Show original supplier description
The PRL Motorsports Flex Fuel Kit provides a comprehensive solution for 2016-2021 Honda Civic 1.5T enthusiasts looking to utilize ethanol-based fuels. By wirelessly monitoring ethanol content via a smart device, or integrating with a tuning device through a configurable 0.5V-4.5V output, this kit enables the vehicle's ECU to perform real-time fuel mixture adjustments. Its patent-pending design integrates directly with the factory fuel line, eliminating the need to replace existing lines while improving under-hood aesthetics. Technically, the kit consists of a billet aluminum converter case with a sealed and potted WiFi board, a genuine GM Continental ethanol content sensor, and billet EFI diverter fittings. The installation is streamlined for a plug-and-play experience, utilizing factory plugs and outputs under the hood to ensure power and communication without the need for wire splicing, cutting, or firewall routing. Please note this kit is NOT compatible with PRL PTFE fuel lines. Additionally, it is not legal for sale or use in California on any emission-controlled motor vehicle. Proper installation should be performed by a qualified mechanic or fabricator, as some products are intended for high-performance applications.
