Hello Guys I have a file of a 500 1.4 100hp bed with galletto in boot mode st10f275 the file is 896kb, I cut 832kb to write it in the obd, this file was modified by someone previously and I would like to do the comparison with the original, someone knows how to cut it in the right way?

using the cut/paste of the ECM,
cut the file from 00000 to 07fff, and save it as file1
cut the file from 18000 to 0dffff and save it as file2
cut the file from 8000 to 17fff and save it as file3

To obtain the file from 832 kb merge with the function of the ecm concatenates two files file 1 and file 2, ignoring the error message.

To re-create the file 896 kb to be able to write to the ecu, and paste with a hex editor, the contents of the file3 to the address 8000 of the file to be 832 kb.

Thanks Cinqueturbo already cut with your procedure.. and to tell you the truth, I am surprised because the file is original, that in practice this person has paid € 350 for a mapping ever made..
