App Description
JB4 Mobile is a mobile data logger and display for use with the JB4 piggyback tuner from Burger
Motorsports.
To connect, simply attach the JB4 data cable to your device using an OTG cable.
***Use a good
quality OTG cable to avoid connection issues.
***If you keep getting "Serial port not available" errors, 1 of these
issues is probably the cause:
1) Your OTG cable is faulty
2) Your device either doesn't support OTG properly or
requires a powered USB hub
3) You're using a Galaxy S6/S6 Edge (see below)
Galaxy S6/S6 Edge Owners using an
OTG cable: It has come to my attention that to get these devices to work correctly, you must first connect the OTG
cable to your device, THEN connect the JB4 cable, THEN open the app and connect. Not sure why these devices are so
picky, but at least someone found a workaround.
JB4 Mobile allows you to monitor multiple parameters of your JB4
equipped car at once. Parameters such as boost psi, rpm, fuel trims, air/fuel ratios, ignition advance, fuel pressure
and much more are all available.

How to calibrate the G
Force meter:
1) Make sure your device is mounted in your vehicle in a (mostly) upright position (portrait only
support for now).
2) Select a G Force gauge on the display screen.
3) When the vehicle is at a complete stop on a
flat surface, simply double tap on the G Force gauge.
4) When the dot is centered in the circle with the car at a
flat rest you know it is calibrated.
To switch what a gauge displays, just tap and hold on that gauge and a
menu will appear.
To view your max boost, simply double tap on the boost gauge (double tap again to view live
boost, max boost is reset after viewing).

Good. The JB4 app cannot open or closethe CAN flap (at least for my car). Even if I managed to open the flap through the wheel JB4 cannot close and hold the flap. It opens back.
