I just want to send Thanks to all in this thread. It is very valuable and give me a quick boost start to read out information from my ECU, V70 2006 BiFuel. Denso ecu wuth a sh7055 cpu. I started off by the simple scripts and code dikidera provided. They run successful and was able to read out flash....

Continue on my journey in Denso ecu for a V70 BiFuel 2006 Now when I have the rommonitor working it is easier to test code running in the ecu. Now with write support to external flash, eeprom and internal flash. Please, note that it is very easy to brick the ecu when replacing flash content. If new...

Next small step with my V70 BiFuel 2006. Readout of CEM-L with M30855FW cpu using a SBL. Only read implemented so far. Decrypt of eeprom data is implemented but not verified that data is correct. It looks good, much more 0 values now and not just random. Parts that was FF (unused) now looks like ran...

Implemented eeprom and flash programming to my V70 BiFuel CEM with M30855 cpu into my SBL. Possible to read and write complete cem over can. Still running on Raspberry and SocketCan Reading flash and eeprom in car $ python3 sblflasher.py Bus sleep........................................................

Some more analysis of eeprom data. This information is probably already in this thread somewhere but can be informative to show it again (if anyone is interested). It is from my V70 BiFuel 2006 Denso ECU with CEM-L. Sync data between CEM and Denso ECU. In CEM eeprom data is in duplicate with crc, in...

Thanks to this https://www.matthewsvolvosite.com/forums/viewtopic.php?p=657191 I have managed to do next small step with my V70 2006. I only have one key. So, first trying to follow what mikeak2001 do in his thread. First step i need to do, enter security access. What key is needed here? It say it i...
