I've uploaded a new version of the FG2 IPC Comms program to...
https://github.com/Jasoroony/Ford-Fa...n/extracted_fw
It now has experimental support to read and write the FG(I) Cluster EEPROM. It allows most of the overrides I did for the FG2/X, but don't expect your non-FPV Cluster to display the FPV splash screen, I just don't think it's in there to do so. Unfortunately MK(I) Clusters with April 2010 (or later) firmwares are not supported.
Since I don't own an FG(I) I can't say if copying the EEPROM from your original Cluster to your spare Cluster is enough to "clone" it. Maybe someone can try? Please don't use this software to write data to your original Cluster.
