Hi!

This is amazing work. It is always great to see more in open source ECU tuning. Unfortunately I sold my Elise some years ago or I'd be jumping in to collaborate.

I do have a feature request / suggestion: have you considered using J2534 (Tactrix OpenPort 2 being the most obvious hardware)?

This would solve your K-line + CAN splitter setup on white dash cars, as the hardware supports both. It's also just more common off the shelf hardware.

J2534 is an SAE specification that you can download online - it was designed to force manufacturers to make their dealership flashing tools all work with a common cable, with some varying degree of success. The spec basically describes the API exports from a per-device driver DLL, and then you call into that DLL to perform each function (open connection, read/write, CAN filters, etc.). We wrote a J2534 driver for Python UDSonCAN in our VW_Flash project:

https://github.com/bri3d/VW_Flash/blob/master/lib/connections/j2534.py#L40 and https://github.com/bri3d/VW_Flash/blob/master/lib/connections/j2534_connection.py#L7 .

It would need a little work but should be very straightforward to port down a level to python-can and add some K-line primitives.

This might help to expand your user-base as well as make your day to day easier than your current many headed OBD hydra :)
