I just lowered the winter tires setting that I use for my track tires to 1.5Bar, or 21.75PSI on the TPS.
Anyone else done this?

I have not tried it yet, but this should eliminate the flat tire warning as long as I stay above 22PSI cold, while still showing PSI pressures of the tires, typically 3-4 PSI off, but still you can see them increase and if I ever get a flat on the track I will be able to see it coming before the next corner hopefully.

Also disconnected the seat belt warning and took out the option of unlocking doors when you open the trunk.

I have not tried to do this, I thought we just had to disconnect them for the track. how did you do the adjustment? did you need the special equipment or ??

You can set the values individually front and rear, summer and winter tires.
We think the values were Minimums and below that it gives a flat tire warning.

Again, I have not put the track (Winter) tires on, so I can not confirm yet.

You need the Porsche service computer to do this.
