  • It’s very expensive app / no partial refund for one month use.

    By Awgd8
    Make sure you are dead set on keeping your JB4 kit since this app is none refundable once you buy it. You won’t be able to transfer it to another user like your friend also. So If you decided to sell your new JB4 tuner kit, count this app cost as your extra loss.
  • Great app and a must have with the JB4

    By Jay Tolentino
    App is freakn awesome! So much easier to work with a phone than a laptop. Please change the background color as it’s too dark to read and if gauge selections can be adjustable from 1 to 6 gauges this would make it even friendlier to use.
  • Essential app

    By RodCollier
    Great app for the BCS JB4 users, but please drop the blue font with black background... its nearly impossible to see
  • Not working properly screen upside down and backwards can't read anything

    I just bought this app I can't read anything it's all backwards upside down can I get some help please?
  • Incredible Support

    By FallbrookMac
    First of all, having Bluetooth connectivity for the JB4 has been a valuable enhancement. When I had a problem with the BT hardware, I sent the unit to Donnie and after a few email exchanges, he fixed the problem and sent me a replacement unit. The app quality is outstanding and support all the more so. It is amazing that there is such an outstanding product for a niche application. Just get it! If you already made the plunge to get a JB4, the Bluetooth interface will greatly enhance your investment.
  • Username/password server fails

    By snarf`
    The app was GREAT until the username/password was implemented. Now I can't use my iPhone turned iPod for sole purpose of using it to connect to JB4 unit. Remove the username/password and this app will gain back its 5 star rating.
  • Country Check for Passive Delete?

    No thanks.
  • Awesome

    It's money well spent!
  • Great tool

    By Sanchezable
    Love using the app. Updates I hope to see. A gauge for fuel economy (miles per gallon). Add more of the steering wheel controls in the app for easier control. Also a eco map to maximize fuel economy, similar to eco and sport on modern BMWs.
  • App needs updating

    By msafar95
    This app needs an overhaul from top to bottom. The UI is very unfriendly. For the price of the app, it'd be nice fnthe developers atleast made the app look good
