    As Nio write, Checksum is calculated for Flash not for serial eeprom

    I have the chk correction for flash (winols) thats not the problem, but
    If i make some changes in 95040 (i want to test some tricks...) i have to correct the checksum, otherwise the car wont start, i tried it already.

    Try this

    Write the new eeprom, don`t start the engine, clear error codes, now the cs should be calculated
