I am very interested in this bit of hackery, but I am in Seattle.

Would it be possible to have the OVMS passively record CAN bus  
activity? My plan was to (some day) look at the OVMS source, figure  
out a way to turn it into a very short-term CAN bus recorder, and set  
it to record for the duration of the TPMS tool usage. I'm not really  
sure how feasible that would be, but it seems possible.

I assume that the PVMS might need to be wired in differently than it  
currently is, such that the TPMS tool would still be able to be  
attached at the same time.

I don't even know which CAN bus the TPMS tool attaches to, or whether  
the OVMS can access that bus, so there's quite a bit of hand-waving  
on my part at this juncture.
