Adjust your engine performance

Precision tuning starts with eFlexTuner

The power is in your hands with our intuitive eFlexTuner software. The adjustments that you make will affect the engine’s fuel mixture in real time, so it’s easy to monitor the results. Adjustments can be performed on a dyno or during normal driving.

eFlexTuner can be downloaded for free and is compatible with eFlexFuel Plus and Pro devices. The software is developed inhouse by the eFlexFuel R&D team.

eFlexTuner requires Windows 10/11 OS, as well as Bluetooth 4.0 support. BT Dongles can also be applied.

Fuel map adjustment

eFlexTuner supports engine RPM and engine load-based fuel map. In load-based maps, a sensor of your choice (e.g., MAP, MAF, TPS) is used when adjusting the injection. The used fuel map cell is displayed in real time which, thus, simplifies the adjustment process. Tune in real time or make adjustments offline based on log files.

Log file analysis

eFlexPro and eFlexMoto Pro log files can be analyzed in depth with the eFlexTuner. Data can be taken from an entire session or a specific timespan. The data is color-coded, which helps to distinguish e.g., the fuel mixture or the injector duty cycle.

3D fuel maps

Fuel maps can be observed in the 3D graphics window. The view can be rotated freely, and selected fuel map cells are highlighted over the 3D map. The color-coded fuel map makes analysis simple.

Sensor linkage

Two external sensors can be connected to the eFlexPro or eFlexMoto Pro control units with sensor files created in the sensor editor that can be linked.

Cold start adjustment

Utilize our versatile adjustments for cold starting. You can define your settings in three different phases of start-up from cranking to warm-up. Monitor the cold start process in real time.

Fault codes

eFlexFuel products have built-in self-diagnostics. With eFlexTuner, you can read the fault codes and troubleshoot the possible cause.

Data logging

All running parameters of the control unit can be captured and saved to a log file. Choose which parameters are displayed on the log screen
