First, a disclaimer : I don't develop, work, advertise, sell anything here. I am just, like most of us, a curious normal user of the car.
There have been very nice discussions recently on the technical limitations of the car (https://www.taycanforum.com/forum/threads/part-1-mapev-diag.25758/ - see part-2 and part-3), and what can be done and cannot be done (or expected). In short, you can't do much. But some users with a tuned car have however felt quite a difference between the stock and tuned units. Why then...
I'll start with the Launch Control procedure: it's not just an overboost for a few seconds as claimed by Porsche, it's a different power curve used until you realease the accelerator. You get the max. power from 0 to Vmax, ie during something like 15 to 20 sec. If you just release the pedal, and reaccelerate again, you'll go down to the standard power curve even if you are in Sport Plus mode.
You already understand what can be easily done: activate the LC power curve whatever the mode, and whatever the speed (I mean you don't need to stop to activate it). It'll give you the full power the car is designed for without, somehow, putting at risk some parts/components of the car.
This has a side effect: you shouldn't see a difference in any 0-xx mph test results. But the car will feel very different when rolling and accelerating because of the different power curves.
So, is it worth doing it ? My personal views:
- the price ? I was curious, so it's the price to satisfy my curiosity
- the use ? I have never done LC before these tests in two and a half years. I leave downtown, I won't drive at these speeds there. But I do a lot of highways/national roads trips, and I really do feel the difference. I forgot to mention the increased top speed: it's usable only in Germany. I would never go these speeds elsewhere in Europe (I had an unpleasant situation in France some time ago ...)
- the reduced reliability ? One could assume that since the tuning consists only in activating a power curve designed by Porsche, it shouldn't have any effect. Someone with a stock car doing 1 LC every morning will put more stress to the car
After all this bla bla, a few curves and results now ...
I've posted some results there with the stock unit (https://www.taycanforum.com/forum/t...-impressions-long-and-nerdy.25001/post-384718) and I won't come back on those.
1/ torque vs speed for different modes:
The 2 curves are almost identical. Almost because SP+ still has this small overboost in torque in the very beginning: we are talking of +6% for 2.5 sec. Does it have a noticeable effect on the results? no. It would matter in Formula One, not here.
From a rolling start (100km/h), the 2 curves are also almost identical. Almost because in Normal mode the car was in 2nd gear, while it was in 1st gear for SP+ But after SP+ shifts to 2nd gear, they are identical. I also include the power curves : higher torque in 2nd gear (Normal) but lower power too (lower RPM).
It was discussed if it makes sense to shift a bit later, ie 130km/h instead of 120km/h. It won't change much : at a certain point you'll have anyway this drop in torque/power when shifting.
In term of power, the curves (perhaps the most interesting ones) below illustrate the difference in power in real life where you (almost) never use Launch Control. You will never feel a difference below 70km/h.
2/ 0 - xx km/h:
These runs were made different on different days, different weather, almost similar SoC (but not identical) so the values are not to be taken as the best one can obtain.
As said above, stock SP+ LC , tuned SP+ LC and tuned Normal curves are identical. It has to be when you had a look at the curves above. Carscanner might not be the best professional tool when it comes to torque/rpm, but speed and time do not lie.
3/ 100 - xx km/h: rolling start
To end on a positive note (...) that's where you really feel the difference between stock and tuned. Again, don't take these values as the best you could get: you might gain some 1/10 s depending of the weather (wind), flat road and other parameters.
There is a difference and you feel it !
