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...

PMd you a working version but it is very terrible to work with, maybe i will get done a better version i can show to the forum...

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...

You can crack the UDS pin by dice. Then take the UDSreader and read your firmware by dice. In this firmware you find the 6 byte code of your cem at this position: offset _ B3 B1 B5 B0 │ B2 B4 XX XX 04E000 53 38 03 21 │ 18 02 FF FF PIN = B0 B1 B2 B3 B4 B5 PIN is 21 38 18 53 02 03 So you have both pin...

This was thought more as a joke to some members here.I don't know if there really exist some documentation about p2 protocol. Everything i know about P2 protocol is by logging and analyzing. I provide a working example here which i think is more useful to most members here as writing around some stu...

I received my Arduino Nano today in order to run T5Luke's code on my 2004 V70. I have it set up and compiling the code successfully through Arduino IDE. Now I'd appreciate some instructions on what to do next. 1) For wiring power to the ECU, should I use the 5v output on the nano itself? Or would a...

This is how it is in Denso as well, the SH7055 controller splits the can id and ext id between some bytes, but I always assumed they were re-assembled in the can ID we see in the logs with no extra bits or bytes. For instance my bench ECU replies with 0x0080021 for 000FFFFE. And this is what I assu...

So you should buy a used ECM which was build in a car with same engine configuration. MY of donor car should be 2005- . About the automatic gearbox module i'm not 100% certain, it could be yours will work, otherwise just buy another module of a car with same engine type and same MY 2005- , all modul...

ECM you need should be 30668478A 0261208289
some standard Bosch petrol ETM. The rest should stay the same. About the TCM i'm not 100% certain but think it should also stay...
