As I tried (rather unsuccessfully) to point out in a previous post, the accel, clutches, and brakes are simply operating normally.

1) With your foot firmly on the brake pedal, the brakes are applied and the clutches are disengaged. (this is NORMAL operation)

2) When you release your foot from the brake pedal and *any* gear is selected, the car will start to move as one of the clutches engage. (this is NORMAL operation)

So far, we have established that the brakes and clutches are operating as they would in normal everyday driving.
...but what about the throttle?

3) When you press the accel pedal to the floor and no load is applied to the engine, the electronic throttle will limit the RPMs to ~3500 (I'm not certain if the RPM depends on engine type or PCM calibration). It *does not matter* if the transmission is in P, R, N, D, S, or L. (this is NORMAL operation)
Except for the fact that when you put it into S, turn off TC, brake + throttle it holds at 2700rpm.

Your 3500rpm is just the natural rev limiter ALL cars have but when you do that same procedure on the Focus it holds at 2700rpm.

Aka launch sweet spot.

If it held at 3500 as simply a rev protector it would make for useless launches.
