I finally was able to wire up the Parking Dynamics Electromagnetic Parking sensor system and test it. As I noted in another post, the metal foil antenna for the Parking Dynamics system is on the backside of the nose cone. It has a sticky back, so you just tape it in place. I covered it with two layers of matte medium for extra protection. I set it up for extra sensitivity and range by running two parallel lines, and a few connecting lines between the two parallel ones (recommended by Parking Dynamics). I also set the ECU for maximum sensitivity. No holes in the nose cone or bumper are necessary for this system. See this post for photos of the foil antenna on the backside of the nose cone and the control box for the cubby. Tonight I wired up the nose cone to the Parking Dynamics ICU and switched it on. My dog was hanging around and the minute she got within about a 18" of the nose cone, the system set off an audible warning, beeping faster as the dog got closer, and changing to a steady tone as she approached within about 6 inches. I did some other tests with my hands, various metal rods I have around, and even a 2X4. The range is about 18" and it extends out at an angle of about 60 degrees or so from the edges of the nose cone. I'm convinced on the basis of this test that the system will make an easy-to-install (DYI for someone with minimal technical skill) parking warning system that will be highly effective for front end protection. And I love the idea that no holes in the bumper will be necessary. I know there have been skeptics about this system but on the basis of this test I don't think the skepticism is justified. When my Model S is delivered around the end of April I'll be able to do some real world test as well. But for now this system is a go!
