AVM, Thanks for the great information although I am a little confused.
If one has a base boxster and one has SC retrofitted aside from the clock which I totally understand what other features, characteristics or upgrades will one not get since it was added after market
I am not completely certain what you mean by ‘other features?’ Hope the following helps . . .
As per my example above, my first Macan Turbo came only with Sport (engine) performance from factory. What exactly is Sport and Sport Plus when it comes to engine performance? More on this further below but, as far as I can tell, they only offer performance enhancement to those using PDK in automatic mode.
My Macan Turbo also came from factory with PASM (suspension performance) and PSE. PASM comes with three settings (Normal, Sport and Sport-Plus).
In the picture below, I only had the ‘Sport’ and suspension buttons from factory (no Sport Plus performance button). The Sport Plus button was added with retrofitting. Again, the entire left control panel is replaced, not a simple matter of adding a Sport Plus button. Please note that the suspension button has three lighting options if you have PASM. OFF (no light), ON with one light lit (Sport), and ON with two lights lit (Sport Plus). You can control suspension independently by use of the suspension button.
Conversely, if you press the Sport performance button the suspension will automatically also go into Sport mode (one light lit). If you have Sport Plus button and press it, the suspension will automatically go into Sport Plus mode (two lights lit). Of course, you can set options according to your own liking by pressing buttons, as well as through your ‘Individual’ option. Finally, please not that Sport suspension is different than PASM, as the former is set, while the latter is adjustable.
Similar comments regarding exhaust options (e.g
., +/- PSE), which are also linked to performance mode.
Through the above examples, you can see there are multiple different scenarios regarding how retrofitting Sport Chrono can impact engine, suspension and exhaust performance – depending on what stock options you order from factory. Therefore, it is not a simple matter of ‘adding a button’ to the center control panel; why the programming is vehicle specific; and why I recommend having the install done by a certified Porsche dealership.
As far as engine performance goes, Sport Chrono is most apparent with PDK automatic mode, as shift points are altered and typically occur higher in the power band (e.g.,
higher RPMs). I do not wish to digress too far, but this is the basis of a recent thread I started regarding PDK manual mode. Namely, my sense is that shifts are faster, but I have been unable to get confirmation from Porsche literature or forum members – other than some have similar, albeit unconfirmed impression.
If you think about Sport and Sport Plus exclusively in terms of engine performance, the only thing I can confirm is altered shift points in PDK automatic mode. If such is the ONLY engine performance gain, then it would make absolutely no sense to have Sport and Sport Plus (Sport Chrono) with a MT where you control your own shifts. Likewise, if you prefer to drive in PDK manual mode – as I do – then there would similarly be no advantage.
I must believe there are other advantages for which I am unaware and inquired about in separate thread. By ‘advantages’ I mean things YOU cannot control via performance of your own shifts (MT or PDK manual mode), or pushing PASM and PSE buttons. I do not consider ‘more burbles’ in Sport mode an exhaust advantage or improvement, and would certainly never get Sport just to hear them. Likewise, you lose the enhanced burble feature with Sport Plus (Sport Chrono). At this point, I am convinced the only performance advantage with Sport or Sport Plus comes with higher shift points in PDK owners using the automatic mode.
Well, there is one ‘other feature’ for which I am aware when retrofitting Sport Chrono. Namely, gaining access to Launch Control and corresponding to PCM functions (e.g
., lap times, etc
). I never use Launch Control, so not a feature I have ever explored to any significant extent.
