For step 2, you need the MSL from your ECMDroid as well as the MSQ from the current EEPROM. Once you optimize the tables and save the new EEPROM to txt, it will also produce an .epr file. It's the .epr file that you put on your device in the /org.ecmdroid/files/eeprom/ folder. Then in ECMDroid you open the epr file (load eeprom) and burn it to the ECM via bluetooth.
