Thanks Michael for the info on Repidscan. Looks useful!
I have just received/configured/'installed' my OVMS device today! Looks
like the "Niro/Kona" config is giving me the most information.. . so I will
start from there.
When I say installed: the OBD cord is running into the holder below the USB
ports (in a way that I won't trip on it while driving). I'll get round to
getting a SIM at some point (I've attached the aerial) - and hope I can get
it working. I will make sure I get the latest code.
One of my work colleagues has dealt with diagnosing messages on the CAN
busses of rubbish trucks at his last job, so he may be a useful resource
for me as well!
Wish me luck.
