This is an area I know very little about so looking for some advice please.
I don't want to get into heavy changes but looking to set up the GMT auto change, throttle response, rear brakes, battery replacement etc.
What's a cost effective option?
OBDeleven uses android and I only have iPhones however I do have an android with no SIM card - would I be right in thinking that you only need it as an interface and therefore don't need a network connection.
