Rain + PCCB = Trouble + TC = Big Trouble
Does any one know how to turn TC off completely and stop this from happening? Or even better, a good safe way to heat up the rotors very quickly in normal street driving?

This happens with sport on or off and with PSM on or off. I tried all four combinations of sport and PSM and none turned this very annoying TC feature off.

In order to be able to activate throttle and brake simultaneously you will have to do it in reverse order.
I.e. if you are on the throttle and you then hit the brake, the car will interpret that you want to suddently stop and will kill the throttle for safety reasons.
However, if you are on the brakes and you then apply the throttle, the car will interpret you are just matching revs with heel-toe and will NOT kill the throttle, otherwise you would not be able to heel-toe at all in the 996/997.
So you will have to pay attention to the order by with each pedal is activated, you have to press the brake and then afterwards apply the throttle.

I'm with Chris on this one. My ex-997S had PCCB and I had a few scary moment in rains and after car washes. It didn't happen often, but it gave me an insecure feeling when driving in the wet.

Never had that happen on steels. Had my brake fluid boiling one time at limerock, that was about it. But I got 7,999 other reasons for not getting them....

Normally heel-toe is accomplished with the clutch pedal depressed. With the clutch not engaged, you don't have to be concerned about applying "throttle first" or "brake first".

FWIW, unlike the brake and throttle systems there is no switch or sensor on the clutch or clutch hydraulics to "tell" the ECU whether the clutch is depressed or not.
In other words, clutch actuation has no influence on the "control strategy" which Carlos was describing.

On the 987/997 I hear a clicking noise at the end of the clutch pedal's travel. What's the reason for that?
