FEATURES - Live ethanol content (%) and fuel temperature, streamed over Bluetooth from your DSFlex sensor. - Blend Calculator with two modes — Target Mix (hit a specific ethanol blend without topping off) and Fill Tank (top off completely using two fuels). - Customizable units — 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 — it gives you the accurate data you need to make your own tuning decisions. Requires a DSFlex Ethanol Content Analyzer sensor (sold separately).
