Ratings and Reviews
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.
Well worth the price!
Even if you have the JB4 Mobile app for monitoring your Ethanol percentage, get this app! Especially if you're not running 100% E85. This app has a feature that helps you determine how much E85/Pump fuel to add to hit your target percentage. I used to do the math myself at the pump, but this app is SO much more convenient! Well worth the price.
This is a great app, very nice looking, and works as intended. An added bonus is having fuel temp display as well. Only complaint is that I can only enter whole numbers for my tank size. My tank is 12.4 gallons so the calculator can't be used for accurately mixing E30.
With Family Sharing set up, up to six family members can use this app.
