ESC and TC explanation

Damn, that was stupid what I wrote.
I can't believe you can swith ESC off and keep TC on in Porsche. I never paid too much attention to those two buttons as I only switch everything off.
I can bet my hand that it is the other way around in BMWs. I drove 335i and M3 for a while.
Sorry!

It doesn't make any sense to leave ESC ON and TC off, ESC need 4 wheels in traction in order to stabile car, if 2 rear wheels are spinning (power sliding) for the rear brake to slow down the spinning is limited, because engine power is greater than brake force, so ESC must work with TC

There is no advantage or reason to drive with TC off and ESC on. All on or all off except the above situation.
Even if you deactivate TC the ESC will work exactly in the same manner as with the TC ON.
PTV is always on. You cannot deactivate this system.

Doesn't make sense to me. Car can disable ESC, or disable ESC+TC.
ESC off let's the car rotate / spin without intervention, but won't let you spin the rear wheels with excess power. Further disabling TC then let's you excessively break the rear wheels loose (for "drifting", as sn example).

Interesting thread. Depending on the sophistication of the system, you'd ideally want ESC off and TC on.
That way you can still rotate the car on entry as you'd like without having to worry about the ESC catching the car and making it run wide.
With a sophisticated TC system, you can put the power down early and aggressively and the computer will limit the power output as it detects wheel spin in relation to steering angle, yaw etc. You can still overwhelm it and lose control but if you're smooth, it'll help that extra little drive and keep things tidy on corner exits. If the system isn't very sophisticated, you'd be faster with everything off but on a high end system, you'll want to run in the "race" setting that allows for TC without any ESC to produce fastest laps.
ESC will also wear through your brakes a lot faster esp if it's engaging often.

How many race cars do you know have ESC? Non! (Except GT4 Clubsport, because it's a production system)

For the reasons mentioned above, that's why Porsche has this 2 stage system. If you are not comfortable in the car. Leave all systems on. If you want to be fast, turn off ESC and leave TC on.

ESC off and TC on allows unlimited rotation on braking and a lot of rotation on throttle. In fact, it will allow laying rubber stripes and some tire smoke when powering out in 1st-2nd gear, but not a full-on burn-out. With ESC off, TC is noticeably less restrictive as well. For example, all-on mode causes TC intervention when going over rumble strips after T11 on Thunderhill (shen cutting the S) and with TC-only, it never happens.

What you state above-- "you can deactivate TC alone" is NOT possible in the GT3. The ESC can be deactivated alone, or both ESC and TC can be deactivated, but TC alone CANNOT be deactivated.
TT.

Read this entire thread and this is the best point. Race Cars do not have ESC but do have TC.
I have driven with all on, ECS off and ECS+TC Off and all on does intervene but not as much as thought. It is actually a great paramter'd system. But I agree ECS only OFF is perfect.
