I understand that the speedometer might not indicate the true actual speed of the car, but the original statement was that the spoiler does not deploy at the indicated speed of 75 mph. I would think that if the cars computer is programmed to raise the spoiler at 75 mph, then it goes up when the indicated speed is 75 mph, whether that is the actual speed of the car or not.
The sensors and systems in the car compute the actual speed. When that hits 75mph, it signals the spoiler to deploy.
That 75mph signal is also sent to the speedometer displays and there it is 'adjusted' to display 77, for example. its just a difference between the measured value and what is displayed. The spoiler is driven by the actual measured value, not the displayed value, which is for human eyeball consumption only.
You can FEEL it. the rear of the car actually gets pushed down by the downward force of the spoiler. It is subtle, but any real porsche enthusiast can feel when that spoiler deploys.
Yeah right. I can never "feel" if the spoiler is up no matter how fast I drive. I guess I'm not a real Porsche enthusiast. Ridiculous
I can see the top of my techart when it's deployed Can't feel any difference...nothing when you're under triple digits anyway. I just like that it's designed to work with the stock wing both when down and when up.
This should help, shot this last month. I never knew when it deployed, if at all, now we have proof!
Unfortunately no speed is indicated but if the local constabulary asks I never exceeded 45mph. It can be deployed manually remember
Of course you didn't. After all, that minivan almost caught you!
