rusefi*.ini files are generated based on the following four inputs:

1. rusefi_config.txt contains configuration region definition in proprietary text format.
2. rusefi.input contains the UI - all the menus and dialogs. UI definition starts at menuDialog = main line - here you will see all top level menus defined with internal IDs and visible text labels.
3. mapping.yaml is a minor detail related to how pins are named in drop downs
4. prepend.txt is a minor detail which allows you to hide elements of the UI using @@if_XXX syntax.

rusefi.ini file is generated by ConfigDefinition.jar tool. On Windows you simply invoke gen_config.bat
