Comments on eFlexApp for Android

★★★★☆ Ppc C. · Apr 18, 2023

Please bring back landscape mode. Also, it asks for access to location, I thought it would have a speedometer next to the tach. That would be a huge plus.

★★★★☆ Pedro Maya · Mar 23, 2022

I like how I have my options to select start up and monitor my ethanol sensor percentage very neat simple easy to use. Sometimes it has a hard time connecting but otherwise the reflex plus is a great device and during this war with Russia and Ukraine I know has price will go up and e85 is still really low.

★★★★☆ Brian Cassidy · Jan 23, 2026

This company is the best for installing E85 to your vehicle. The app is great, I wish they would do more updates to the app to change it up every now and then. Other than that it works great. Have had no issues since I installed it on my 2010 Camaro SS. I definitely recommend this company for installing E85 to any vehicle you have. Love that you can run any mixture of fuel in it as well. Keep up the good work Reflex Fuel

★☆☆☆☆ Ossi Pärssinen · Aug 8, 2021

Initially worked. Now it says "you must connect to device named eflexfuel". In the list it shows device named Flex Fuel and does not want to connect.

★☆☆☆☆ Moises Recancoj · Oct 11, 2023

The app doesn't work properly. I have to Uninstall/ reinstall and then works. Whe I reinstall it works one time. So depressing.
