Up to 20% Increase in Performance
Your Fuel System Verified+ Why to use Ethanol fuel?
- Bioethanol (often E85 blend) is the lowest cost fuel available in the market.
- You are driving with locally produced vegetable based fuel. Your carbon footprint goes down by up to 80%.
- You can increase your vehicle’s horse power up to 20% due to the high octane rating of ethanol fuel
+ How do you know my vehicle is compatible?
We always ensure that your vehicle is compatible with the eFlexFuel system. In addition, we check that the vehicle's components, such as the fuel pump, injectors and fuel lines, are resistant to E85.
+ Where the more power and torque comes from?
- Automatic engine tune adjustment optimizes the engine in real-time to match the fuel blend.
- E85 has 100+ octanes that supports higher compression ratios and greater ignition advance.
- E85 contains a great deal of oxygen for burning: the fuel burns more completely producing more power, less harmful emissions and a cooler engine.
- eFlexPro with its fully customizable fuel maps enables precision engine tuning on E85 resulting in up to 20% horsepower gains.
DIY 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.
Supercar Technology in your Daily Driver (or Weekend Warrior)
By installing the eFlexFuel kit, you're in good company. eFlexFuel conversion kits utilize technology found in the Koenigsegg Jesko, Dodge Challenger SRT Demon 170, and other top-tier performance vehicles. This tech is used to get the most out of ethanol, gasoline, or whatever blend of the two you have in your tank.

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.
