Fuel-It! ECA Customer Insights

1. At least that works.In the calculator, there needs to be an option for fuel level % instead of gallons of fuel in the tank.Every time I press the connect button it tells me I need a firmware update.

2. No progress update or status indicator in the app saying it's updating.Does what I need it to, has been 100% accurate with the content sensor.

3. Do yourself a favor and get an actual gauge; don't let your car be tied to someone else's app that's tracking your GPS location.Purchased this setup in January of 2022, I installed in the summer and got it to work twice then dead.

4. Any help would be appreciatedPRETTY GOOD APP.. just one issue under settings: tank side field doesn't allow periods or commas.

5. Super easy to use and eastly to connect up to the BT sensor.Great app and works as advertised.

6. Not to mention that you STILL can't put in a decimal point for the tank size, you've got a rude message about support that pops up, and over all just comes off as an unfriendly developer.

7. But it assumes your gasoline is E0 with no way to change it, so the mix ratio math is always wrong with E10 gasoline.Was not able to get it to connect.

8. I am unable to type 12.4 only whole number.I can't seem to get the app to even find my Bluetooth dongle rendering this app completely useless to me.

9. Saying i need to allow location which is already enabled.

10. Forces you to enable GPS tracking to read data from your sensor.

11. Here we are getting the car back out and sensor doesn't work again.
