I had to move my second set into the house as having two sets of transmitters in the same garage was confussing the OBC!! Plus it's much nicer to clean them inside.

The setting for this is done with the same control you reset your odo with. The TPMS settings are there 1 or 2 down from odo.
I had tires put on yesterday and rode home with no low or flat issues in TPMS but when I went to park car got the warning.
I will be looking into this more to see if the required amount 33 - 39 (997S) partial load can be reset lower through the computer at the dealer.
I'll post here if I find anything more on this.

Dealership keeps trying to convince me that the TPMS sensor is more accurate than my Longacre handheld gauge - the differences are in the 4-6# range. The service guy claims the pressure "at the valve" are just wrong. First, pressure doesn't really work that way. Second, to get the system to work consistently, I've got the rears at 40 psi (to get a 33 psi, flat reading on TPMS). Third, I race a 951 and a Miata, and I set the TP using the same gauge. Anyone have thoughts on this? To me, it sounds like they just don't want to fix the TPMS or tell me that it sucks.

That is the first time I have heard that one. can't imagine the logic. How can a valve have that kind of effect unless its blocked, if it was you would have no air pressure at the stem. I would trust my longacre. To many of us find them to be a POS

I too hate the TPS reports
Ever since I purchased some new tires, the porsche gauge that came in the front of our cars reads 29/33 as the door says. A cheap gauge reads 29/33, and my longacre reads 29/33 both sides.... TPMS reads 24/29 on one side, and 26/31 on the other side. I have tried to use the recalibrate option a couple of times and it doesn't seem to do anything useful. Glad to know this is miles ahead of bmw and others :P

why dont you ppl just kill it?
I would like to get it disabled, I think Champion Porsche will do it for me. Won't I get the ! warning light and Low pressure indicater? I suppose the display will just show 4 dashes instead of the pressure?
i really hate it. i can't figure out how to kill it at first, so... i bought three 2006 cayman s, b/c in 2007 they will have TPMS. that's how much i hate tpms.
i have now figured out how to kill tpms.

Found it, thanks Mooty!:
1: First you must actually disconnect the TPMS control unit so that the CAN Controller does not continue to recognize it. The control unit is located in the front trunk next to brake fluid reservoir. Remove and unplug the dome light on the cowling plastic. Remove all of the screws that hold this entire plastic panel in. There are a good number on top by the seal and one on each side by the bottom.
2: Now unplug the control unit it is part number 997 618 103 06, Do not remove it. This way you can always just plug it back it and use it again.
3. Reassemble the front trunk again.
4. Hook up the PIWIS tester to the car via the OBD2 port and do a complete check of all the control units.
5. Select "Gateway" and then "Coding" then ""Required Control Units List". This will list all installed CAN units.
6. Now select "Tire Pressure Monitoring System" and change to " Not Installed" and code it, then exit to the main screen again.
The next steps will code your instrument cluster and to do so will require that you have your engine number, so have it handy, you will find out why.
7. Select "Instrument Cluster" and then "Coding" then "Vehicle Variants".
8. Now select your "Model Year" then "Model", "Roof Version", "Country" (02 is for USA, Puerto Rico). The next item will be "Versions" (553 is USA/Canada).
9. Select your "Individual and exclusive equipment" by highlighting each item that would apply such as: 454-Cruise, 023-Silver Colored Gauge faces etc. DO NOT select 423/483 TPM!!!! This is the TPMS for the cluster and must not be highlighted.
10. Move to the next screen and finish the "Audio and Communication " by highlighting what applies to your car.
11. Next will be the "Wheel Size" and finally it will ask about your engine number.
12. Proceed forward and then Code with F8.
That’s it and now TPMS is removed.
