Precision tuning starts with eFlexTuner
The power is in your hands with the intuitive eFlexTuner. After installing the eFlexPlus, eFlexMoto Plus, eFlexPro, or eFlexMoto Pro kits on your vehicle, download our free E85 tuning software to make adjustments to your engine in real-time.
Get more power and torque out of your vehicle even less than an hour or without a dynamometer.
eFlexTuner
Easy preset options to tune your engine for different situations.
Fine-tuneduring normal driving using the logging feature or on a dyno.
Create one custom tune (with eFlexPlus) or three custom tunes (with eFlexPro).
Easily monitor results from the tuning software or the eFlexApp, eFlexFuel Technology's exclusive app you can also download for free
How eFlexTuner Works?
Every modern vehicle has an engine control module (ECM) that monitors the air-fuel mixture so it can be adjusted optimally. When you use tuning software, you are not able to reprogram the ECM to improve your engine's performance. Instead, eFlexFuel is a piggyback system, so you can make tunes that will automatically read and customize - in real time - the ECM’s fueling parameters.
With eFlexTuner, the E85 fuel enrichment can be optimised to be as optimal as possible. Many vehicles, as they wear out or with various tuning components, easily start to change the vehicle's fuel enrichment to be either too lean or too rich when accelerating hard. This may results in loss of power and torque in certain RPM areas because the wrong amount of fuel is being fed to the engine. eFlexTuner allows you to clearly see in real time where these "bad" areas are located and adjust them without touching any of the vehicle's original settings.
This means you can get all the power out of your vehicle in less than an hour or without the need for a dynamometer.
Main Features
3D Fuel Maps
With eFlexFuel's Pro models, 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.
Data Logging
All running parameters of the control unit can be captured and saved to a log file. Choose which parameters to display including date range. eFlexPro and eFlexMoto Pro log files can be analyzed in-depth with the eFlexTuner. Color-coding helps distinguish data points. (For example, the fuel mixture or the injector duty cycle.)
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.

- Virtual Load Sensor Tuning: Easily & safely create custom ethanol fuel maps based on your own vehicle's performance & modifications, without tapping into external load sensors - all from your laptop. Now you can augment your Ethanol fueling yourself, without touching your factory ECU and without jeopardizing engine safety.
- Fuel map adjustment: eFlexTuner supports engine RPM and engine load-based fuel maps. With eFlexPro in load-based maps, a sensor of your choice (e.g., MAP, MAF, TPS, WBO) is used when adjusting the injection. The fuel map cell being used is displayed in real-time which simplifies the adjustment process. You can 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: With eFlexFuel's Pro models, 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 (e.g. MAP, MAF, TPS, WBO) can be connected to the eFlexPro or eFlexMoto Pro control units. Sensor files created in the sensor editor can be linked.
- Cold start adjustment: With the 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 to display including date range. eFlexPro and eFlexMoto Pro log files can be analyzed in-depth with the eFlexTuner. Color-coding helps distinguish data points. (For example, the fuel mixture or the injector duty cycle.)
E85 Tune Technical Details
The eFlexFuel R&D team developed both the eFlexApp and our E85 tuning software in-house so that both meet the specific requirements of our E85 kits. While all eFlexFuel kits come with fully automatic, real-time ethanol content detection sensor,it's only with the eFlexPlus and eFlexPro kits that you can also tune for improved performance.
Other requirements for the eFlexTuner:
Windows 10/11 OS, Bluetooth 4.0+ support (Most laptops have this. USB Bluetooth dongles can be used if the laptop or desktop does not have Bluetooth.).
