How does PASM actually work

[le_gazman]

I’ve had my 991 Carrera S for a while now and think it’s actually more comfortable with PASM in Sport mode, but can’t really pinpoint why. It seems to stop it rebounding so much, so feels a bit tighter but that’s about it. It just feels better but not sure why.

That’s really interesting, thanks. It does feel artificial and frankly loose or even knackered in Normal. It doesn’t feel properly connected till you go to sport.

Not sure what Sport Plus chassis does beyond Sport - just harder damping still?

I'd be interested in this - sport mode does different things on different 911s.... from memory...

On my 997 it sharpens throttle response, allows more slip before kicking in PSM and turns on PSE

In the 997 Turbo sport mode gave you something like 20 seconds of overboost probably enough to get you close to 200 MPH, so without that you couldn't get the full power of the engine. Remap cheaper & can use the power all the time

In other cars sport plus does things like holds gears even longer into redline on PDK and maybe gives an even more aggressive throttle map. I seem to remember from the 997.2 onwards Sport Plus was only really worth it with PDK

I meant just chassis in sport plus mode, but yeah the car becomes a bit of an animal when I hit the sport plus button. Definitely holds you in gears longer in auto and even forces downshifts when braking. Throttle response even from normal to sport is night and day. In anything other than urban traffic I have it in sport mode with sport chassis and the exhaust on. Feels like a much tighter package then.
