Yep, its another name for the same thing, I don't know the exact difference between FCS and CRC but I used to work with simular code using XOR in a serial protocol and they called it FCS. Cyclic Redundancy Check (CRC) is used for the same purpose as FCS.
When do you plan to start with CDC emulation, with the present info it must be possible to fake a CDC? When interfacing with the HU you can try to test some things that are not very clear at this moment. Of course you don't have to fry your HU just to satisfy my curiosity.
