Trust me, the floor was the only thing keeping the pedal off the pavement.
I have performed this type of start over 100 times and this is the only instance where something like this has happened. I don't know whether the
PSM was the culprit or not. It felt the same way as the
PSM intervening to limit the throttle when the *** end of the car is about ready to break free. Since I have a tiptronic I don't know what it feels like to hit the rev limiter in this car but this felt similar to the rev limiter I have bounced off of in other cars I have owned.
I was only offering this as some insight as to what might be going on electronically with two different controllers trying to limit the same activity in the vehicle. I think the first thing to solve would be to delay the upshift past the redline. Then you could start working on the more traditional rev limiter. My experience may show that it is possible to delay the shift so that the rev limiter can be hit. Has this happened to anyone else?

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
