  1. Yes, custom for every car. The schematics always show a fully configured car - which very few are. Porsche simple does not put in wires for options that were not ordered (i.e. PSE, Xenon, etc.). Probably save them a few dollars in costs - but costs them in the retrofit market. <{POST_SNAPBACK}> Loren, thanks for the response, even if it is bad news. Another reason to avoid first year of a new model, I guess.
  2. Loren, thanks for the effort. I was afraid it would be too difficult to be readily retrofitted. It does look like a very nice addition. I guess I will keep my tried and true hand-held digital pressure gauge. <{POST_SNAPBACK}> Loren, does Porsche make a specific-to-order wire harness for each car it builds? I wonder if the wiring for TPMS is actually present in the car, but lacks the RDK contol module and the four tire sensor antennae and wheel transmitters & sensors. From looking at the 997/997S wiring diagrams there are only two wires that connect from the RDK control module to the Instrument Cluster that are CAN network connections - They are CAN Komfort High and CAN Komfort Low.
  3. Loren, thanks for the effort. I was afraid it would be too difficult to be readily retrofitted. It does look like a very nice addition. I guess I will keep my tried and true hand-held digital pressure gauge.
  4. Loren, do you know if the Porsche TPMS is available as a retrofit on a 997S? It was not available when I ordered my car last year. The sensor/transmitters can easily be installed in existing wheels.
  5. If you have Sport Chrono, this switch provides the input to the DME. No other switch is required. The additional button or switch is required only for cars withOUT Sport Chrono. PSE is a great addition to the driving experience.
  6. I suggest that you call PCNA customer service and speak to a technical person. Also get your dealer to involve the regional Porsche technical person. If the problem is reproducible, they should be able to determine the cause and correct it.
  7. How about one or more warped rotors? This condition would likely be felt every time down the hill or even on the flat. What happens if you are in neutral coming down the hill?
  8. Any oil, grease or any other slippery substance been sprayed on the wheels & rotors?
  9. Here are some photos of my installation. The last photo shows the Ignition Sense Wire connection.
  10. I just installed the Parrot CK3100 Advanced Bluetooth Hands-Free Kit in my 997S. I replaced the Motorola IHF1000 I had previously installed. The Motorola kit came with a small external speaker, thus leaving the Bose system untouched. The Parrot CK3100 is much better than the Motorola IHF1000. It has a small LCD display that shows (on certain phones) cell phone signal strength and the number for incoming calls. My phone is a Motorola V600 (T-Mobile). The Parrot automatically synchronized my cell phone Phonebook with itself. It is capable of voice dialing and a few other voice commands. I used the Motorola external speaker, although I was assured by the distributor, nicestuffonline.com, that I can splice into the wires for the door speakers without any problem. You can check out expansys.com. They have this device for about $190 plus shipping and has them in stock. I placed the mic between the visor and the trim over the driver's door. The LCD display I placed on a Lexan bracket that is stuck to the side of the dash trim piece just to the right of the steering wheel. I can see the display just below the right steering wheel spoke. The Parrot control box is stuck to the back of the glove box. You have to love 3M's heavy-duty double-sided tape. A mute input to the back of the PCM mutes the radio when a call is placed or received.
  11. Congratulations! It really does add to the enjoyment of the car. Driving is even more fun than ever. This is especially true through the otherwise quiet zone of 30 - 50 MPH.
  12. On the 997 the PSE is controlled by the DME. Personally, I would not want to snip anything in there. I know of no way to allow for separate operation of the PSE either full-time OFF or full-time ON separate from the Sport Chrono and its designed OFF between 30 to 50 MPH. Removing the vacuum line at the change-over valve does provide full-time PSE ON. Restoring this vacuum line to the change-over valve returns you to the Sport Chrono operation of the PSE. I think the legal requirement for Europe is the driving force behind the imposed quiet period from 30 - 50 MPH. Porsche does not want to be in the position of providing a means to subvert this legal requirement.
