I purchased the OVMS (v2) with the intent of writing custom firmware  
that would log CAN traffic. I assumed that I'd need compression,  
pattern-matching to log only a subset of the data, or some other port  
to which I could stream the data (DIAG or USB). However, I never did  
get around to writing any new firmware. I know the memory is limited,  
but I hold on to some hope that intelligent filtering, or even just a  
histogram, could provide useful data. In fact, perhaps an initial  
phase of gathering histogram data, followed by targeted logging,  
would prove useful - assuming easier options aren't already  
available. Has anyone worked on custom OVMS v2 firmware for something  
like this?

I'm looking forward to the OVMS CAN-USB, but I suppose that won't  
arrive soon enough for your project, Tom.
