User Reviews

Overall, Fuel-It! ECA is valued for its UI and hardware integration, but recurring issues with Bluetooth reliability, sliders and blending calculator accuracy, removal of auto lock screen, and stability problems undermine its consistency. Users want more precise input options, a fix for pairing and channel selection, and continued updates to improve reliability.

Pros

Works as advertised and fulfills its core purpose of monitoring ethanol content and guiding mixing.
Quick and reliable Bluetooth connection when it works.
Useful features such as the ethanol blend calculator and fuel temperature display.
Clean GUI with a visually appealing interface.
Beneficial updates and ongoing improvements that add needed functionality.

Cons

Bluetooth connectivity is inconsistent with pairing failures and sometimes forces closes, with no option to change the module channel.
Sliders and input controls are hard to use and basis calculations for blends can be inaccurate, requiring manual adjustments.
Irregular or inaccurate ethanol blending calculations for blended fuels and tank size inputs that restrict decimals.
Auto Lock Screen feature has been removed, requiring users to keep the screen on manually or rely on the phone settings.
App crashes or becomes unstable at times and user support responses appear slow or lacking.

Recent reviews

This app looks decent from a GUI perspective however, connecting to the bluetooth module takes several attempts to connect and sometimes even forces the app to close. Not sure if it’s a frequency issue or the app. Regardless, there are no ways to change what channel the module can be on in order to possibly fix the connectivity problem. I hope this is fixed with newer versions but until then I have to give this 2 stars

Works just as intended

I’m pretty familiar with what my car needs when it’s low, it’s almost always the same amount of e85 and 93 to get a full tank. Sometimes the calculator glitches or is just incorrect and I have to restart app several times for it to act normal.
