At what point/experience did you feel comfortable disabling PCM for DE's?
Car: 2006 Carrera S
Mods:
Ohlins R&T coilovers
Ferrodo DS2500 pads with Sebro slotted rotors
Hankook Ventus RS-4 - 245/35/19 and 305/30/19, -1.5 front. -2.0 rear alignment
I've completed 12 days of track driving this year splitting my time between Laguna Seca, Thunderhill (ran all configs), and Sonoma Raceway. I almost always run with Sport mode on and PCM enabled. I find the rear can still kick out but saves my ***. I *think* PCM with Sport mode on is less intrusive than other cars, but I want to start working on car control and learning how to handle my car on the edge of grip (increasing slip angle).
Do you find PCM on gives you enough play to allow you to go through corners the way you want to, or am I going to learn to be a better driver if I turn it off and get used to how the car behaves in oversteer?

In my 2007 Cayman S I found PCM very intrusive and in some corners it extremely slowed the car. I always turned it off. It my GT4 I could see it was engaged when no where near the limits but it did not seem as intrusive. I run in the Instructor group.

I never ran it in any car I owned right from day one, but I never had drivers aids on day one.
For yourself it’s when you can catch a car from spinning. You need to understand why you spin out, be able to remove grip from the front tires as a reflex so you can cancel the spin, and have good *** feel for what the car is doing it before it actually happens to know it's about to spin. So if you do stabbing inputs already on the wheel to reduce rear rotation you’re already probably capable of catching a car. IMO at some point you need to not rely on the aids to move forward as they are great at compensating for bad habits.
I never had a problem tracking a 997.2 S and having problems with over rotating it. I found it to be very well balanced bone stock and took well to rotating the *** end around with weight transfer. if your rear end kicks out often I would say you have a driver skill issue, or a car setup incorrectly issue. Too much steering wheel angle when you throttle down is potentially the most common issue with people losing their back ends 'randomly' and aids saving them. Also setting your car up to rotate before you know how to drive is a common problem too. I hate driving newbies highly modified 'race' street cars because they are often setup to correct bad driving habits, like not being able to rotate a car with pedal work and weight transfer.

PCM is porsche communication management. It handles phones and bluetooth.
PSM is porsche stability management.
What in the hell are you guys talking about? PCM or PSM?

In my 18 Cayman GTS I have PSM "sport mode" I run in that all the time on the track . If I had the choice between on and off ... I'd probably go on.
Surprisingly I am running the same pads and tires (not same size) as you and similar experience level .

I never had it in my y2k 911 but for my friend Jason he turned his off in his 2003 911 after about 10 track days because it likely burned up his $2k abs pump. The psm is very basic in these older cars and u doubt is needed.

Interesting,
You talk about all of the "mods" you have made to your car and but not the mods you have made to the driver.
How much experience do you have on how many tracks?
What comments have instructors given you?
What does this comment you made mean to you??

I’m still new to track driving but want to work on improving car control. I’m genuinely asking if I would be more productive to turn off PSM and learn from my driving mistakes. Also wanted to hear how intrusive they found it.
just trying to learn and educate myself!

Imho, u will be faster and become a better driver without the psm. I have seen it. I would think u r at the point know that u could turn it off for a session and judge for yourself.

I commented on my post I have 12 days of track experience….this year and ever. The mods and tires are listed so members know the car is setup with less under steer from stock so it’s arguably easier to go beyond the limits of grip.
