Ignition could possibly be converted to a 'Max advance' setting, but fuel/air ratio is next to impossible unless you can provide a full load map, which is going to be too complex for most people.
If you just specify a single a/f ratio, is that the one that's meant to apply to hard acceleration, highway cruising, idle? What about when on boost vs off boost? WOT vs half throttle? The concept of giving an abstract 'general mixture' figure isn't perfect, but it gets across the intent OK without the need to provide a full map.
