Hi,

I have a counter of a vw passat that should indicate 7 km/h more at 100 km/h.

here i have the eeprom data of the counter. I tried to adjust it with a program but with no result does anyone know how to adjust it and what I'm doing wrong?



Because the tires are a lot bigger, I would have liked it to be adjusted so that the fuel consumption meter is also correct.

I have now figured out what to adjust. but if I then put it in the counter then the kilometer counter (DEF) appears at the place of the day with the engine running. can anyone calculate the checksum?
