Diesel EFI

> What is (are) the correct A/F (or O2/F) ratios for diesel engines of this type?

You've got it easy. Diesel engines don't really care about an A/F ratio. You
just put in all the air you can (most normally aspirated diesels don't even
have a throttle), and add as much diesel fuel as needed to produce the amount
of power needed. The A/F ratio is not important, only the amount of fuel
and the power desired.

Given this, you'll see that a two bit governor which adds more fuel as the
engine speed drops, and less as it overspeeds, is sufficient for most fixed
speed applications. Naturally you'll want to use a micro, and a whole bunch
of sensors, but you can build a perfectly good mechanical system for a lot
less.
