im cloning an ecu via ktag for ford SID206 reading ok but on flash is giving checksum error and will not let me write flash on new ecu.
Is this something that can be fixed?
attached files from original ecu and new (new ecu read no problem but i need flash from original)

I now noticed file size is different must be corrupt hence why ecu is faulty. would appreciate if someone can send flash file for ford connect 1.8tdci
