[Ovmsdev] Fisker Karma OVMS Support

I'm happy to support development of support for any and all cars. But, we really need a developer with frequent and good access to the car, to be able to do this.

It would be good to first confirm feasibility. Do you know what sort of CAN bus connector the car has? Presumably OBD-II? Then, using a CAN-USB adaptor (or OBD-II adaptor in monitor-all mode), try to get a trace of what is happening on the bus (while car is idle, while car is driving, while car is charging, would be good). If the car works on a request-response arrangement, what are the PIDs you are getting a response on?

Regards, Mark.

The CAN system is setup very similarly (from what I can tell)  to that of a Volt (about 49 PID’s can be read from my generic scan tool and I have a small list of PID definitions.  This would be a huge benefit to Karma owners as the Command Center in the car is not every useful and if a OVMS is setup in conjunction with a tablet Fisker owners may have a much better UI to interact with the car.  Anyway I will help in anyway possible.  Thanks A
