Tc help with drag pack
when i put my drag pack on. my when my light for tpms or the size of my tires makes th elight come on i cant turn tc off all the wya. stable trac stays on and if i get a bit of spin off the line it gets a crazy death woble that where the car is trying to straighten me up and its not safe at all.
anyway i can disable all that crap. it will only let press the tc button 1 time . tapping 2 times doent work or holding down down work when that tire light comes on.

That's interesting. I didn't put tpms in my c5z fronts and never had a problem disabling TC (you really should only get TC on and TC off options with the TPMS showing XX).
This sounds like the car thinks you've got low tire pressure instead of missing tpms. Maybe you do need to build a tpms capsule. Subbed because I want to see what you figure out. Good luck.

The simple and safe solution is to trailer the car or change wheels at the track. Skinnies and slicks on the street are a recipe for problems. When a drag pack without sensors is only used at the track, the TPM system doesn't have enough time or distance to cause a problem with TC or AH.
Although I've never tried it, driving for no more than 15 minutes at a time and shutting it down, before starting and repeating it, might be enough to constantly reset the system.

Strange. My race wheels have no sensors, and never had an issue disabling TC/AH. LG sells a box that disables it. Sounds like you are getting a low pressure signal. If you get no signal dash just says XXX and says check TPMS but has no effect on AH/TC on or off. At least it doesn't on my 06.

well talking over with my buddy at ky speed. he thinks it may be the tire sizes causing it and not the tmps. cause both front and back are like 26" tall vs the offset. but that pvc thing will work. at least that will elimnate it.
but sometimes i can drive for 100+ miles and never get the tire light on the drag pack and sometimes it dont make 5 miles. but as soon as tht light comes on i cant tap the button 2x or hold it down. just tc off mode
dennis u the man. that will work. if thats not the cause i nkow its the tire sizes.

What are the tires with TPMS set at? If they are low, and you park within about 20ft of them, it will sync, read low pressure, and cause issues. Make sure they are aired to the correct level.

i cant haul 4 tires . bolt on my skinnies and drive to the track and then bolton on my rears. if i could stay 20' from them at all times wouldnt been a issue. but thats cant happen. its only when the yellow/orangish light comes on when it wont let me select. up till that happens it works fine

Pretty easy to do if you keep your head in the ball game. The first time, I pulled over and actually stopped. After that, just killing the motor and restarting on a roll worked fine. Little or no lost time. Good stuff HOXXOH

The 05 a4 trans is different then the manual , I had mine read in the canister then moved it to the back garage and put in the tool box so it couldnt read because to far away drove hundreds of miles over several months and everything was fine could turn AH&TC off, but the first time I really jumped on it in a street race it went to tc off only xx and couldn't turn AH off, my car runs straight with both off and with AH on it is all over and hard to keep in the groove from AH counter moving by breaking one side to the other.

I guess it would be too damn easy if they were all the same. That would take all the fun out of it....right? I went from my office to home without any TPMS lites. 15 miles and maybe 20 minutes. Mine's a 2013 M6 grand sport.
