Fuel-It! Bluetooth Flex Fuel Kit

The Burger Motorsports Fuel-It! Bluetooth Flex Fuel Kit is designed for Audi RS3 (8V/8Y) and TT RS (8S) vehicles equipped with the 2.5T engine, allowing for real-time monitoring of ethanol content when running E85 or other ethanol mixes. This complete, plug-and-play kit installs in approximately 15 minutes and includes a Genuine Continental® ethanol sensor, upgraded fuel lines with nylon sheathing, Fuel-It! proprietary billet fittings, a Bluetooth analyzer with a free app for both Android and iOS, and a plug-and-play harness. The kit offers flexible output options, including Bluetooth App connectivity, a 5v analog output, and native frequency output compatible with JB4 and ECU flash tuning. This enables precise fuel mixture adjustments for optimal performance. Compatibility is specified for 2017+ Audi TT RS and 2017+ Audi RS3 models. However, European versions of the RS3 8Y and TTRS platforms are not compatible without modifications, including re-using the stock connector in place of the supplied elbow connection. The "Also fits: Audi RS3 (8V)" note indicates compatibility with earlier 8V models. For users of the Audi JB4 platform, the white wire should be connected to position #16 on the JB4 25-pin harness, and Option 1 for the WMI Ethanol Setup must be selected to enable the pin location 15/16 flex fuel input. Replacement fuel lines are available separately.
