This reads flash by 6 byte code:

Hello,

I can help you modifying that flash, i have all neccesary data to change and information.

But i have no idea how to write it back to CEM and this is an issue!

If you want you can send me the flash.

Thanks!

Thanks

CEM Data Manager.jpg I made this long ago for my self. It works, for me and i hope for anyone who needs it to copy his own CEM. For just changing config, better take the other tool and write only the config to your cem by dice... https://www.matthewsvolvosite.com/forums/viewtopic.php?t=85611&st...

hello everyone

Ah yes. A scammer

Spotted a mile off.

I am also interested on making an app which can write back by DiCE the modified flash into the car, thanks to T5Luke, on 28f400 cem that is possible but in the M32C CEM is still not solved.

What did you do ?

Curious and following. Also, if you have timing issues with the pi, you will have to set GPU and SOC speeds in the config.txt. Some of the GPIO timing is affected by both. Pi4 is the most blatant "offender". I am using the older and slower Pi 3B 1.2 rev, it is generally slower, but I've o...
