"Installed this app when I got my Jb4 with bluetooth for a 2019 Honda Civic Type R. Couldn`t get it to work right so I emailed them. They got back to me right away to solve my issue. I was surprised at how communicative they were. Because of that, I highly recommend both the Jb4 and the app. Also, the app itself is pretty awesome."

"Works well, zero connection issues. I believe the placement of the Bluetooth adapter on the JB4 is the reason for some issues people are having. I placed mine where the install instructions recommend and have never had a single failure to connect. This thing makes a very noticable difference and increase the fun factor of driving my vehicle. I can`t imagine driving without it now. Zero fault codes because of the JB4. Worth the money and definitely go for the Bluetooth/app combo."

"awesome app but need to simplify each map so it says exactly what it is, i.e- instead of saying map 0 say ``STOCK MAP`` or for map 5 say ``POWER MAP 5`` or something along those lines..."

"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!"

"2016 F150 2.7 JB4 with bluetooth connection This app has allowed for seamless firmware/map updates. Have had zero connectivity issues switching maps. Can be done on the fly. Monitoring and logging works as advertised. Excellent addition to your JB4 firmware."

"MAP settings changed without notice. I have a JB4 w/Bluetooth for my 2017 BMW X6M. Without any warning or notification someone changed the MAP settings on this app so everything is f`d up now. This has the potential to destroy your vehicle. Don`t use this app!!!"

"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"
