Claas Scorpion 7044 hours

[bendix2]

Hi,

now I have Claas Scorpion 7044 dash, 2016 year.
Dash: CC02.0007.20 Kontrollleuchtenmodul ID: 99K1516 IA: 9347

I need to change hours, but I don't know, where stored hours.
I read PIC16F1947 processor and 5AE 1425 eeprom.

Some people think maybe 5AE 1425 eeprom (he think it is same as 25AA256)
Some people think maybe processor, but there are think data memory, but my data memory full FF.

PIC16F1947 read it Beeprog+. Beeprog+ make ".hex" format, but I save seperatelly to only_data_memory.bin and only_program memory.bin.

Current hours: 8416.3 h
I need: 4050 h

But it would be a huge help if I knew where to store it too.
Maybe this type on ECU, not dash?

Please help.
I attached everything (photos and files, no password.)

I have the same situation with same instruments cluster. Data memory is full FF. On table IC shows only dashes instead of hours. Maybe is it stored in another modul?
