The Nannies
I track my car pretty vigorously on road courses. Each time I leave the paddock, I shut off the electronic traction control and stability control nannies with the switch on the center console.
The last few track days, I have noticed that about two thirds of the way into a session, I get a message of "tire over-pressure in the right front" and then the nannies switch back on. I then have to fumble around to turn them off while driving the car. I think that when the tires reach 40 psi, it triggers both the warning message and the nannies, and you have to shut them off again manually.
I recently switched to a second set of track only wheels, which have no TPMS sensors in them. My question is whether the lack of TPMS will even allow me to turn off the nannies at all, or whether I'll just get a warning light.
Anybody know?
TIA,
Terry

How upset the nannies get will depend on what year car you have, he seems to have it figured out. PM him.
You can put some info in your profile so others can help you more easily.

I've read low TPMS light will NOT allow you to turn the 'nannies' off, and by more than one guy, so you're probably screwed... unless somebody knows a way to defeat the system. But wait until you hear from a member with actual experience 
.
I was wondering if a high TPMS condition would trigger the same, but you already answered that, saying you could turn them off again. But that's an easy to correct problem, even if that wasn't the case. Good luck.

I've seen here on the forum a way to fool the system for racing purposes... Remove the sensors from your race wheels and install them in a pressure vessel, like PVC pipe, pressurize to 30, then secure them inside the car somewhere.

Unfortunately, my TPMS's are on my street wheels; I was trying to avoid buying another set. I'll run this weekend with the nannies on, then fork out for another set before then next event.
