Has anyone seen these cheap TPMS systems on ebay

Has anyone tried to see if these can be modifed to output voltage / CAN Bus so it could be connected to a DL1?

At this price I'm not sure how acurate it would be, but might help some of of the lower budget race teams.

Has anyone got any ideas how I we could log information from a device like this

into a DL1. It's such a cheap solution, it would be great if we could get 5v, serial or CAN data from it

All depends on how the sensors connect to the display.
They may talk via serial data maybe RS485 or 422. if so it will be difficult.
if they just output a change of voltage like most over sensors, its just a matter of tapping and mapping the voltage to the PSI, and connecting to a DL1 input.
