Greetings
I didn't find any existing program to read/write the 24c04 immo eeprom of the EDC15P+ through K-line (with a dumb KKL cable). Therefore I wrote a program that can read and write the contents of the immo eeprom in boot mode. I got the idea from ArgDub's great ME7_95040 EEPROM programmer. Just use a normal dumb KKL cable and start the ECU in boot mode.
Download the program here (.NET framework 4 required):
https://bitbucket.org/JohnJocke/edc15p_immo_flasher/downloads/EDC15P_Immo_flasher_2014_05_13_v1.0.zipI tested the program with EDC15P+. Dunno if it works with other EDC15 variants.
