I didn't experience any tire spin, so I doubt turning
PSM off would have changed anything. Using
SC might have made a tiny difference, only because I am not used to the hair trigger throttle response and it probably would have made my shifts harder. I agree on the A/C.
They are very accurate. I remember reading an article in either Car & Driver or Road & Track, can't remember which, and they found the
Escort to be within a very tight margin of the uber $12,000 meter that they use. I can't remember the specifics, but I will do some searching and see if I can find the details. The biggest limitation to the accuracy will really be the surface. For example, if I launched my car down a hill, I would obviously get a very fast 0-60 time. Up a hill, it's going to be slower.

Maybe someday, on the 45+ hp I mean.

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. |
