Possible to Retrofit TPMS system?

Hi all,

Wondering if anyone has retrofitted a factory TMPS system? If so what is needed?

As far as i'm aware my car doesn't have a TPMS system fitted.
If i cant retrofit then i'll buy a wireless solar one online - about £20, anybody have experience with these on the accord?
The OEM Honda TPMS I think uses input from the ABS wheel sensors measured against a rotation / time value set via a calibration process. I think this is clever, because it uses only software. (edit for clarification: I think it derives an average value from 4 wheels and uses that value to determine deviation)

Aftermarket systems (correct me if I am wrong) use wheel mounted pressure sensor and bluetooth / OIT type comms to a central unit.

I kind of wish that jailbreaking onboard Honda systems was a thing, but as far as I am aware there is no community for that. The programming logic for using ABS wheel sensors to monitor deviations in tyre pressures does not seem all that difficult.

Yeah it would be awesome if we could activate it since no hardware is required.

Oh well, i guess i will just have to buy one of those ebay sets, they seem to get decent reviews anyway.
