Boost Performance with the eFlexMoto Plus E85 Flex Fuel Conversion Kit
Install eFlexMoto Plus, fill up with E85, and drive — it’s that simple. Unlocking the performance benefits of E85 has never been easier or safer:
- Run on E85, gasoline, or any blend — automatically
- Fully automatic operation: no tuning, map switching, or manual adjustments required
- Choose Eco, Dynamic, or Sport driving modes, adjust cold-start fueling, monitor ethanol content and injector duty cycle — all via your smartphone with the eFlexApp
- Clean installation that doesn’t interfere with your factory ECU, OBD system, or trigger a check engine light
- Vehicle-specific E85 compatibility verification — including injectors, fuel pump, fuel lines, and any modifications
- Includes everything needed for E85 conversion and DIY installation
- Gain more power, lower engine temperatures, and reduce emissions with E85
The eFlexMoto Plus kit automatically adjusts fueling based on the ethanol blend in your tank, helping eliminate knock and optimize engine performance. It’s the easiest way to convert your vehicle into a true flex-fuel setup—capable of running E85 or gasoline. For those seeking advanced tuning capabilities, we recommend exploring our eFlexMoto Pro kit.

eFlexTuner 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.

Peak power gains do not always tell the whole story! It's important to look at power gains across the entire RPM range / dyno curve, A.K.A. power "under the curve." Power gains under the curve will have a greater impact on driving experience. This is because gains under the curve impact the broader usable powerband, whereas peak power is momentary - only at one point in the RPM range.
If peak gains are 5% while max gains under the curve show 20%, this +20% increase is a better reflection of how your driving experience will change (you'll certainly feel that increase!). You want to feel the difference in the seat of your pants, and this is where power under the curve plays usually the biggest role.
