Hello Guys!

So I have purchased some hardware for reading writing the EEPROM via OBD in order to alter my dashboard's electronic indictaions from miles to kilometers of my car. In another thread of this forum after a lot of time googling I found a post from another member here giving the address and value to do that. Surprisingly it has worked on both models of Tucson 2016 & 2018.

however, the dash has an electronic speedometer which even though the indication of miles next to speed number has changed to kmh the speed number it self is still calculated in miles!

any ideas how to fix this?

posting a picture below


any help is very much appreciated
