Fuel-It! ECA

It has stopped working and nothing can make it connect again… the installation was checked

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.

Sliders a bit difficult to get correct. Also perhaps a bug. I've gotten mix values that were way off on the calculation page. I have the sensor installed so it reads the current mix. Turns out I have to zero that slider and manually set the current mix to get the rest of the values to calculate correctly. Should be an easy fix

You used to be able to set the app to “allow to keep screen on” so that you could bring up the app and use it like a gauge and the screen on your phone would never turn off. This was helpful when mixing content or waiting for the fuel content to update. Now I have to keep waking up my phone screen. Very annoying. Can we have this option back please???

The calculator when you are using blended fuel (e.g. e30, e50,etc.) isn’t super accurate. Plenty of other options online, but ideally would of been better to have and accurate calculator on this app. They also eliminated the option for the Lock Screen option while the app is open. That was convenient whenever to had to swap between regular premium (e10) and e30 blend. The price you pay for the app is just for the convenience of not having to route wires through the firewall to a gage. Hopefully they address some of these issues on a future update.

Installed e85 flex-it kit on 2019 Mustang GT. I live in FL and test the e85 content of fuel at the pump using e85 test tube. I consistently get e85-e87 content reading from test tube. The flex-it kit is reading e75 - e77 from app. If the sensor is not reading actual ethanol content, what calculation is being used and is there a conversion? Test tube does not lie.

Works as advertised and the new updates were much needed!

Please bring back the option for auto Lock Screen. I use it as a gauge and now my phone locks after a certain time. I don’t want to do it for the whole phone and just for that app. Thank you
