So does anyone know how to get this transmission to launch? It shifts fast but that initial takeoff seems slower than it needs to be.
It is my perception that if you drive it like a viscous-coupled automatic it behaves like a viscous-coupled automatic. Or, in other words, if you habitually leave it ‘in gear’ at stop lights you get the ‘windup delay’ that people expect of automatics.
I always paddle-shift to neutral when I stop. When it’s time to go, I click a paddle, instantly take my foot of the brake and mash the go pedal. At some point after the paddle click I can feel/hear an engagement from the PDK that tells me it’s time to mash ‘right now.’ And when I do, there’s no hesitation or windup. If you don’t mash, once you get the engagement the car will creap.
On the other hand, if I stop and keep it ‘in gear,’ when it’s time to go and I move the foot from brake to throttle I perceive that there is viscous-coupling-like ‘wind up’ before movement after mashing the go-pedal.
Obviously if the above is real and not my warped perception then it’s all about the software. And this is based upon my 991 Turbo that may have different software.
Also, I do believe that the PDK is adaptive. So, an abrupt change of driving habit may have no effect for a while. There is a procedure for ‘clearing’ the PDK. I won’t try to quote the procedure in this post (it’s googleable.) You definitely should do that before you try a big change.
On the other hand, a lot of PDK 991/981 folks complain about a ‘hesitation.’ I’ve never known if it was a ‘real thing’ or not, or related to PDK adaptation and ‘viscous-coupling-style’ driving. Some folks say that they have experienced it on some 9s and not others.
