Ethanol Content Analyzer Sensor

The DIYAutoTune Flex Fuel Sensor is engineered to provide critical real-time data for advanced engine tuning, particularly for vehicles running E85 and other ethanol blends. By accurately measuring both ethanol content (0-100%) and fuel temperature (-40°F to 257°F / -40°C to 125°C), this sensor allows your engine management system to dynamically adjust fuel delivery and ignition timing for optimal performance and engine safety. This is crucial for overcoming the variability found in pump E85 and similar fuels, ensuring consistent and reliable engine operation. This sensor features a compact, corrosion-resistant design, making it suitable for the demanding environments found in engine bays. It is available with either a pre-wired 6-inch pigtail for quick installation or as a connector housing with crimp-on terminals and seals for custom harness applications. This flexibility ensures it can be integrated into various setups. The DIYAutoTune Flex Fuel Sensor is compatible with a range of popular engine management systems, including MS3Pro, MSPNP-Pro, MSPNP Gen 2, and MegaSquirt 2 and 3. Proper integration and configuration with these ECUs are necessary for the sensor to provide its full benefits.
