unfortunately I can not access any type of files I guess because I'm a newbie anyway, I think I understood that with reading the obd read only memory where the content of the map, and if in the obd you should freeze I miss all the rest for you to restore in bdm ,I gather that converebbe to do everything in the bdm so I keep the backup and maybe for touch-ups I do all of this in the obd so if I get stuck having the backup in bdm I can restore it,I believe that it should be so coreggetemi if I'm wrong sorry for the impulsivita and I ask you for delete egr fap and code key instrumentation occorerebbe or just always kess+ktag and other software thanks to all
