Show original supplier description

The Stepone Tech eFlexPlus is a fully automatic flex fuel conversion kit designed to enable vehicles to run on any mixture of E85 and gasoline. By connecting under the hood, the system integrates seamlessly with the factory fuel system, allowing for real-time fueling adjustments that optimize performance without the need for ECU flashing or map switching. The kit is managed through the Bluetooth-enabled eFlexApp for iOS and Android, which provides users with monitoring capabilities for ethanol content, cold start settings, and various driving modes. Installation of the eFlexPlus is a DIY-friendly process that typically takes 2-4 hours, involving the use of provided plug-and-play wiring with quick couplers. Although the system installs parallel to the factory components to preserve OBD functionality and avoid triggering check engine lights, it does require fuel line modification. This kit is intended for standard builds; users with high-horsepower setups featuring upgraded injectors may need to consider the eFlexPro model for custom tuning requirements. Key features include the ability to deliver increased power and lower engine operating temperatures when using E85. Each kit comes with a 5-year warranty upon registration to ensure long-term reliability and support.
