If someone needs i made a arduino nano soloution to read and write this type of cem by same pins, so no reason to buy further hardware...

Here have fun with it: #define BKPT 4 #define RESET 5 #define FREEZE 6 #define DSI 7 #define DSO 8 static word CMD_READ = 0x1940; static word CMD_GO = 0x0C00; static word CMD_WRITEM = 0x1840; char command; int n_line; void setup() { // put your setup code here, to run once: pinMode(BKPT, OUTPUT); di...

BKPT to D4
RESET to D5
FREEZE to D6
DSI to D7
DSO to D8

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...

Here is parameter file for T5Lukes config editor, will add more probably tommorow if i have the time.

I can check in a few hours

Added amp and trip computer

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...

Thanks all for your help with this. Just posting this, adding to the work that Dudde and T5Luke have been doing so far in mapping the parameters. Not sure if this is entirely correct in places but the majority does seem to match up I think (to my vehicle anyway). Unless the mapping has different val...

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...
