I have a different situation that maybe developers have not thought of. There are MANY, people in the RV/Motorhome world that would die for something like RealDash. However, motorhomes are generally set up with a 9 pin J1939 data connection. There are readily available J1039 to OBD2 adapters. Would one of these work to get data for the RealDash? Thanks for the help.
In theory those adapters could work if they are ELM327 compatible. Only way to know for sure is to try. If RealDash is able to communicate with the adapter, but default OBD2 configuration does not work, it should be pretty simple to write specific XML for those vehicles.
But as said, only way to know is to try, and we just do not have resources to start testing on such scenario.
