Guys found the problem, the ecm calculates the checksum in the wrong way, in fact I noticed that calculates both in the first part of the file at the address 0000E2 viewable to 8bit, and in the end a 16-bit motorola, the part that's wrong, and the first where it touches something that must not touch it.. in fact the ecu is not me that is found to not even making the diagnosis, and as if become dysfunctional.. I noticed that the modified file by importing it in the BDM and doing the checksum correction tells me "checksum ok" but with astonishment that by importing the same mod files without a checksum correction BDM only corrects the final part to 16bit in the same identical way that makes the ECM, leaving intact and original the initial viewable to 8bit..
not convinced I've uploaded the modified file without correction of the checksum on Winols and I noticed that it also does the same correction of the BDM, the problem was upstream in the file you created with the ecm where it was changed to a string to 8-bit..

Here is the mod file
