I've been rading about C6 owners having issues with the tire pressure monitor system in racing , wheel change , and low pressure situations. My question is: can the system be programmed to eleminate the sensors or "fool" them into thinking the tires are fully inflated, even though they may not be, or even though the tires no longer have the sensor in them. Before I get the "don't remove the sensors because of safety" people chiming in, remember, we wouldn't even race if there wasn't some risk involved, where's the fun in that. Also, I've heard alot of people complain that they bought expensive wheels that are now useless because of the system, so thats why I ask.

 

I'm not a tuner....

Butt......NO!

Big Brother knows better than we do about what we need to be safe.

Remember about 4 or 5 years ago when a bunch of Phord Explorers were flipping over and killing moms and their kids. Phord and Firestone got their butts sued off because stupid people never checked their tire pressures. When the tire pressures got low and they looked up from dialing their cellphone and found they were veering out their lane and made a rapid steering input, the low pressure tires started giving them handling problems and they overcontrolled even more, and ended up upside down.

Congress passed a law so stupid people (I guess I shouldn't say that - let me change that to "people who don't have time to check their tire pressure") will be warned when their tire pressure is low. Part of the law is that the system can't be disabled. It's designed to be a nuissance, to give messages, turn on warning lights, and possibly do stuff like turn your Active Handling system back on if you turned it off.

Starting next year (Sept '07, for the '08 model year) every vehicle less than 10,000 pounds will have to have a TPMS similar to that your C6 has. Corvette has been way ahead of this law, but it was always an "advisory" system. The C5 Z06 came without it activated, and you could turn it on if you wanted to run sensors. The C6 is "mandatory" (like the law will require starting next year), and you can't deactivate the TPMS.

So......NO! You can't turn it off, disable it, program it out, or otherwise get rid of it. Just do like Congress tells you to do!!!

UMMMMM....ok...well...I guess we all should take off those headers, replace the factory tune, all the factory parts that we've taken off and drive EXACTLY the speed limit as well.....

 

My car displays check tire monitoring system but still allows me to run without AH/TC on. Does anyone know if this is short term? I was able to run to full track days on a road course without it interferingwith my fun.

 

From what I understand, that is not the norm. I've heard it'll go into limp mode after a few cycles with no monitored pressure.

 

Does the car display a warning while in limp mode? How would I know?

Actually when I went last week. The drive to the track I had no problems except when I arrived, I had a check tire pressure monitor system. the dic showed XX.XX or something like that but I ran all day with AH/TC off.

The next week, temp considerably dropped and one of my factory tires went to 23 psi. I park my car right next to my stock rims with my racing wheels on and I guess the computer received that signal. I had a warning come on every so often driving to the track and everytime I started it. The car remembered the low tire psi. I did turn the car off yesterday about mid way to the track so there wasn't the continuous time the week before. I did have a yellow warning the whole day yesterday but was still able to disarm AH/TC.

I heard the 2006 may be a little harder to foul.

Just my experience with my 2005

 

The warning should come on, power will be depleted and eventually the car will shut off. It'll be like you're running on 4cyl. I went into limp once and it scared the beeegeezzus outta me. Thought I had blown the engine, was just a broken valve spring,but it kept it from doing more damage. With the TPS, I don't understand why it's not optional.

 

I just edited my last response. Also, did you mean valve stem instead of spring?

I definetly did not have a loss of power at yesterday event as I did quite well.

These cars are alittle complicated with their gadgets but so far it hasn't interefered when I switch out wheels.

It felt like a worse case scenario yesterday because my stock wheel had gone so low but I wasn't even using it on my car. My first time out my car maintained the last readings my stock tires had sent until the car was on for about 1.5 hours and then sent the service tire pressure system.

 

How long total was the sensored tires off the car? Was trying to figure out if that warning about the car going into limp mode after so many cycles without a reading was correct. Sorry for any misunderstanding.

 

This past weekend they were off the car about 2 days. I drove about 350 miles total. No limp mode detected. Also did the same thing about 2 weeks ago. I put my race wheels on Friday for 1/4 mile and then for road course Sunday.

The only difference was that the temp really dropped one night so my car received a signal from stock wheel saying low PSI of 23. So the 1st weekend I had no warning light but the second I did because of this low pressure signal received by my car when parked in garage saturday night.

Either weekend, I felt like the car was performing optimally. I just had to reset the low pressure tire warning often this past weekend. On the way back from the track the car finally recognized the wheels were not sending a signal so the yellow warning light disappeared but the DIC said service TPMS.
