Economy and performance

With the help of eFlexPlus, you can fine-tune your engine running on ethanol fuel. You can change the fuel mixture at different RPM levels to improve engine performance and economy. Take the full advantage of the minor performance changes made to your engine.

eFlexTuner-control application

With the eFlexTuner control application, you can modify your eFlexPlus hardware settings in real-time via Bluetooth. The control application runs on computers running Windows 10.

Adjusting the cold start

By adjusting the cold start parameters, you can also optimize engine start-up even in extreme cold conditions. You can influence every step of the engine startup by changing the amount and duration of fuel enrichment. Adjusting the cold start parameters is optional, as the eFlexPlus hardware is also ready to use with pre-tested factory settings.

Adjusting the fuel mixture

Adjustments are made using the eFlexTuner control application. The fuel maps of the eFlexPlus device allow you to accurately change the fuel supply of your engine to your desired RPM levels and to change the enrichment according to the ethanol content of the fuel. The current engine operating point is displayed in real-time on the application map, so adjustment is quick and accurate.


You can save the eFlexPlus hardware operating parameters to a log file while running with the eFlexTuner control application. The collected log can be viewed afterwards. For example, monitor the injector duty cycle based on RPM levels and driving conditions, and quickly identify areas that require fine-tuning.

Extended warranty period

We offer an extended three-year warranty on the eFlexPlus device. Our free product support is also available to assist you in any situation.
