Summary:
FC200 has more protocol
FC200 can only do checksum fix online, checksum won’t work if the subscription expires.
FC-200 works only on Bosch ECUs, So for Magneti Marelli, Continetial or siemens pcmtuner is better
If you want to used for dpf,egr, adblue off and remap, PCMTuner is better
FC200 only some BMW ECU can be done via OBD
PCMTuner v1.21 cannot do BMW ECUs (EDC17xx etc)
In conclusion, depends on what is the main purpose of your buy.  FC-200 could be useful for BMW ISN from Ecu or maybe for some Ecu cloning, but only some of them because most of MEDC17 needs adaption of OTP and password or immo transfer for successful cloning. If the main purpose is Chip tuning, PCMTuner is a better buy because it can calculate checksums and it is cheaper.
