Renault Megane 1.6 2002 UCH Clone
Hi
Need some help with Renault immo.....
I have two renault UCH boxes here. One is broken, the other one is ok. Both has identical numbers.
The car doesn't start with the new UCH because of immo. Can I move eeprom over from the old box to the new one to transfer immo data? IF that is possible, where is eeprom located?

Thanks for the help in advance

I have no idea... Never done these before. If that is true, then MCU swap would be enough I suppose
(Theoretically it could have both virtual eeprom, eeprom in MCU and external i2c/spi i guess
)
