eFlexTuner
Adjust the factory settings of your eFlexPlus and eFlexPro control units to tune your engine to your exact specifications

PRECISION TUNING STARTS WITH EFLEXTUNER

The power is in your hands with our intuitive eFlexTuner software. Adjustments you make will be reflected in your engine’s fuel mixture in real time, making for easily monitored results that can be adjusted on a dyno or during normal drive.

The eFlexTuner requires Windows 10 OS or better as well as Bluetooth 4.0 support.

FUEL MAP ADJUSTMENT

Fuel injection can be adjusted with the eFlexTuner. Adjustments are made with a separate fuel map, while engine RPMs and engine load, based on a sensor of your choice (e.g. MAP, MAF or TPS), are used when adjusting the fuel map. When driving, eFlexTuner displays which sector of the fuel map the correction is read, simplifying the adjustment of the enrichment.

FUEL MAP ADJUSTMENT

Fuel maps can be observed in the 3D graphics window. The view can be rotated freely and selected squares are displayed with separate markings. The color-coded fuel map makes analysis simple.

COLD START ENRICHMENT ADJUSTMENT

Utilize our versatile adjustments for cold starting with the eFlexTuner by monitoring the cold start properties in real time on separate start-up tabs.

LOG FILE STORAGE

All running parameters of the control unit can be saved to a log file during engine operation, allowing you to choose which parameters are displayed and stored.

LOG FILE ANALYSIS

eFlexPro 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 the fuel mixture or the injector duty cycle.

SENSOR EDITOR

With the eFlexTuner’s sensor editor, create new EFS files from sensors connected to the eFlexPro control unit. The voltage value of each sensor can be converted into a measurable quantity (MAP sensor = pressure, MAF sensor = air mass, broadband Lambda sensor = fuel mixture) within the files. The sensor editor also supports the voltage variable conversion as interpolation or a curve function.

SENSOR LINKAGE

Two external sensors can be connected to the eFlexPro control unit with sensor files created in the sensor editor that can be linked.
