Can someone tell me what the options are for getting CAN-Bus integrated with the Pro MK1? I think it needs an additional expansion card, correct? Is this expansion card still available? If so, what does it cost and how many CAN-Busses / Channels does it support? We would like to integrate an MK1 with our Megasquirt MS3X ECU if doable.

Thanks much in advance.
