Thank you for help.
K line with dice.
Did I connect something wrong? Will someone suggest?

This is correct:

This commercial tools are based on work from this open forum. Isn't it strange all tools came on marked shortly after this project was visible here. Now you blame us that we don't develop so fast like the guys which get 4600 $ about their full set. I think VTL and I did this just for our own cars, w...

Sorry was 50 downloads only, here are both again...

Also Windows 10 doesn't notice me about anything, maybe it is location based on 3 computers i get nothing. Maybe defender in US sees something problematic in this code...

This works on all CEMs to MY 2004, 10th place of VIN Y, 1, 2, 3 or 4. Read cem by arduino once, place it back into car and change how often you like by dice. screenshot.2 CEM tool.jpg Read CEM by arduino nano or UNO by this: #define BKPT 4 #define RESET 5 #define FREEZE 6 #define DSI 7 #define DSO 8...

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...
