Just wanted to say thanks to he who posted a similar mechanism of bypassing the TPM. BTW these sensors do not have to be referenced to outside air, they are absolute, not relative pressure gauges. The other three are inside. Here's my version:

I assume you don't have runflats on the wheels you run with this container.

I take it you registered all the sensors with the TPMS and then sealed them into the cannister - is that right?

Do you have another set of wheel/tires with sensors that you swap back-and-forth? If so, I guess you have to open the container to separate the sensors to do the re-learn procedure on them when you switch back to your tires that don't have the sensors.

Looks like a good solution for your tires that aren't runflats.

Yeah, not an original idea. The TPM system rarely resets right, got a new TPM reset tool, and what'll I do when my sender batteries fail at the track and can't defeat "active handling". Good idea, but GM just forgot about the rest of the car.

Yes, the senders are too close. I set them first.

My race tires have senders in them - only for emergency if these fail. Then I'll have to repackage these. Otherwise, it's such a relief having a dependable system now.

I once tore a 3" gash in a low profile tire going 70 MPH. Drove 2 miles on it before the centrifugal force collapsed the sidewalls, and I realized what happened. Maybe if I was out in the sticks runflats might work, but, nah, not with a gash like that one. I ordered PS2's today...since it's a performance car, I match the qualities I need for its intended purpose. TPM controlling A/H is appropriate for other types of vehicles. I find it dangerous also.

Would prefer to bypass it electronically. Only info I have is the AN232 transmitter. Need schematic for receiver logistics. That would eliminate these sensors, or I could switch my A/H off aside from other logic input.

 

Therein lies the problem with no sensors in runflats (or, like your experience, even with stiff sidewall low profiles).

If you had taken a high speed off ramp at 70 only 1 mile after your gash hapenned, your sidewall might have collapsed as a sideload built up in the turn and you might have ended up in the guard rail. If you had sensors, you would have known about a loss of pressure and could slow down before you entered a turn.

Additionally, if you have runflats, none of the tire manufacturers will honor a road hazard warranty if you aren't running sensors. In your case, if you have sensors in the tires but they aren't activated, I guess you could get away with them not knowing that your sensors weren't working because the tire dealer would see them in the tires and assume they were programmed.

This is the CYA language on the side of every Goodyear runflat, and even though it's a bunch of lawyerese/legalese, I still think it's good advice:
There are something like 130 computers in a C6. The guys that turn it into an out-and-out track car rip out about all of them except the PCM, the ABS, and maybe a couple others.

The TPMS works through the RCDLR (Remote Control Door Lock Receiver) module and the BCM (Body Control Module), and as you said, talk to each other and the DIC through the computer data bus. For a street car, there may be a way to hack in there and change some code. Butt....with all the problems some real computer whizzes have had trying to hack the Nav System with no results, I think you're in for quite a bit of work to disable the TPMS through software hacking.

Me, I got a tool to reset my senors, and I'm just gonna keep running sensors in my tires.

Good luck with disabling the system, and let us know how it comes out.

Details on how you built it? what you used details pls?

 

3" pvc and caps. Isolate the 3 sensors in a plastic bag and cushion them for shock. PVC glue has toluene, take extra care, I don't know if it might affect the sensors. By this, make many purges to get all the fumes from the container.

I am so pleased to have a reliable system that doesn't threaten my A/H bypass control. With all the problems the TPMS has given me, the relief of anxiety is just wonderful. Since I measure my pressure manually and precisely, any remote possibility of an advantage of the system never outweighed interference with other performance components.

I would liked to have kept the TPMS had it remained discrete and well mannered.
