Description
Fuel-It! Universal Bluetooth Flex-Fuel Analyzer (Ethanol Content Sensor Interface)
Monitor and optimize your fuel system with the Fuel-It! Universal Bluetooth Flex-Fuel Analyzer, a complete plug-and-play solution designed to add real-time ethanol content monitoring to vehicles equipped with compatible Continental-style flex-fuel sensors.
This advanced analyzer connects directly to your ethanol sensor and transmits live ethanol content data via Bluetooth to your smartphone, while simultaneously providing multiple output signals for integration with ECUs, gauges, and data logging systems. Whether you're running pump gas, E85, or custom blends, this system gives you the precise data needed to safely maximize performance.
Engineered for versatility, the Fuel-It! analyzer includes three output types in a single unit: Bluetooth, analog voltage (0–5V and 0.5–4.5V), and raw frequency signal (50–150Hz). This allows seamless compatibility with a wide range of aftermarket tuning platforms and engine management systems.
With its plug-and-play design, the analyzer installs quickly with minimal wiring, making it an ideal solution for enthusiasts and professional builds alike.
