Definition problem with a 06 STI eudm.

[giangi]

Hello, i'm trying to read a STI 06 eudm ecu, ecuflash reads perfectly the rom but at the end of reading the program tells me that there is no valid definition for this rom, please, could somebody help me? Thanks in advance.....

Your ROM has been modified by another program. The calibration ID at offset 0x2000 should be 'A8DH200Z' but the one in your ROM has 'A8DH20 '. If you fix that with a hex editor, you'll be able to read the maps. You can download the original unaltered version of your ROM from http://forums.openecu.org/download.php?id=522.

Thank you very much for your help, now i've solved, only thing not clear is that Ecuflash when loading the file tells me that one or more checksum values are incorrect, and ask me if i want to correct them? Should i let Ecuflash correct them? Thanks again for the help....

Changing those two bytes using a hex editor outside of EcuFlash invalidated one of the existing checksums in the ROM. You must let EcuFlash correct it.
