    Every time I press the connect button it tells me I need a firmware update. I select yes but nothing seems to happen. No progress update or status indicator in the app saying it's updating.
  • Great App! You need this! Jun 14, 2018

    By Model3Performance
    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.

    Overall this is a good app and does what it’s supposed to do. It does take a minute or two of driving for reading to adjust after fueling up. The calculator needs GUI update to make the slider more user friendly. Can’t enter correct amount of gas tank capacity at 13.7 gallons and doesn’t account for gas already containing some level of ethanol.

    Nice, clean app. I like the sliders on the mixing page. But it assumes your gasoline is E0 with no way to change it, so the mix ratio math is always wrong with E10 gasoline.

    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.

    Does what I need it to, has been 100% accurate with the content sensor. No problems here. Super easy to use and eastly to connect up to the BT sensor.
  • NICE IMPROVEMENT, AND ADDED CALCULATOR Jul 4, 2020

    By Stealth GreyRS
    I like the addition of the calculator, but I have a tough time moving the slides. Also it would be great if it was in percentages to match the Cobb Accessport. Also if the fuel level can be reading actual levels, and the mixture ratios could change along with the tank level.

    Great app and works as advertised. Compared readout with standard test and results were +/- 1 percent. Excellent failsafe to avoid grenading an engine. Highly recommend

    PRETTY GOOD APP.. just one issue under settings: tank side field doesn't allow periods or commas. Please fix 😢. I am unable to type 12.4 only whole number.

    This is seriously awesome. Super way install - highly recommend. I have it 4 stars because it’s lacking item, the Ethanol mix calculator assumed your “E85” is actually 85% ethanol- this isn’t always true. My local is 70% ethanol- so I have to mix more than what the calculator says. If you added a default index, of some sort where the ethanol content could be changed - and also adjust for the fact that most pump gas 91/93 octane have up to 10% ethanol already. Otherwise - great product

    Was not able to get it to connect. Saying i need to allow location which is already enabled. I have a android phone. Any help would be appreciated
  • App needs work Sep 5, 2020

    By Zzaaiinn
    The sliders on the ethanol mixing screen are very hard to use. Placing your figure on the green triangle of the slider doesn’t make it move like it should. Sometimes making the app switch screens because the triangle is too close to the edge of the screen it thinks your telling it to switch screens. If the app developers used the app one time they would know this.

  • Great App! Jun 27, 2018

    By VirtualRonin
    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.
  • Jun 13, 2020

    Works good. Would be 5 stars if ethanol calculator allowed you to account for 10% ethanol content in normal gas.

    I can't seem to get the app to even find my Bluetooth dongle rendering this app completely useless to me. Seeking a refund if possible.
