OK, I know I don't belong here (I'm just a 996 C2 peasant).... I get Tire Pressure Monitoring System, but what's PWIS/PIWIS???

Is it possible to simply set it up with LOWER initial pressures as opposed to turning it off completely? At the track I was starting with 26F/27R pressures to get the Corsas up to 34PSI hot. If you could somehow tell the system that you are on summer tires with the set points at 26/27, then you'd have the benefit of the TPMS to alert you to a leak and not have it going crazy at the track. Wouldn't that work better than shutting it off completely?
I know the system is not very accurate (well, I suppose every single tire pressure gauge I've used is wrong and TPMS is correct....ha!), but it's a good failsafe system for tire failure.

you can only set summer/winter tires, the rest is auto calculated by the computer.
if you use the car occasinoally on track, no need to fiddle with it.
if you track a lot, i am sure you chk tire pressure very very often, so why bother with tpms ?

only 3 run groups, so lots of track time.
oh sorry forgot you are a wimp, you quite after 4 sessions hahahaha.
SP has at least 4 group if not more.

step by step
Remove cowl trim, disconnect TPMS control unit (on driver side, next to master cylinder)
Go into Gateway control unit, remove TPM from control unit list
Go into Inst Cluster
> vehicle variants
> US/Puerto Rico > select options as equipped (ie silver face gauges, cruise control, etc) EXCEPT tpm
> choose audio as equipped (CDR24, PCM, PCM w/ Nav, etc)
> choose wheel size > F8 to code.
At this point the status bar should appear, should take ~ 45 sec to code. Once complete it will prompt for correct VIN. Make sure this is correct, especially on PCM equipped cars. Once VIN is confirmed, coding is complete.
i put in 19" wheels, i dont know if 18" would be better (i run 19" OEM on street and 18" on track).
at any rate, i dont understand why the computer wants to know wheel size as TPMS no longer exists. for speedometer and traction control, i would imagine overall diameter is what's important, not wheel size. trying to outsmart the computer, i figured computer will assume 19" wheel take oem size tire and will track oem total diameter. my overall diameter is same as 19" oem (i run RA1).

We did the same, used the 19" OEM dia., even though will run the Hoosiers 245/315/18's on track. I think your assumption on speedo calibration is the reason the computer asks the question.

put 300 track miles and 1000 street miles since i turned off TPMS.
everything is perfect, no strange behaviors at all. it is very nice to FINALLY have an instrument panel without all sorts of warning lights...
thank you TC.
