About

DSFlex ECA

Read full description

DSFlex ECA is the official companion app for the DSFlex Ethanol Content Analyzer β€” a precision Bluetooth sensor that measures the real ethanol content and temperature of the fuel in your tank. Built for flex fuel tunes, E85 conversions, and anyone running a blend of gasoline and ethanol, DSFlex ECA gives you accurate, real-time readings so you can tune with confidence. FEATURES - Live ethanol content (%) and fuel temperature, streamed over Bluetooth from your DSFlex sensor. - Blend Calculator with two modes β€” Target Mix (hit a specific ethanol blend without topping off) and Fill Tank (top off completely using two fuels). - Customizable units β€” Fahrenheit or Celsius, liters or gallons. - Set your local pump gas ethanol percentage and default tank size for accurate calculations. - Clean, simple interface built for quick glances while working on your vehicle. DSFlex ECA is a measurement and information tool. It does not tune your engine or control any vehicle system β€” it gives you the accurate data you need to make your own tuning decisions. Requires a DSFlex Ethanol Content Analyzer sensor (sold separately).
