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, LLC, 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,

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.
This guide covers the installation of three difference products. The N55 Stage1, the JB4_F30 for pneumatic wastegates
(generally 2013 and earlier models), and the JB4_EWG for electronic wastegates (generally 2014 and newer models).
The control box determines whether the tune is a STAGE1 or a JB4. Failing to install JB4 specific connections will not
allow a JB4 to simulate a STAGE1.
1) Remove the plastic engine cover. The cover simply lifts off. Also remove the passenger side cowl cover which is
secured by 3 10mm plastic release bolts. Turning the bolts 90 degrees each will release the tab and allow you to pull
the cover off.
2) The harness is divided in to wire loops each with its own wire color which will be routed to a specific sensor on the
vehicle. In addition the JB4 models include green and brown CAN wires that will connect to the CANbus using the
included removable posi-tap connectors. JB4_F30 for pneumatic wastegates includes also includes a power and
ground wire.
3) TMAP sensor: All models
The TMAP sensor is located on the driver side of the engine bay, on the charge pipe leading in to the throttle body.
Disconnect the TMAP sensor plug and plug it in to the JB female rainbow connection. Plug the male rainbow
connection in to the TMAP sensor completing the loop. If you have difficulty removing this sensor plug the JB harness
male and female in to each other and practice on how to remove them. Using a small screwdriver from the back side of
the clip sometimes makes removal much easier.
4) MAP Sensor: All models
The MAP sensor is located on the top of the engine towards the back. It is visually identical to the TMAP sensor.
Disconnect the MAP sensor plug and plug it in to the JB female brown connection. Plug the male brown connection in
to the MAP sensor completing the loop.
5) Blue Patch: JB4_F30 only. Not used by STAGE1 or JB4_EWG.
Like the first two connections you unplug the OEM connector and connect it to the JB4 blue harness male, and then
plug the JB4 blue female on to the solenoid. If your vehicle does not have a solenoid here you are an "electronic
wastegate" (EWG) vehicle. If you are STAGE1 or EWG and have this blue connection on your harness just tuck it out
of the way.
6) GREEN/BROWN CAN Wires: All JB4 models. Not installed with STAGE1.
The green and brown CAN wires protruding from the TMAP connection will extend over to the CAN access point on
the driver side shock tower.
Review the directions for using the removable quick connections below. If needed practice on an extra wire so you get
a feeling for how they install and remove. It's pretty simple once you've done it.
Using the included removable quick connects attach the brown wire to the right most CAN wire as shown. The one
right below the thick red power wire. Using the included removable quick connects attach the green wire to next spot
immediately to the left of the first wire. Note those with automatic vehicles who wish to use a more discrete
installation location for the posi-taps can install them under the factory conduit as shown in the manuals transmission
directions.
Manual transmission cars: your CAN wires are in a different spot. Refer to the MT CAN wire section at the bottom of
this guide.
7) Black ground wire: Install on JB4 models equipped with the wire in the harness. Note newer JB4_EWG harnesses
include a special EWG specific JB4 board and have this wire deleted. This wire is not to be installed for STAGE1
systems.
Connect the black ground wire to the shock tower or any other suitable chassis ground.
8) Red power wire: Any JB4 model equipped with the wire in the harness. Note newer JB4_EWG harnesses include a
special EWG specific JB4 board and have this wire deleted. This wire is not to be installed for STAGE1 systems.
Connect the red power wire to the jumper battery position next to the control box. Note a T50 torx bit is required to
unscrew the connection.
9) Placement of the JB control box is critical as it must be kept in a generally dry location. We suggest positioning it
so that it is parallel with the strut brace as shown below. When the plastic cover is reinstalled this position will prevent
water damage to the control box. The optional USB cable should generally only be installed when doing diagnostics.
When not doing diagnostics remove it from the control box. Alternatively it can be left installed full time and routed
through the firewall in to the glove box by removing a rubber plug and cutting a small hole in the interior carpet as
shown below.
For those in extremely wet areas or those who wish to run without the engine covers you can also cover the JB control
box with a plastic membrane such as a zip lock bag or other suitable water tight cover. Heat dissipation is not an issue
with the control box.
When reinstalling the cowl cover be sure it's fully seated and that you've lifted the rubber seal around it. Failure to
properly secure this cover may result in water damage to your JB4.
Other wires on your harness that haven't been covered yet:
Purple patch: Not used on any F series model. This is a hold over from the E series models and was deleted from the
harness on newer models. Tuck it out of the way.
Black patch: We've added the FLEX_FUEL connector to newer JB4 harnesses which can be connected if you plan to
utilize E85 fuel mixtures. Refer to the FLEX_FUEL guide for additional information. It can be tucked out of the way
until you wish to connect it.
15) Reconnect negative battery terminal.
Installation is complete! Refer to N54tech for any additional install notes and info.
With the STAGE1 there is no map changing or tuning adjustment.
With the JB4 refer to additional directions on n54tech. Note the JB4 has cold oil temperature protection built in and it
will remain off until oil temps are greater than 160 degrees and the oil is thin enough to properly lubricate the turbo at
higher boost levels. Also note the JB4 is an adaptive tune so it will learn and adjust as you race the vehicle.
Quick connect directions:
Manual Trans CAN wires:
The manual transmission F30 has its CAN wires located in a bundle leading to the ECU. Remove the small piece of
tape holding the bundle together and fish out the red blue/red wire pair and connect as shown.
TMAP ground bypass required if USB cable touches battery rail, install wires with battery connected, etc. If
you get a check engine light with the tuner completely removed you likely damaged the TMAP ground and need
to perform this step to repair it.
