If you purchase this from Softronic you get the cable to install the software yourself, when you need to take in for service you reinstall the stock software with the same cable and no one will be the wiser.

 

...deleting a "clutch delay switch"

OK, so I followed the instructions in the link/thread provided and tried it out tonight. All I can say is WOW!! The car (at take off) has been transformed. It can now pull itself forward without any throttle when you release the clutch (smoothly). And it feels like I have some reasonable power at idle. The car gets off the line much, much easier ... and much more in line with my original expectations.

Even when moving - the gear changes now are as smooth, or as rough as the driver (ie. me) makes them ... so much more enjoyable to drive now. And it's not like I was not enjoying the car before, but now it's a much better / unfiltered experience.

I'll have to put the G'tech on the car now and see what difference this makes to off-idle launches.

ps. Thanks so much for pointing me in this direction.

 

I had the exact same experience. As a bonus this 'mod' is easily reversible. I'm glad you found the thread informative.

 

OK, put a G'tech on the Boxster and with the clutch delay switch disabled I shaved almost 1/2sec of the 0-100kph and 400m times. ie.

-0-60mph = 4.96sec
-0-100kph = 5.21sec
-400m = 13.31sec @ 170kph

Car seems to have a lot more power then you let the clutch out now.

ps. all times with 1" roll-out.
