Elbe Engineering EFI conversion kit (EFI)

Never-Installed EFI Conversion for Mercedes-Benz M116/M117 K/KE Jetronic Engines

The Elbe Engineering EFI Conversion Kit is designed for enthusiasts, restorers, and performance tuners seeking modern fuel injection technology for classic and performance engines. This kit allows for a direct conversion from carbureted systems to electronic fuel injection (EFI), improving throttle response, fuel efficiency, and overall engine reliability.

This EFI system replaces the traditional distributor with a modern electronic ignition setup and integrates an included ECU for precise control. Benefits include improved ignition performance, increased fuel efficiency, smoother operation, and more accurate fuel metering. Bluetooth connectivity allows data monitoring via Android devices, simplifying tuning and diagnostics. No irreversible modifications are necessary, preserving the option to return to the factory system.
