Sport and sport plus effects on traction control
Discussion
Hi all, I'm fairly new to the Porsche fold and have a PDK Boxster Spyder with Sport Chrono Plus so have Sport and Sport Plus buttons but no PASM.
I know the effects that both Sport and Plus have on throttle mapping, holding gears, shift speed and launch but what I can't find any info on is the difference in allowing more wheelspin and slip angle.
I believe there is a difference between normal and Sport ( not sure what it is) but is there further effect in Sport Plus?
My experience is with M BMW's where you get TC on which is quite intrusive, MDynamic Mode which let's you get the back out but catches you if you go too far and TC off.
Thanks for any info!

Gawd Demon you are a fusspot sometimes.
From the manual:
"Sport Plus" mode
A sportier setup is obtained when "Sport Plus" mode is switched on.
PSM interventions occur later than in Normal mode. The vehicle can be maneuvered with greater agility at its performance limits, without having to dispense with the assistance of PSM in emergency situations. This helps to achieve optimal lap times, particularly on race circuits and on a dry road surface.
How this pans out is also different across the range. I believe that on some of the models, PSM will only kick in if either one of the wheels locks in "sport" and will kick in only when both wheels lock at the same time in "sport plus".

You probably right although, the manual is not prescriptive enough imo.
Looks like you can set the PSM into standby mode with Sports Plus on, I don't know if you can in Sport. You ever tried it? I have only tried it in Sports plus mode for the launch control. You have to switch the PSM off to use LC.

Not that it is entirely relevant as it is a new and different model but on the 991 Turbo, reading the documentation, the PSM threshold is only raised in Sport Plus and not Sport.
'As standard, the 911 Turbo models are equipped with enhanced Porsche Stability Management (PSM) which maintains stability even at the limits of dynamic driving performance. Sensors continuously monitor the direction, speed, yaw velocity and lateral acceleration of the car. Using this information, PSM is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels to restore stability.
Under acceleration on wet or low-grip road surfaces, PSM improves traction using the automatic brake differential (ABD) and anti-slip regulation (ASR). When the SPORT PLUS mode of the Sport Chrono Package is selected, the PSM threshold is raised to allow a sportier driving style.'
flicked through a couple of the manuals.
in typical porsche fashion its' clear as mud, just like over-boost on the Turbo S.
looks that the answer is still 'yes', Sport Plus does slacken the PSM further over sport mode but you have to have the PSM button set to 'off' or 'standby' as Porsche put it in the manual. With PSM in standby mode Sport Plus is even more slack than Sport mode as it will wait longer to re-engage PSM if you start locking front wheels.
There, I hope that is the right answer.

Thanks for the info. I've looked through my manual and mine is different, the only reference to PSM in Sports is "PSM interventions take place later than normal...." and there is no reference to PSM in relation to Sports Plus. This is something that may be model specific I guess or possibly a difference between 2 and 4 wheel drive?in typical porsche fashion its' clear as mud, just like over-boost on the Turbo S.
