Unlock the full potential of your BMW F/G Series or Toyota Supra A90/A91 with the ProTuning Freaks Bootmod3 Flex Fuel Kit. Specially engineered for the S55, S58, B48, B58, and N55 engines, this kit provides a seamless, plug-and-play solution for running ethanol (E85) fuel blends, empowering your vehicle with greater performance flexibility. Designed for easy, at-home installation, it brings a high-performance flex-fuel setup directly to your driveway with minimal effort and maximum results. Seamless, Plug-and-Play Installation Our Bootmod3 Flex Fuel Kit was crafted with simplicity and convenience in mind, requiring no cutting or splicing of OEM wiring. The 100% plug-and-play design means you can complete installation in minutes using factory vehicle harness connections. This fully reversible kit allows you to return your car to stock easily and without any visible traces, which is ideal for lease or resale. Precision Engineered for Optimal Fuel Flow Each component of the Bootmod3 Flex Fuel Kit is designed using SolidWorks software for maximum precision and performance. The Flow Optimized Flex Fuel Sensor Adapter (FFSA) ensures that fuel flow is smooth and unobstructed, even at full pump output. Unlike other kits, this design prevents pressure drops, crucial for supporting the enhanced power and high flow rates that ethanol fuels demand. Our custom 3-piece Aluminum-6061 sensor adapter includes built-in bypasses, maintaining consistent fuel delivery from tank to engine for a fully optimized experience. Key Features Ethanol Content Analyzer (CANBUS Enabled): The kit includes a CANBUS-compatible Ethanol Content Analyzer (ECA) that integrates directly with Bootmod3’s CustomROM, providing real-time ethanol content readings to your vehicle's ECU. This compatibility allows seamless tuning with Bootmod3’s Flex Fuel-enabled OTS MultiMaps and custom tunes by your preferred Bootmod3 tuner. Factory Fuel Hat Integration: The Flex Fuel Sensor is designed to fit neatly within the BMW factory fuel hat location under the rear seat, preserving a clean, factory-like appearance and preventing the need for external modifications. Auxiliary Fuel Pressure Sensor Ports: For vehicles without an OEM fuel pressure sensor, the adapter includes two 1/8 NPT ports for easy installation of an additional pressure sensor. This compatibility supports advanced tuning setups with Bootmod3’s CustomROM v2, further optimizing your performance build. Durable Construction: Built with fuel-safe Viton o-rings and a kink-free Teflon braided line, this kit is designed to withstand the rigors of high ethanol content. The custom Aluminum-6061 CANBus enclosure and Racetronix -6 AN fitting ensure both durability and easy installation. Efficiency and Time Savings The Bootmod3 Flex Fuel Kit offers significant time and cost savings compared to other flex-fuel setups. With no need for a shop lift or complex custom fuel line fabrication, this kit saves approximately 4+ hours of labor, allowing you to transition to flex fuel quickly and affordably. Full Compatibility and Reversibility Our kit is designed to be compatible with the BMW S55, S58, B48, B58, and N55 engines across various F and G Series models, as well as the Toyota Supra A90/A91. With a fully reversible installation, you can remove the kit without leaving any traces, restoring your vehicle to its original condition within minutes. Specifications Plug-and-Play Harness: Designed for easy installation to the BMW Fuel Controller (EKP3) connectors on S55 and N55 engines, and to the Body Domain Controller (BDC/FEM) on Gen1 F-series B48/B58 engines.
