If you want a true electronic governor, they are available. We have lots of aerial equipment equipped with them. Contact Precision Governors and they can help you out. They aren't inexpensive, but used ones occasionally show up on the auction sites. Hoof governors do work, but they're best suited for applications where the engine load isn't varying widely all the time. The Precision Governors use a control module/box that senses engine rpm and sends an output to a throttle control to maintain a set speed. Depending on the governor model, two or three speed "sets" can be programmed in. If you have the "mid speed" trimpot set for 1800 rpm for example, the module and throttle control will maintain that rpm. There are also trimpots for adjusting parameters like gain, so that a controller can be fine-tuned for different applications...since engine response to throttle inputs can vary widely from one application to another. Undershooting or overshooting can be virtually eliminated.
Speed settings, starter lockout settings, overspeed shutdown settings, etc are all dialed in with trimpots on the back of the governor box. No laptop interface required. Speed settings are input to the governor box during operation with a simple switch or relay. If the engine is idling, you flip a switch and the engine immediately comes up to the dialed-in rpm setting. Flipping another switch brings the engine speed up to the next dialed-in speed setting. One big advantage to the inputs being electrically switched is that remotely mounted engines don't need to have a convoluted throttle linkage or cable run from the operator station to the engine.

The models we have the most of are the E-331 and E-301 governors. In addition to aerial equipment, they're found in gensets, floor and street sweepers, etc.
