Don’t think whoever created app ever used it

On main screen the temp jumps from F to C and there’s a dash or something under it which could be negative. But why would it be if it’s 70° F ambient temperature.

On the mix screen threes no decimal for tank size. Like many have said, the slider is horrible. Just have an input field instead or in addition to.

Leaves much to be desired.

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.

Great App! You need this!

Installed the Fuel-It port injection (pi) system on my 135i with the Bluetooth ethanol analyzer. The system feeds my JB4 directly the E content; but, this app gives you fuel temp and it has a tool to tell you how many gallons of e85 and premium to add to reach your desired E level. It connects flawlessly immediately (easiest Bluetooth app I’ve ever used). Also, it allows you to validate that your JB4 is connected correctly to the pi controller (your JB4 e85 reading should match the Fuel-it app). Love it.
