The rear spoiler moves up when going faster than 75 miles, it moves down again when going slower than 50 miles.

When going over 75 it will move up and stay up even if you keep your speed at around e.g. 60 miles from then on.

Now after driving my GTS Cabriolet for 1 1/2 years i randomly discovered: If you press the button twice, the spoiler will move down even if you drive more than 50 miles but less than 75.

This is useful when someone os following too close to do a "real" Brake check. Flash the rear fog light and they think it's a brake like with one of the sides just out.

Much safer and adds pucker factor for people being too aggressive.

(If you're in the left lane; please don't do this. Just move over.)

I was reading over some Cobb Tuning literature and stumbled on two discoveries (for me) that a search shows have only been minimally mentioned in any thread I see. This observations apply to both the 991 and 981 engines:

1. These engines are MAF-less, something most often seen previously in the tuner community. They do not have a MAF, they use calculated air flow based upon the MAP sensor (manifold air pressure), the ambient temperature, barometric pressure, engine displacement, possibly others? At least there is no need to think about cleaning the MAF on these.
2. During warm-up when the car is trying to heat up the cats faster, the engine enters "dual injection" mode where the injectors fire during both the intake and the compression stroke. I wonder if the 997.2s did this too since the warm-up growl seemed even more pronounced on those?

Every Porsche that I've ever owned had that feature. I find it quite useful. Fog is quite common where I live, and fog on I-70 in the mountains can be scary.
