Use subject to terms and conditions posted at http://www.burgertuning.com/terms.html

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

Hey guys,

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.

To order a new F series JB4 kit: http://burgertuning.com/N55_JB4_F_ch...BMW_tuner.html

To avoid cluttering up the thread any support requests will be deleted from this thread without being read. If you require assistance email tech support at jon@burgertuning.com.

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.

If you need directions on how to connect a laptop to your JB4 to update firmware, datalog, or change maps via the laptop interface Click here.

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 WMI mapping.
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.

E85 Use

Up to 30% E85 mixtures can be used in most situations.

Firmware

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.

535 Differences

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.


************************************************** ************************
*Special Settings For F Series JB4 EWG & PWG version 11+
************************************************** ************************


FUD:
bit0 - Disable in dash BC button controls
bit1 - Alternative in dash BC F10 compatibility mode
bit2 - Disable oil temp warmup protection -- full boost target when oil temps < 160
bit3 - Disable wastegate/FF adaption learning for diagnostic purposes
bit4 - Enable user adjustable progressive meth control
bit5 - Disable port injection mapping tip in gain
bit6 - Enable extra timing cylinder logging
bit7 - Slow down CANbus sample rate - required for some vehicles with older software

FutureUseA: Negative offset to dutycycle via EWG connector to correct for over boost conditions when PWM is low

Map6: Values of less than 10psi under boost 1500rpm will cause map6 to act as an additive rather than absolute map


Firmware notes:

N55_FSERIES_OBDII_EWG_12:

1) Adjustment for those running high boost back end flash maps.

N55_FSERIES_OBDII_EWG_11:

1) Revised FUD settings to bit logic allowing multiple selections. Settings are as above. Note revised FUD bit options are for v11 and higher firmware ONLY.
2) Changes to partial throttle mapping to improve smoothness.
3) By default cyl1 and cyl5 only are logged to speed up sample rate. Other cylinders are loggable via a FUD bit 6.
4) Various other minor changes.
5) Various changes to PI mapping and other test features under development.

N55_FSERIES_OBDII_PWG_11:

1) Minor changes to bring PWG firmware up to current EWG firmware specifications.


EWG Control

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:



In dash options

Note CANflap and menu system for changing maps, enabling the boost gauge, etc, now use exclusively the BC button.

'***************************************
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. (OFF tach = 0, ON tach = 1000)
'3 LED MAX brightness mode. For those with factory LED headlights this option brightens HALO during nighttime operation. (OFF tach = 0, ON tach = 1000)
'4 Delete Fault Codes.
'5 1st gear boost limit setting. 0-7000rpm = 0-20psi.
'6 2nd gear boost limiter
'7 3rd gear boost limiter
