I report a new news, today I have written modified file in case cx300d in the obd diagnostic connector, I have read and written and everything worked perfectly,
I have to admit that the mod file was wrong, I wrote with transdata the ori file read with mmcflah in eobd and the ecu came back to life, later I re-wrote a new mod file with mmcflah in eobd and the write was correct, mmcflah works on this ecu correctly
