I built an electronic governor a couple years ago for my MH44 EFI using a late model throttle body. It was a prototype, with some issues, so I never installed it. It used an Arduino micro controller. The two main issues it had were analog resolution (1 out of 255) and the throttle plate was spring closed with a weak spring.
I have ordered a four channel analog to digital converter (1 out of 65535) resolution. I will use two of these channels to look at the throttle lever and two to look at throttle plate position. The reason for two channels each is that allows me to cross check the positions.
I need to find a two channel higher resolution analog out (PWM) converter for the throttle plate. One output will control the throttle plate and the second output will go back to the ECM to emulate the throttle position sensor. I will use a plus/minus bridge circuit so I can drive the throttle open and closed while using the spring as an emergency closed, this should give me much faster close response.
My concern was that the lower resolution will not adequately represent the mechanical governor.

The closest town to ours was only 3 miles away, and there were seven dairy farms in the areas of these two country towns. We had 5 acres, and because my Dad was a salesman and not a dairy farmer, he let the Bockovens, who owned the Willow Tree Dairy farm most of our land.
