Good day to everyone.I have a 2012 astra h 1.6 vehicle.I bought an opc speedometer.kilometers high. I went to eepromcu to reduce the mileage of my own vehicle.The eeprom maker deleted some of the information in the eeprom while changing the mileage. the rpm on the speedometer and the needle on the speed section go down directly to the bottom.While reading the eeprom, it could not fully read the device, I guess, most of them see the data as FF.I have to throw its own software on the speedometer to figure it out.How do I reinstall the original software installed on the speedometer?opc speedometer version: 0.502 49/04
