Race car TPMS for less than a new game console?

I'm looking for a TPMS system that meets these criteria:

1. Uses sensors that hang from a standard TPMS valve stem
2. Costs under $300.
3. Sends data out over CANbus for logging/display. An included display is not necessary and would obviously be very bad for staying under budget.

Does such a thing exist? Maybe a junkyard-sourced OEM receiver used with programmable sensors?

Looks like Autosportlabs is working on this same problem and the OEM/junkyard route is the best way to go: I'd have to find a car with a separate TPMS receiver with CANbus, reverse-engineer the communication protocol and then move all the stuff across. They're looking at one from a Fiat 500, looks like the Kia Optima also has a system that fits the requirements.

Might also want to check out some of the systems that Ford uses.

Not sure if they can data log, but there are several standalone tpms setups for trailers that would let you monitor pressures.

The standalones do bluetooth. Here is something... cost effective and interesting. https://www.indiegogo.com/projects/fobo-tire-world-s-first-all-bluetooth-smart-tpms

sort of fits the bill.... add up top 24 tires, BUT uses funky valve caps as the sensor.

display with 4 sensors is lower then your budget @ $270

The bluetooth and hopkins units can't do the job unfortunately, It must output data to the data logger over CANbus, and a display system that connects to the data logger with Bluetooth is already in the works (I don't think the data logger can handle multiple BT connections or log data received over BT).

If anyone can find info on Ford OEM systems I'd be interested. I have to get the part from a USDM car anyway because the JDM cars that are common by me don't come with TPMS, so any manufacturer is OK, although I'd prefer a system from a common car for a more futureproof setup.

It's hard to meet that price point. Most of the race car systems on the market today use some pretty expensive sensors. You might be able to hack something together using OE parts from a junk yard maybe...

Thanks for this link. I was just thinking about this for my trailer. Will provide substantial peace of mind when I am doing longer trips with the trailer!

what about itpms from atbs technologies, I know virtually nothing about it, but it looks somewhat interesting.

Thread resurrection, anyone found anything close in the last 3 years? After blowing a tire in an autocross run on the weekend, resulting in a destroyed tire and a slightly damaged wheel, I really want TPMS now. There are even decent and affordable systems that also read temperature available for $50~$200 now, but unfortunately only show data on a display. This info seems way too valuable not to log. I'm almost ready to settle for a standalone system just to keep my tires and rims safe...almost...

itpms is basically the same system some cars have that uses wheel speed sensor differences to infer tire pressure problems rather than measuring tire pressures directly.

This looks like the best cheap standalone system:

I use the ones with the valve stem cap sensors, because I track multiple cars and sets of wheels.  Anyway, I have been using them for three seasons now and they work great, albeit display only.

What I want to build now is my own IR temp sensor array to get on-track variation in tire temps across the treads.  Talk about taking the T&E out of suspension setups . . . .

As often as I check pressures when autocrossing, I can't imagine pressure being so low as to lose a tire.

Agreed, it sounds like a catastrophic failure that TPMS likely won't help with on an autocross course.

Once I'm done tuning the pressures for a set of tires I generally don't check pressures between runs...this tire was ruined by nails on the track, but I'm thinking that if I had an alarm go off as soon as the pressure dropped, it might've saved the tire and would've prevented damage to the wheel.

Any links to a cheap valve stem cap and display? Just put run flats on the truck and it doesn't have tpms.....

Here's one:
