The PRL Motorsports Plug ‘n Play WiFi Flex-Fuel / Ethanol Content Analyzer Kit is engineered to enhance the performance of your 2016-2021 Honda Civic 1.5T. This innovative system enables you to wirelessly monitor your vehicle's ethanol content through any smart device. Alternatively, it offers a configurable 0.5V - 4.5V output, allowing seamless integration with tuning devices and dataloggers for advanced flex-fuel capabilities. It connects to existing factory plugs under the hood, eliminating the need for complex wiring, cutting, splicing, or routing cables through the firewall. All required hardware and mounting brackets are included, ensuring a quick and straightforward installation process that can be completed in minutes. The kit components are fully compliant with ethanol fuels. This kit is compatible with all 2016-2021 Honda Civic 1.5T models, including Si, CVT, 6MT, RHD, and International variants. However, it is explicitly NOT compatible with PRL PTFE Fuel Lines. The system integrates well with popular tuning platforms like Hondata and KTuner, which can display the ethanol content data. While the factory fuel line is robust and resistant to ethanol-based fuels, it's crucial to avoid kinking it. The kit includes a billet aluminum converter case with a sealed and potted WiFi board, a genuine GM Continental Ethanol Content Sensor, billet stock location EFI diverter fittings, and a plug-n-play braided wiring harness. Please note that this product is not legal for sale or use in California on any emission-controlled motor vehicle.
