Modded eeprom write succesfull, but the mileage did not change. After writing i disconnected negative side battery for 1 min, but also no effect.

Mileage is 146.304 actualy, not 146.300 like I said.
Maybe that is why?

Thank you. I see. It won't be as easy as I tought it would be :wink-new:
I will upload another eeprom soon for other new instrument cluster for the pin to swap it over and use the car.
Then I will test change mileage on old half broken cluster. When I know how to do it I will do it on my new cluster for real:smile-new:
When I have questions etc about how it works. Can i ask you?

Many thanks.
