2020 Corvette of the Year Finalist (track prepared)
C3 of Year Winner (track prepared) 2019
C7 doesn't require TPMS, why not just eliminate from the wheels you are using? They relearn really fast anyway, are you doing hot pit tire changes or something (seems doubtful). There is a procedure that will supposedly allow you to relearn tpms position by going to the TPMS display and holding SEL until the horn beeps. You still have to drive around though for them to "learn" the correct position.
Personally, I would just swap wheels and hit the track and let them relearn automatically.
Most of the time the TPMS will relearn within a quarter of a lap. Have had them finish the relearn just after exiting pit lane. However, ONE time only I went a complete day with the sensors not being detected. After the car sat over night it had trained itself to recognize the sensors. It isn't a big deal as the car doesn't need them when you are on track. I ran without sensors in my track wheels for 3 or 4 events and never had an issue. All I had to do was reset the warning that came up every so often. Nice to be back to the C5 type of operation where the car won't take offense if the sensors aren't present and just warns the driver there is an issue and lets the driver deal with it.

Its not relearning, I've driven 10 miles... MAybe it;s because I put a Chines made TPM in one of the wheels and it's not picking it up?

Bill,
Last time at track, I didn't know I broke one of the tpm inside the wheel ( i think i did it from dropping the tire on the ground from my truck bed) and I got a (-) reading on my DIC.. every time my wheels slipped on track (which is often) it started to brake and ruined my lap times..
If I don't run tpm's i feel like this will happen again, you're saying there's a way to "clear" them?
So the same basic tool that you would use to trigger the sensors on a C6, works just fine on a C7. You just have to put it in learn mode. I do it all the time because I also want them to be accurate from the get-go, I'm racing too
Whoever said you don't need the sensors, I disagree. I mean depends on your definition of need. But considering the ELSD references the tire temperatures via whatever crazy algorithm they have going on. The sensors themselves don't read tire temperature. There's some kind of voodoo going on there. Not exactly sure how it works but I suspect it's got something to do with the car knowing the ambient temperature, the fact that when you start the car the oil temps and stuff are cold and then looks at the change in air pressure at the tires as you drive. We know that air pressure goes up 1 lb for every 10° of temperature increase. If the car can't reference the air pressure I don't think it can reference the tire temperature. And since the diff calibration is different depending on temps I'd say that's kind of important.

This would be a great question for the "Ask Tadge" section, if he'd be willing to provide some details on the relationship of the TPMS with the eLSD.
I’ve never had mine on my 2016 ZO6 relearn. I bought the tool a few years ago for my truck because I was swapping wheels in the winter and it works on the ZO6 too.

Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
