Default Disabling 'drive-off assistant'?

Does anyone know how to disable Porsche's 'Drive-off assistant'?

This is on a Cayman R, but it sounds like all 2009+ cars get this "feature".

Thanks!

Is this the park assist feature where the brake holds (for what seems like an eternity) when you leave a stop/hill? If so, I never found a way to disable it and detested it in my CS.

Yes. An amazingly bad implementation on the manual cars. How could this 'feature' not be disableable?

I've got several people looking for a way to kill it. When I find it, I'll let you know.

My 135 has this, and the brake releases as soon as the driver presses the accelerator pedal.

The only manual-trans Porsche I've driven newer than MY09 is a CR, and it had this same defeat mechanism I believe.

I bet PAG decided to put that on the 997.2 as they needed practice... as it is now essential on the 991 (electric/pushbutton e-brake).

If it was set up to disengage as soon as the clutch comes off the floor stop, it would have been fine. The way it works on my car - If you release the clutch before the ~ 1 1/2 seconds, then you feel the brakes drag until you add throttle to generate enough torque(?) to disengage it, or the time expires... pretty weird when you only want to pull into the garage from the driveway (where it only seems to engage about half the time).

Does the GT3 and RS cars have this? I never really noticed.

If it worked that way, it would defeat the purpose of the hill-start assist; the clutch doesn't immediately engage as soon as it comes off the floor stop. On BMWs, this "assist" only happens when the car is facing uphill.

So do a throttle blip before the clutch reaches the friction point. This should disengage the hold mechanism, right?

Well there are four tables when translated and interpolated, plus a possible two further that are associated with it. I'm pretty confident that Todd/EVOMSit can 'nuke' it but I need a car here to test it on or in AZ before we do any guesswork
