NOTE : ONLY WORKS WITH EXISTING JB4 TUNERS

Wirelessly connect and control your JB4 with your phone or tablet! 

The JB4 Wireless Bluetooth Connect Kit (Rev 3.7) allows your Bluetooth 4.0 compatible Apple® iOS® and Android® devices to connect wirelessly to your JB4 via the JB4 app. View critical engine data in real time, datalog, read codes, change maps, update settings, update firmware, and more, all wirelessly from the palm of your hand!

The REV3 mounts next to the JB4 in the engine bay eliminating the need to run a BMS DATA cable inside the cabin. It's compatible with all JB4 products. Just plug it into the JB4 where your BMS DATA cable connects, purchase the JB4 Mobile app (see below), and you're off and running.

Please note the JB4 Mobile app is available for iPhone®, iOS®, or Android® and sold separately via the Apple® or Android® app store on your phone. The wireless adapter is not compatible with the JB4 windows interface. See our other listings for the "BMS DATA cable" for laptop use.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Easy Claims Process
It is not a long complicated process to file and resolve a claim. Be warned--sometimes they will want you to send back the defective or damaged product, even if it's not worth the shipping ---they pay. Overall worth the investment though.
