrofit

[Serottab]

Hi all ~

Many great helpful responses to previous questions, so here goes - Looking to pull the trigger on a new 997 C4S with all my desired options, save one. On a one (lightbulb replacement) to ten (engine swap) scale, does anyone (Loren - ?) have insight as to the possibility /pain of installing the Sports Chrono Plus option (sans dash clock) into a new 997? I keep thinking it's "just" a tip switch, some wiring and probably an ECU re-program. This is probably the one option I will use the most (read: Launch Control!!!) and don't understand why it's not included on this model. Current ride iis an '04 C4S w/Tip, a great car, but after driving that new PDK trans I'm sold. Thanks for any help - :renntech:

The only way to have this option retro fitted will be to have the rear DME recoded and configured for it. Certainly Porsche main dealers will not do this for you so you will either need an independant specialist with the PWIS tool or a software tuner to reflash your software. Either option will invalidate any warranty so if you are buying a new car this is something you may want to consider carefully. On the earlier cars 997 gen 1 the sharper throttle response and higher red line could be recoded by getting a softronic reflash. I am not aware if the reduction in PSM intervention was possible with the reflash. Personally I would spec this as an option rather than trying to get it added at a later date or talk to Sportec, Techart, Manthey, Ruf , FVD , about their options on ECU recoding before making a decision.
