Have tried searching and came up with mixed results, but i need a definitive answer on whether you can run without tpms sensors in wheels, and not lose any functions on the car.

Surely there must be a way to disable it, as tracked cars come in and change wheels and tires, not just tires, and they don't sit around and wait to program the sensors.

Car is 08 Z06.
Will not be using runflats

I understand about the search... There is no way to disable TPMS reaction. If you have a 2nd set of rims, get TPMS for them and a tire training tool. It will save you a lot of headache later.

If the car doesn't see a TPMS sensor after about 40 miles, the car will go into limp mode, and you won't be able to drive the car to its fullest. You WILL overheat your brakes.

Tracked cars can get about 15-20 minutes of track time before the limping starts. If you park the car next to the "trained" wheels, you may get lucky. The system will see the wheels near the car, and give you another 15-20 minutes. This may be what you see from others at the track.

I swap out my DR's at home which is about 50 miles from the track. I race all day and then I drive home another 50 miles no problems. From my experience, the only time it will go into limp mode is if the tpms communicates with the car saying you have 0 PSI.

When I go to the track, I get a service tire monitor notice but it does not affect the performance of the car whatsoever. I can diable TC, enable competitive mode and disable TC and active handling with no issues. I do not have sensors in my DR's.

So let me get this straight!!! Your want to disable your tire pressure monitoring system......and you want to run without run flats!!!

My question is why would you not want to know that a tire is going down?

If these tires and wheels dedicated to track use only......I think you need to let the monitor zero out. If your running them home from the track...I would want the pressure monitored.

I don't screw around with this. I swap to Hoosiers for track days several times a year, put sensors in them, and have a Bartech tool. I drive to/from the track on these, and since non run flats, really the ones I'm wanting monitored. The Bartech's a handy tool to have, as my other cars have TPMS too, and good for tire rotations.

I have been driving and racing for years without tpms, and when not using RF, can feel even small changes in tire pressure.

Aussie Vet

What year model is your Z?

Do you know of anyone else doing this also?

I have run w//o TPMS sensors since day one. No problems at all. The light on.the dash is no biggie for me.

I am curious about this too...

When I swapped the wheels out, they weren't programmed. The DIC indicated they were at 27 PSI on all four corners. It wasn't until I got the tool and messed with it did it eventually start to realize that nothing was programmed.

06...and I dont know anyone personally but guys have chimed in as well that do this.

The car will go into limp mode IF it receives a change in air pressure. If the sensors are off it doesnt get a signal from them so it gives the "service tire monitor" warning and you'll see xx on your info center for the specific tires that are not giving the signal.

The only time my car goes into limp mode is when I get new tires since they have to remove all the air from inside. the tpms reads this and sends the signal to the car. So once I start driving it again and the sensors read that there is air pressure it goes back to normal.

Aussie Vet

Thanks all for their input, and Triblk6sd and H8VTEC, do you know if it is the same for an 08 model?
If it is just a light on the dash it would not worry me at all, just don't want to go into limp mode or lose options on traction control.

cheers

gotjuice?

Exactly the same for me. Mine is an 08 with no issues except for the light/message.

You have to reprogram the body control module to turn it off. None of the work arounds seem to work 100% of the time. For every person that says they don't have a problem there others that do. The only way to get rid of it is to change the BCM module software.

Aussie Vet

Great to hear, fingers crossed mine is the same.

Aussie Vet

Thanks for the info, how hard is it to do this and what i needed?

H8VTEC

Also just an idea, some guys made an "air box" with TMPS installed and programmed to the car and drive with it in the trunk. The box I believe were made out of PCV piping and sealed so it doesn't leak.

Well, its hardly the end of the world given that for the first 100 years or so of automotive history we had no TPMS. You could always tell when a tire was going down by the feel of the car. I am not against TPMS, I think its great, but its like electric windows, heated seats, etc, my God how did we manage?

BEZ06

Yeah, but we didn't have runflats!!

With a runflat, if you're running straight down the highway and lose air pressure in a tire, you just won't notice it because of the stiff sidewalls.

Butt....when you take the off ramp in your normal spirited manner and build up a sideload, you might end up in the guard rail and wonder why!!!

So....tire pressure sensors and your TPMS are much more important when running runflats than old soft sidewall tire technology.

The C5 Z06 didn't come with runflats and the TPMS wasn't activated in the Z06 as it was in the base C5. If you put runflats on the car you could have a dealer activate the TPMS with a Tech 2.

However, when the C6 was coming out the U.S. gubmint was just starting to require TPMS in all cars, so it can not be disabled in the C6.

There is only one person that I have ever heard of that has the programming knowledge and capability to reprogram the C6 BCM, and if you do a search in the AutoX/Roadrace section of the forum you can read that the results may not have been very successful.

Problems with running no sensors seem to be different in different model years, so Aussie Vet, I think you're just going to have to try it with your car to see what happens, mate.

However, I suspect that sometime down the road (track!!) you'll run into problems. Here's a link to a thread that discusses the issue. You can see that David Farmer has run for years with no sensors, but at a recent event he finally got bitten:

This thread is almost too long for such a simple problem. Pull the sensors and go from there. Limp mode? For TPMS sensors? Really?

BEZ06

It's absolutely not a problem for street driving.

I put up that link in my previous post - read that, then post up to David Farmer "Limp mode?...Really???"

Because for the track, yeah - REALLY!!!!

I had a hard time programming my sensors one time at the track, so I just went out on the track without programming them. Turning in at T1 I had the brakes jerking the car around, and when I tried to accelerate out of the turn the throttle wouldn't respond until I unwound the steering and had removed virtually all lateral G's, then the car would finally respond to my right foot.

I was lucky there was nobody behind me or they probably would have smashed into my tail end!!! I limped around the track, came into the pits, screwed around with my TPMS tool and got the sensors programmed, went back out on the track, and had no problem for the rest of the session.

So....yeah - it's a REALLY BIG deal on the track!!! Many of us have experienced the limp mode problem, and like my experience and that of David in that link I put up in my previous post, it makes the car undriveable and bordering on unsafe!!!
