Increase power and torque

With eFlexPro you can get up to 15% more power and torque from the engine with ethanol fuel. More than 104 octane fuel is particularly useful for supercharged engines.

Connect to the engine sensors

You can connect the eFlexPro Controller to two motor sensors, eg. MAP, MAF, TPS or WBO (Retrofit Broadband Lambda Sensor). With the help of these sensors, the eFlexPro system measures the engine load level, which can be used to help adjust the fuel mixture.

eFlexTuner-control application

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

Adjusting the fuel mixture

Adjustments are made using the eFlexTuner control application. The fuel maps of the eFlexPro 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.

Logging

You can save the eFlexPro 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.

Optimized engine

The eFlexPro is the best option if you want more power and torque from the engine. The ethanol fuel optimized engine has improved lower torque and pulls efficiently throughout the rev range. A better driving experience and faster lap times await you!
