I strongly suggest testing everything while you have access to the JB4, just to make sure everything works as expected.





Settings Descriptions:

WOT Start Threshold - The pedal percentage required to start an auto-WOT log.


WOT Logging Timeout - The number of seconds before stopping a log after the pedal goes below WOT Start Threshold.


Ignores Auto-Logging w/Clutch Active - Don't start an auto-WOT log if pedal goes above WOT Start Threshold while the clutch is depressed (ex. downshifting).


Log File Suffix - The name to append to the end of your logs.  I set this to the name of the current flash I'm using.


Shift Indicator RPM - The RPM to activate the shift animation.


Shift Indicator Color - The color of the RPM shift indicator animation.


Temperature in Celsius - Display IAT, Oil Temp, and Water Temp in Celsius.


Attempt Auto-Connect on Launch - Try to connect to the Connect Kit as soon as the app is opened.


GPS (and FUD 4) Speed in KPH - Display these speed outputs in KPH instead of MPH.


HUD Mode - Mirror the entire display.


Bar Boost Units - Display the boost gauge in Bar units.


Using Ethanol Kit - Enable this setting if using a Fuel-It Ethanol Integration Kit.


Disable WiFi Warning - Disable the WiFi popup warning.


Demo Mode - Animate the gauges without a connection.


Developer Mode - DO NOT TOUCH THIS UNLESS INSTRUCTED TO BY ME.





Basic Use:

To change what a gauge displays in the app, simply tap and hold on the gauge and a selector view will appear.


To view your max boost, double tap the boost gauge.  Double tap again to view current boost.  Note the max boost will be reset after you go back to the normal boost gauge.


To calibrate the G Force gauge, bring the car to a complete stop on a flat surface then double tap the G Force gauge.


To export a log simply tap the desired log and hit email.  To export multiple logs select "Select", tap the desired logs to export, then tap email.




Firmware Downloading (via Email Client):

Click the hex file.


Open in JB4 Mobile.


Open JB4 Mobile.

Select your newly imported hex file.





Firmware Downloading (via JB4 Mobile's built-in web browser):

Browse N54Tech and find the desired hex file.


Click it to start downloading.


Go to the firmware update page.

Troubleshooting:

*None of my gauges are working:


1) Make sure your JB4 isn't on map 0.


2) Kill and restart the app.


3) Take a log and see if you're getting any readings.


4) Ensure your CAN wires or OBD hookup is properly installed (it's usually this issue).



*My Oil Temp, Water, and Trans Temp gauges aren't working:


1) Does your engine type's JB4 support oil/water/trans temp?  If not, this feature doesn't work for you at this time (firmware limitation, nothing I can do about it).


2) If it does, is your firmware updated to the latest version that includes that functionality?



*I keep getting "Error connecting to JB4." and can't connect:


1) Disconnect then reconnect the DB9 connector ensuring it is screwed in.



*I keep getting "No BLE Devices Found." and can't connect:


1) Verify the red wire is properly connected to the power source.


2) Disconnect then reconnect the DB9 connector ensuring it is screwed in.
