fg galletto 3 v53 problem

[kospoz]

hi people i have bought this tool from xcar360.com and it is working good but there is a problem.
I found it when i try to modify one simos pcr 2.1.I did everything like manual to unlock the eeprom and the program said eeprom unlocked ok.Then i try to read it via obd like the instructions but i failed.
I want to ask if on bench i have good can communication why i can not with obd too?
There is another way to read write this ecu on bench?

Hi pcr 2.1, you can read and write ecu even without unlock the eprom via obd, but only ori file. To use mod file must to unlock eprom.
