I actually had the most hilariously bad idea on how to make a TPMS system work.

There's various aftermarket TPMS setups of varying quality, but most of them output to an LCD or LED display with 7 segment digits. So you just have to solder the terminals driving the 7-segment displays to a multiplexer and have a chip read that!

I was thinking about that too. I think I saw a blog of someone doing that. Maybe you can tap the data lines of the radio transceiver on one of those tpms modules and read the configuration init sequence then duplicate it with your own hardware.

One way or another, for the price of the Stack TPMS setup, I can get a lot of cheap aftermarket TPMS stuff to try to reverse engineer.

I've seen talk of zigbee TPMS senders, which seems like a good solution for this.

Then share the fruits of your hard labor with me and spoon feed me all of the information. =)

Well sure, I don't see my emphasis ever being trying to make money from the electronics side so after I lathe my square tuits (... yeah, sorry, I think I'm funny) I'd be happy to share my terrible code for free rather than getting stuck trying to support a paid product using it. I found a couple sources of people who did reverse engineer OEM TPMS signals for various things, so it's obviously not impossible, it just remains to be seen if I'm competent enough at that sort of thing.
