Convert your vehicle to run E85, gasoline, or any blend of the two with the eFlexPlus Flex Fuel Kit. Installation is simple—install the system, fill up with E85, and drive. The eFlexPlus automatically detects the ethanol content in your fuel and adjusts fueling in real time, allowing your engine to safely maximize the performance benefits of ethanol without requiring ECU tuning.

Designed for simplicity and reliability, the eFlexPlus system installs under the hood without modifying your factory ECU or triggering check engine lights. With real-time monitoring through the eFlexApp smartphone interface, you can track ethanol content, injector duty cycle, and vehicle data while selecting different driving modes to match your driving style.

True Flex Fuel Capability: Run E85, gasoline, or any mixture of the two without manual adjustments.

Fully Automatic Operation: No tuning, ECU flashing, or map switching required. The system automatically adjusts fueling based on ethanol content.

Smartphone App Control: The eFlexApp allows you to monitor ethanol percentage, injector duty cycle, engine RPM, and more while selecting between Eco, Dynamic, and Sport driving modes.

Safe Plug-and-Play Installation: Installs under the hood without touching the factory ECU, OBD system, or triggering check engine lights.

Real-Time Ethanol Monitoring: Ethanol content is measured over 100 times per second to ensure accurate fueling adjustments.

Improved Engine Performance: E85 allows engines to run cooler, reduce knock, and produce more power when compared to traditional gasoline.

Complete DIY Installation Kit: Includes all components required for installation and ethanol conversion.

Vehicle Compatibility Verification: Fuel system components such as injectors, fuel pump, and fuel lines are checked for E85 compatibility before installation.

Once your items are ready to ship, we will send tracking information via email so you can easily follow your package from our warehouse to your door.

Cancellation Policy

If you need to cancel or modify your order, please contact us as soon as possible. We strive to ship your order quickly, and once processing begins, cancellations may be subject to a restocking fee.

Return Policy

Customer satisfaction is our priority, and we are happy to assist with returns. However, due to the complexity of sourcing and delivering our products, returns are subject to a restocking fee (usually 20%) based on the item and manufacturer.
