Easy to use. Fun to use love it especially when the car is cool so much fun you can feel the power. Thank you so much . I'd to mention, though their troubleshooting is email only they helped me with my adapter and replaced it got damaged somehow and I was still under warranty. Thank you so much.
love the app, no problem with the connection like everybody is saying, just use a good device, well what I can say I general yeah it doesnt so all the functions of the steering whell bjt it does have the gauges and you can do data logs, the best what you can get for this price, the best money ever spend on jb4 in general, so glad that I went with it, you guys did a great job, in the near futer going with doc racing single turbo kit, cant wait to put out a serious power numbers
Took the JB4 off the car for a few days, reinstalled the kit and the app updated itself. Now it tells me to update firmware, fail every time, stuck at "Flashing..." then gets error: DFU DEVICE DISCONNECTED. Please help UPDATE: Clicking "Cancel" on the firmware update 3 times, then click "OK" to confirm, update succeeded. I guess the Bluetooth kit had to be waken up for the flashing or something like that.
Been using the JB4 and JB4 Mobile since the early days, it's amazing feature that provides monitoring, logging and adjustments in easy user friendly interface, the support of the team always exceed the expectations and they go above and beyond to make sure everything works perfectly, it's an amazing product with exceptional true after sales and support. Highly recommend them without hesitating đź‘Ś đź‘Ť
Note for newbies: if you're using the bluetooth kit to connect, you have to initiate the bluetooth connection from the app and not from the android system settings like every other bluetooth device you would use. It's pretty silly that it requires you to connect this way, but that's how it works.
Although I love the improvements the JB4 does to my car, unfortunately the app requires a lot of work. The inability for them to show gauges on Android Auto is blamed on Google, but given that Torque Pro can do it, I'm not convinced they've really tried. The fact that they don't support AIBoxes and with no indication that they ever will (had to find this out from support) is really disappointing.
What can I say, this app is a big fat RIP OFF!! Seems to be missing a bunch of things I would of expected as standard (like everything you can change from the steering wheel for starters), seriously needs a screen for setting all the configurations and vehicle gauges. I also find it ludicrous you have to pay for the app after paying $150 for the wireless dongle....
This app makes data logging and making adjustments extremely easy. The ability to view active readings of basically any 6 pieces of data on the car you want is great as well. Customer service helped me work through a connection problem that I was having to my tablet and was very pleasant to work with. Even though I have the free software for data logging on my computer to have it so easily available with a tablet is awesome. I’d definitely spend the money on it again!
Logging is.. more or less bulletproof now. But, there are no updates to the values after the first pass of each group in built in graph viewer. Seems to make least one new file after midnight. Restarting app helps a little but after enough times it will not connect to the jb4 unit. Maps have no descriptions so it's anyone's guess what settings are being applied when I pick one.
Tech support is practically non existent ( email only and they don't answer their phone and they don't listen to your messages if you leave one) and but the solutions they did offer didn't work then they told me I had the wrong jb4 connect despite me ordering the one labeled specifically for my car. They have a lot nerve charging this much money for a non functioning app that for some reason I can't get refunded.
