  • Mixing ratio calculator included
  • Can be used without the sensor kit

Comments on Fuel-It! ECA for Android

★★★★☆ James Page · Sep 19, 2025
I like the app, but I wish it had an option to keep phone screen on. Also, I wish it didn't round to whole numbers, I like seeing the decimal point
★★★★★ Adam Matthew · Nov 18, 2020
Great app and works as advertised. Compared readout with standard test and results were +/- 1 percent. Excellent failsafe to avoid grenadine an engine. Highly recommend
★★★★☆ Jorge Juarez · Sep 11, 2023
Can you please add settings to adjust the startup? I believe it can help avoid lean codes
★★★★★ Eric Torres · Nov 5, 2019
Does what I need it to, has been 100% accurate with the content sensor. No problems here. Super easy to use and eastly to connect up to the BT sensor.
★★☆☆☆ frederick paul · Nov 29, 2021
Was not able to get it to connect. Saying I need to allow location which is already enabled. I have an android phone. Any help would be appreciated
★★☆☆☆ Loren Ritchey · Nov 14, 2021
For the cost of the kit you would think the app would be free! Every time I open the app and connect ...it tells me I need to update it, I click yes update, and it says the same thing next time I connect. I'm disappointed in this whole experience. 😕
★☆☆☆☆ Nicolas DeMartinis · Jul 6, 2022
Used to work 50% of the time. Now I can't get anything to work. Doesn't matter what is connected to my phone, and it has gps location.
★☆☆☆☆ David Quinones · Apr 23, 2023
Purchased this setup in January 2022, I installed in the summer and got it to work twice then dead. Help team has me send it back to say nothing wrong in November. Here we are getting the car back out and sensor doesn't work again. Now I'm out of warranty and a bit upset. What a waste, just go buy the innovate ethonal gauge. At least that works.
★★☆☆☆ Jaz V · Feb 15, 2026
My positive wire was damaged and support was nice enough to replace my Bluetooth analyzer and connector wire as well under warranty. But after installing in the same location as before it will not connect to my phone or app. I've tried other locations on the car and still won't connect.
