MED17 new checksum eeprom
« on: July 03, 2017, 11:05:38 AM »
Hi all,
Look at this dump. EDC17/MED17 known crc calculation on eeprom is not working on this dump (Alfa romeo med17.3) . It seems there is a new way to calculate it.
At first look, ID is first 2 bytes and CRC is last 2 bytes. Size of block is 0x80 too.
