THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of this part, and Burger Motorsports, Inc hereby disclaims any liability resulting from the failure to use this part in compliance with all applicable federal and state laws.
When working with live wires ALWAYS disconnect the negative battery terminal in the trunk first. Do not attempt to install the tuner, connect the tuner box to the harness, or otherwise work on the vehicles electrical system with the battery connected. Doing this may result in a damaging voltage spike being sent to the DME.
Also be very careful when working with the BMS USB cable as it sits close to the battery rail which is a live +12v connection. Allowing the USB cable to touch the +12v connection WILL damage the JB4 and MAY damage the TMAP sensor wiring requiring the ground bypass at the bottom of the guide to be performed. Wrapping a piece of cloth tape over the battery rail connection and/or USB connection will help prevent accidental damage.
Current F Series JB4 Install Guide
This thread will be used to centralize all F series JB4 information. Anything important is in the first post. The rest is 100 pages of discussion, much of which may no longer be relevant. If its not in the first post then its probably not very important.
Note: We sell two systems for the F series N55. The Stage1 and the JB4. There is no such thing as a JB4 Stage1 and no such thing as a JB4 Stage2. The Stage1 DOES NOT have updatable firmware, CANbus, or changeable maps. If you have a Stage1 system then none of the information in this post is relevant to you.

JB4 Interface: Latest JB4 Interface Download.
When updating your interface you may need to first go to "add remove programs" and "remove" your previous JB4 interface.

Map Info (selected via menu 0 in dash or using JB4 Mobile/laptop interface. Map1 is the default map)
Map 0: JB4 disabled
Map 1: Additive target, around 4psi over stock.
Map 2: Additive target, around 6psi over stock. Suggested for those with 93 octane and bolt on modifications. Also good for small E85 mixtures.
Map 3: Progressive methanol mapping, absolute target of 11-20psi based on meth flow, meth additive setting, and average ignition values.
Map 4: Stock performance with JB4 active for logging only.
Map 5: Autotuning map, absolute target of 11-17psi based on octane and conditions.
Map 6: User definable absolute target map. Suggested for troubleshooting by professionals only.
Map 7: Race gas map. Absolute target of 18.5psi. Requires straight unleaded race gas.
Models equipped with the pneumatic wastegate & flex fuel connector may experiment with up to 40% E85 mixtures. Some cars tolerate E85 and some do not. Cars that do not tolerate the mix will "buck" or "miss" at full throttle. In some cases map 7 can be used on the E85 mix and in other cases map 2 is the highest that can be used. It's best to start slowly and work your way up in terms of aggressiveness when experimenting with E85 mixtures.
Both the F10 and F30 N55 motors share the same firmware. Note models using the pneumatic wastegate, primarily 2013-early 2014 models where the JB4 harness blue patch is connected, need to use PWG firmware. Those equipped with an electronic wastegate, primarily 2014+ models where the JB4 blue batch is NOT used, need to use EWG firmware. Note for older systems POSITAP firmware (the old wire taps for brown/green wires) has been discontinued and no new updates will be done. So upgrade to the OBDII CANbus connector & firmware if you wish to run the latest firmware & features.
1) To enable the BC button menu changes on F10/535 models you must connect to the JB4 using a BMS DATA cable and change the "Future Use D" setting to 2 and press save. Then turn off ignition and lock doors for 5 min to allow the DME to reset.
N55_FSERIES_OBDII_PWG_9 & N55_FSERIES_OBDII_EWG_9:
1) Corrected bug with boost gauge and in dash settings not saving in certain situations.
N55_FSERIES_OBDII_PWG_8b & N55_FSERIES_OBDII_EWG_8:
1) Added FutureUseA = 51 option to slow down CANbus speed for those few vehicles that require it to get consistent logging. Typically older M135 models.
2) Added water temperature logging parameter.
1) Minor bug corrections and fixes
1) Increased sampling rate for 6cyl timing data
2) Minor map5 revision
3) Added support for Fuel-IT N55 Port Injection integration
1) Increased sampling rate for 6cyl timing data
2) Minor map5 revision
1) Added FSERIES To the name to avoid confusion among E series N55 owners.
2) Added automatic trans temp logging
3) Added output for oil temp for JB4 Mobile and updated JB4 interface
4) Added in timing on cyl 2-6 on a cycling scan of around 1hz. Will work on speeding up the timing data in future versions.
For those with 2014+ models with the new electronic wastegate this thread has addl information on optional EWG control for higher boost maps.
OBDII Firmware Wheel Controls and Map Switching In Dash:
Current in dash settings as of v1 firmware:
Note CANflap and menu system for changing maps, enabling the boost gauge, etc, now use exclusively the BC button. The old volume routine is no longer used once you install the OBDII CANbus.
Exhaust Valve Mode:
Toggle between flap open, flap closed, and OEM operation, by pressing the button for 2 seconds and letting go. The left blinker will flash for valve open, right blinker for valve closed, and both blinkers for OEM operation. The valve setting is persistent and will remain in effect until you change it. If you hold the button too long you'll jump in to the in dash menu system below.
'OBDII In Dash Menu
'0 map menu, map shown on tach. Note map guide above.
'1 Not used for this model
'2 Boost gauge on fuel, boost is shown in the fuel gauge under heavy throttle with empty being 0psi boost and full being whatever you've assigned to your boost failsafe PSI on the user adjustment page. Default is 18psi. To enable this feature move the tach from 0 to 1.
'3 LED MAX brightness mode. For those with factory LED headlights this option brightens HALO during nighttime operation. To enable this feature move the tach from 0 to 1.
'4 OBDII Diagnostic Code Delete
'5 1st gear boost limit setting. 0-7000rpm = 0-20psi.
'6 2nd gear boost limiter
'7 3rd gear boost limiter
