Electronic fuel injection for drones
Forget about carburation issues with Lö EFI kit
The first tailored EFI kit
When buying the ECU and the other items separately, it is hard to make the right choices. To prevent mistakes, it is better to get a complete Lö EFI kit
with the adequate components for your engine
Lö EFI kit, light and reliable
Highly configurable, for engine types from 10 to 500 cc: two-stroke, four-stroke, single cylinder, boxer, heavy-fuel and wankel.

Lö ECU, maximum functionality
The Electronic Control Unit of the EFI ensures an optimal engine performance, while keeping its weight to the minimum.
Lö ECU INPUTS
- Crank sensor
- Throttle position (TPS)
- Analog input (gen. purpose or O2 sensor)
- Cylinder head temperature (CHT)
- Manifold temperature (MAT)
Safer than carburetors
Lö EFI is very easy to adjust so that fuel consumption is optimal
The EFI ensures optimum engine performance, lower consumption and adaptability to a wider range of environmental conditions.
