The Z Master® EFI features the newest technology from Kohler engines — closed-loop EFI. This system allows the engine to automatically adapt to load, weather, fuel and altitude changes for faster response time and up to 25% better fuel economy. The Kohler closed-loop system is environmentally friendly, running much cleaner than carbureted models by running at optimal levels.
