    Default Audi 4E0 A8 W12 Cluster swap

    Hello,
    Car Audi A8 2005 with original cluster 4E0920930E (with Europe scales) changed to new one 4E0920951K (with Miles speedometer).
    Speedometer scale from original cluster (in km) installed to new cluster 4E0920951K.
    Could you please help to transfer speedometer calibrations from old eeprom to new one or fix checksum?
    I tryed to copy experimentally data from old eeprom to new eeprom adresses from 151h to 2A7h. Speedometer comes correct, but checksum appear (def on odometer display and error 16348)!
    attached eeproms:
    A8 W12 EU dash 93c86 - original cluster
    A8 W12 USA dash 93c86 mod - new installed cluster
    4E0920951K_experiment4 - new cluster with checksum error (as described above).
