Ford Focus RS Tuning Advice
Q: After ID the tool cannot read the original file?
A: There is no tool available that can do a real read of this ECU via OBD. For kess V2 master owners with a valid subscription, the tool will do a virtual read on id and produce you an original file to upload, then write back via OBD.
For all other tool users, its an ECU removal job and BDM read/write.
