Does the traction control remain on now on .2 Carrera's, even with PSM off? My 991 experience has been with a separate TC button which also had to be disabled to fully turn things off, as with the 991 GT3. I did however see the Motortrend video of Randy skidding a base car, similar to mine. He mentions "with everything off".
I only have a PSM button on my car. No TC button below it. Even in wet conditions, it doesn't want to allow any spin. I'm confused. I looked over the manual and searched.

For cars with Sport Chrono package, press the button for at least two seconds. Confirm on MFD that it is switched off. A short press will only engage sport mode PSM rather than off.

I saw that in the manual. This is a non sport chrono car. Very base setup, almost no options.

For a 991.2 without sport chrono, does putting the car in "Sport" mode relax the PSM settings at all? If not, does the PSM ever get too intrusive on the track (for mild DE usage)?

Thanks

Yes. I recall about 4 degrees of slip before PSM engages.

However, PSM is never really off in the 991.2 or .1. It is always awake in the background and if ABS kicks in, so does PSM even if selected off.

The math being performed in the different modes is confusing for sure. Here are my experiences on the track.

With TC engaged (991.1 C2S, running in Sports+): I can get a fair amount of slip, drift, and rotation. Probably less than 10 degrees, enough to feel (and accomplish the job if you're intention is a little rotation) but not enough to over react and big counter steer.

With TC disengaged (same car, same track, same tires, etc, in Sports+): I can get way out of sorts, counter steer is required, and it appears there is NO intervention at all ('appears' would be the operative word because I suspect some/slight things are going on in the background). Example, an abrupt throttle lift at turn in will result in a 360, with TC engaged this doesn't happen.

The tell-tell sign is that with TC engaged my car will chew through rear pads faster than fronts. With TC disengaged I get 3 fronts per 1 set of rears - as it should be. More importantly, the with TC disengaged the car responds and feels like you expect it do - MUCH more natural.

The ultimate question: Am I faster with the nannies off? Yes and no. Turning off TC allowed me to take the car to another level, it was awesome - but I loose Throttle Blip (bummer because I got used to it and like it, one less thing to worry about). I then ran a few track days with TC engaged and discovered something, similar feel, similar times, and similar rear brake pad wear - plus I get Throttle Blip.

Moral of the story, I think I had to learn to drive the car with TC off and am now a much better driver with TC on. Do I track the car now with TC on or off? Depends on the track and conditions; wet track, TC is on; tight walls (as in no runoff) TC might be engaged (depends on the session); open track and dry, TC is off.

For reference, I bought this car 1 1/2 years ago and have 78 track days on her.

^very good post above by Jabs1542!

So basically there is no way to turn off traction control on a base 991.2? That's insane if that is the case. What is this, an Audi...

What I can't understand is how Randy skidded the car around the track in the motortrend video of the red base 991.2 C2?

You can't induce full oversteer to the point of spinning the car on any 991, outside of the GT3? I can't recall how the 50th was.

With PSM off, you can drift as much as you wish and do donuts.
I believe the TC only kicks back on when you panic brake and put the car in ABS.
We drift, slide and spin the car all day long at the LA Experience Center without the TC intervening.

Thank you for the feedback. Is this on 991.2's?
I was out in the rain yesterday (with PSM off), giving it full boost in sharp angle turns, as well as from stopped positions. Could not get the tires to spin at all. It was quite bizarre.

mcipseric

Yes, we only have 991.2 at PECLA.
Not sure why you could not break the car loose.
If you can, schedule a session at the Atlanta or LA Experience center. You will really enjoy it and learn a lot!

Ceepe

Gotcha. Thanks again for the feedback. I would enjoy playing around at an experience center sometime, yes. On the local level, I will get the car out at Lime Rock a couple times before the end of summer hopefully.

i live in Toronto and would like to visit to help hold me over until my GTS 4 Cab is delivered. I have seen your individual car and 2 car items. Is there multi car full day option. For flying accorss to LA I would really like to make a day of it to justify the flight and stay.

thanks

Something to consider. I had a 996 I could throw around like a rag doll. Replaced that car with the 991 and was utterly frustrated at first, then I learned something important. The 991 is wider, longer, better planted, better suspension, etc. What it took was I had to slap the car harder, much harder. In fact, you really don't know how amazing the car is until you take it past the edge - and it really takes a lot of effort to get there. An open parking lot after a rain should get you there
