What do you mean? How to change the mileage?
Yes

What DIM do you have? Year?

For example xc90 2007 with mcu mask 0L85D

I think, the algo is +/- same in all DIM

I'll get back to you on this when i have my laptop, don't remember exactly how to do it. But there are software for it and also it is not hard to do it in hex editor.

I no need to change, I need convert odo data from eeprom to int value

Read UEM with im608 and program remote
Only new with codes label.

Someone have any clue how to program used fobs? I know its possible if you have the old UEM with keyfob to move fobinfo from UEM to another used UEM. But thinking of keyfob without known UEM? Theres a encryptioncode i think is needed for it to work afaik?

It's impossible

Thank you! Do I have to desolder the chips to read/write them or connect these tools to some pins on the CEM? I am experienced in programming but only things like web development, SQL, etc or sysadmin stuff. I am noob in embedded systems like ECUs but I am interested(in this field and also in saving my CEM)

You don't need to desolder the mcu, just eprom.

Hello,
2006 V70 CEM - 31394157
Trying to get my CEM pin using T5Luke's UDScrack

Getting bunch of errors, not sure if it's working right
