  • Update back to 5 stars.

    Edited. Back to 5 stars. Donnie fixed the graphing issues and is back to normal. Anyone that does not like the latest update. Try the revised one on the TestFlight app. You may have to ask for a TestFlight invite. Please revert back to the old version. The update is terrible. Graph graduations are better at 5, graph buttons overlay on phone icons take multiple presses to close graph? Let us scroll to the end of the graphed log, pop up for detailed graph info back to normal as well. All around update makes this app worse. I’d give it 5 stars the way it used to be. Icon legend is harder to read. I’ve emailed you during the test flight version that it was bad.
  • New update is Horrible

  • Why I hate this app

    By i hate jb4
    You can’t connect ever wouldn’t recommend to anyone
  • A must have

    By Osunar
    It’s an amazing app! A must have for Jb4 owners. You can change maps on the fly via Bluetooth, in case you can’t find e85 and have to run on 93 only, it’s a cinch to lower boost a bit so you don’t damage your engine! All the different read outs are very accurate as well!
  • Need to buy Bluetooth wireless connection

    Didnt know i have to buy a addittional 140 dollar Bluetooth connection that i have money for so now im stuck with this app i spent 30 dollars on that im not gonna use
  • Amazing App

    By CntryClub007
    This app is awesome, can change between Methanol Injection and standard all from the phone. Can also log data for tweaking purposes. Clearing codes paid for itself already once. Great piece of kit!
  • Works Great!

    By Greg21040
    It works great, but it’d be better if it worked in Apple CarPlay.
  • JB4 is garbage

    By Rumplelstiltskin
    It’s so nice of Burger Motor Sports to hide the $30 charge for the iPhone application after you spend $150 thinking you’re good to go. And don’t try to update the firmware because that will just ruin your unit.
  • Awesome data logging

    By LaTin..
    Love the real time data logging through your phone via Bluetooth. Makes things a lot easier to monitor. I always have it on whether I’m driving to work, going to the gym, test driving the car etc. Much more convenient than a laptop!
  • Doesn’t connect

    The app does not connect to the jb4, it keep asking to select the type of engine
