The CAN cable is not shipped with FlashScan or AutoCal. It is available as on optional extra.

The secondary CAN interface is not implemented. In future it may be implemented if/when EFILive offers integration to third party products via the secondary CAN interface.

The switch option allows a remote, momentary switch (between Switch and Ground, i.e. pins 1 and 2) to be attached to FlashScan or AutoCal that can be used to start/stop data logging. That is useful for starting/stopping data logging via a dashboard mounted switch.
