It doesn't increase performance!! It just adjusts throttle response and gives a more aggressive engine map, that's all.
Not quite true, I'm afraid.
This all-new integrated system provides simultaneous enhancement for engine, chassis and optional Tiptronic S transmission. The results are even greater performance and pleasure from your Porsche, both on and off the racetrack.
Key system components include digital and analogue timers, a 'Sport' select button on the centre console, a performance display and a personal memory in PCM.
When 'Sport' mode is selected, the engine management system applies a new set of variables to enhance the engine response. A modified throttle map relates the pedal angle in the footwell to a much wider angle of opening in the throttle. As a result, the engine has a much more positive reaction to every pedal input. In the higher gears, a hard rev-limiter provides added protection for the engine under acceleration.
While all this is happening, the PASM system (standard on 911 Carrera S, optional on 911 Carrera) is also switching to 'Sport' mode. The dampers become firmer, enabling faster turn-in on corners as well as better road-holding and traction.
On vehicles with Tiptronic S, the automatic gearshifts become faster and more dynamic. Lift off from the throttle - even at high revs - and the system immediately shifts down to apply engine braking. There are also no unwanted upshifts in manual mode when approaching the engine rev limit. Since the driver has full control over every upshift, the handling of the car is much more secure, particularly when braking for a corner. To minimise assistance from PSM, the trigger threshold for this system is raised. The result is a more natural and involving response to lateral and longitudinal g-forces.
Mid-corner agility is considerably enhanced, with greater scope for oversteer on turn-in and exit. This added freedom of movement is particularly apparent in lower-speed sequences and bends.
For maximum dexterity, PSM can be partially disabled while the car is still in 'Sport' mode. PSM simply monitors the forces acting on the car and will only intervene in the most critical of situations, e.g., when ABS assistance is required on both front brakes.To help you quantify the car's performance, the Sport Chrono Package Plus includes a time recorder unit on the dashboard. Functions are accessed via the control stalk for the on-board computer. Analogue dials measure hours, minutes and seconds, while a separate digital field displays whole seconds, tenths and one hundredths. The digital field runs in parallel with a second display which is conveniently located in the instrument cluster.
Individual lap times can be viewed, stored and analysed using the performance display in the Porsche Communication Management terminal. Available information includes the time and distance travelled on the current lap as well as the number of laps completed and the respective times. The system can also display the current fastest lap as well as the remaining range till empty. Driving times can be recorded for any stretch of road, and benchmark times can be defined. Other useful features include a memory function controlled via the PCM terminal which can store a range of personal preferences, e.g., daytime driving lights, 'Welcome Home' light function, automatic air conditioning and door-lock mode.
It is funny: people spend thousands for Aerokits, leather stuff, wings, spacers, etc. but they don't want to spend a couple of hundreds for one of the most useful features available for the 987 and 997. Strange.
And whoever says he can't really feel a difference, should really reconsider buying a Porsche. Because there is a difference and it is not only about throttle response but also about PSM mapping. For people who intend to use their car on the track too, a MUST. Because the only other option would be to turn PSM off completely and I'd say that 90% of the drivers might have some weird surprises, especially in the mid engined 987.
