Title: Med9 checksum
Post by: jastr on May 27, 2018, 12:31:28 AM
Are there any tools to calculate med9 checksum on vags? I know the eeprom tool can do it on the eeprom but any other tools that can do it on all the areas?

Any tool that writes MED9 will do the checksum too. It's not needed.

im use if you use mpps it dose the check sum while flashing it to ecu, or if you have winols you can check sum using that, and i think i seen a med9check sum program on here some where

Winols requires you to have that license to checksum it.

Why do you need to BDM? But yes, BDM tools should still checksum the flash.

jastr what do you mean, i added the exe file for checksum for med9 all you do is drop and drag file to the exe and it will make other file with ok at the end

Isn’t it just for checksum eeprom?

Don't know much about med9, but i am fairly certain the checksum algorithms are very different, and it is unlikely the same tool will work on both eeprom and flash.

That .exe is only for the EEPROM checksums.

If you BDM you need to use Winols really to check sum it 1st then flash on..

If you want to flash your ecu without car you can also make immo off and then write OBD as usual...
