Overview

The Eflex Fuel SK1100US is an E85 flex fuel conversion kit designed for specific vehicles. This kit allows your vehicle to run on E85, gasoline, or any mixture of the two automatically, without requiring any tuning or map changes.

The kit includes everything needed for DIY installation and operation on E85. It aims to make more power, lower operating temperatures, and reduce emissions. The system automatically adjusts fueling based on the ethanol content in the tank and will not trigger a Check Engine Light. It also features Bluetooth 5.2 and a shock-proof, weatherproof IP68 casing.
Show original supplier description
The eFlexFuel eFlexPlus E85 Flex Fuel Conversion Kit offers a fully automatic solution for running your vehicle on E85, gasoline, or any combination. This system utilizes an ECU that pairs with a smartphone app, providing control over performance modes such as Economy, Sport, and Dynamic. Designed for plug-and-play installation, the kit requires minimal modifications and is estimated to take approximately 3 hours to install. However, it necessitates mechanical expertise or professional installation. The kit includes a control unit, ethanol sensor, a vehicle-specific wiring harness with an external temperature sensor, cable ties, male fuel injector connectors, fuel hose, fuel line quick connectors, a fuel line disconnect tool, and hose clamps, along with an installation and user guide. This eFlexPlus kit is specifically suitable for 2021-2026 Jeep Wrangler JL Rubicon 392s, 2008-2023 V8 HEMI Challengers, 2020-2026 7.3L F-250 Super Dutys, and 2006-2023 V8 HEMI Chargers.
