Run Gasoline, Ethanol or Anywhere In Between Want the flexibility to run pump gas, E85, or different ethanol blends without being locked into one fuel? The Link ECU Ethanol Content Sensor (ECS) allows a compatible Link ECU to monitor the ethanol percentage of the fuel flowing through your fuel system. When combined with a properly configured flex-fuel calibration, your ECU can use this information to adjust the engine calibration as ethanol content changes. It's an essential component for anyone building a serious flex-fuel street or race car. Know What's Actually in Your Tank Fuel labeled E85 doesn't necessarily contain exactly 85% ethanol. Ethanol concentration can vary depending on the fuel source, location, season, and the amount of gasoline already remaining in your tank. Instead of guessing, the Link ECS gives your ECU real-time ethanol-content information. Your tuner can use that data to build a calibration that responds to the actual fuel in the vehicle. Perfect for Flex-Fuel Tuning With a compatible Link ECU and properly configured calibration, ethanol-content data can be incorporated into strategies for: Fueling Ignition timing Boost targets Cold-start enrichment Engine protection Datalogging Fuel composition monitoring This means you don't necessarily need to completely drain the tank every time you switch between gasoline and ethanol-based fuel. Fill the vehicle with the fuel you want to use, and the ECU can determine the resulting ethanol concentration and apply the appropriate calibration strategy when properly configured. Ideal for Turbocharged & High-Performance Builds Ethanol-based fuels are extremely popular in boosted applications because they can support aggressive performance combinations when the entire fuel system and calibration are properly designed. The Link Ethanol Content Sensor is an excellent addition for: Turbocharged engines Supercharged engines High-compression naturally aspirated engines E85 builds Flex-fuel street cars Drag cars Roll-racing builds Road-race cars Engine swaps Custom standalone ECU installations Real-Time Ethanol Content in Your Link ECU Once installed and configured, ethanol-content information can be monitored and datalogged directly through the engine-management system. This gives both the driver and tuner valuable information about the fuel currently being used. Instead of assuming you have E70, E75, or E85 in the tank, you can actually measure it. Key Features Genuine Link ECU Ethanol Content Sensor (ECS) Measures ethanol concentration in the fuel Designed for flex-fuel applications Compatible with supported Link ECU configurations Provides real-time ethanol-content data Allows ethanol percentage to be datalogged Supports flex-fuel calibration strategies Excellent for gasoline/E85 blended applications Ideal for naturally aspirated and boosted engines Suitable for street and motorsport applications Compact inline fuel-system design Build a Smarter Flex-Fuel Setup A proper flex-fuel system isn't simply about installing larger injectors and filling the tank with E85. The ECU needs to know what fuel is actually in the vehicle. The Link ECU Ethanol Content Sensor (ECS) provides that information so your Link ECU and calibration can respond appropriately as ethanol concentration changes. Whether you're running straight gasoline today, E85 tomorrow, or a mixture somewhere in between, the ECS gives your engine-management system the data needed to know the difference. Stop guessing what's in the tank. Measure it. Tune for it. Important Installation Note The Ethanol Content Sensor must be correctly installed, wired, and configured within a compatible Link ECU system. Fuel-system layout, fittings, wiring, ECU input configuration, and flex-fuel calibration requirements vary by application. For best results, have the sensor installation and flex-fuel strategy configured by an experienced tuner.
