## What is DSFlex ECA?

DSFlex ECA is the official companion app for the DSFlex Ethanol Content Analyzer — 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 — 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).
