I need a simple module (If there is one) for my experimental helicopter engine.
Each ECU (2) will control 2 cylinders (Firing at the same time) at a constant speed with governor (8,000 rpm hovering, 4,000 rpm cruise) using a 2 speed transmission. Helicopters have to maintain a steady rotor speed.
Unfortunately these GM units look heavy but I can probably shave weight with lighter housing.
Any suggestions on what to use?
I just stumbled on this site which looks promising.


This in essence is similar to a single cylinder lawnmower application.
