I. Theory of Operation:
The Boondocker Control Box connects between the sled’s ECU (Electronic Control Unit) and the fuel injectors. It does
not reprogram or communicate with the ECU. It only modifies the existing signals sent from the ECU to the fuel injectors.
By modifying only these signals, it is possible to make fuel changes while keeping the stock fuel map. This means the
ECU can still compensate for engine speed, throttle position, barometric pressure, engine temperature, air temperature, etc.
The Control Box can reduce fuel or increase fuel amounts for certain rpm ranges and load conditions. This is done by
changing its fuel adjustment settings by using the buttons and LCD display. As with tuning a carburetor, it is possible to
go too rich or too lean!
Note: Be sure you know how to properly tune an engine before you adjust the fuel settings! Use of an Air/Fuel Gauge and
plug readings are highly recommended when tuning.
IMPORTANT NOTES – READ THIS!
Note1: Never unplug the Control Box when the engine is still running! Electrical damage may result which is not
covered under warranty!
Note 2: We recommend using Dielectric Grease on all connections to help prevent corrosion on the terminals.
Note 3: Avoid exposing the Control Box to environments where static charges may exist. For example, quickly
removing a sled cover from the sled in a dry environment can create a static spark that will damage the box (especially if
the box is mounted up on the handlebars).
Note 4: The Control Box is sealed – do not take it apart or it will no longer be sealed. The Control Box is designed to be
splash-proof. Do not submerge or subject the box to high-pressure spray. During long periods of non-use it is
recommended that you do not leave the control box exposed to the elements.
Note 5: Always use Resistor Spark Plugs! Non-resistor plugs WILL cause electrical interference with the Control Box.

There are two 10-pin connectors at the end of the black cable on the control box. One is for the EFI Harness and the other
is for the optional Nitrous Harness. These two connectors are keyed (male/female) so only the correct harness will fit into
the correct plug-in.
Note: Use Dielectric Grease on all plug
connections to help prevent corrosion on the
terminals.
The EFI harness plugs into the stock sled’s injector
connectors as follows:
1. Disconnect the stock harness connector from
each fuel injector. Note which connector goes
to which injector.
2. Determine where the control box will be
mounted and how the harness will be routed.
Route the harness so the injector connectors end
up near the sled’s fuel injectors.
3. There is a left (PTO) and right (MAG) pair of
connectors for each injector (see picture). The
connector pair with the Yellow and Tan wires
goes to the MAG side, and the connector pair with the Green and Brown wires goes to the PTO side.
4. Plug the gray Control Box connector (female) to the sled’s fuel injector, and the black connector to the sled’s gray
injector connector. Do this for both the MAG and PTO sides. The space above each injector is tight – it may help to
rotate the injector 90deg to install the connector, and then rotate it back.
Note: Be sure the black harness connectors latch securely to the gray injector connectors. This may require pushing
the latch on the gray connector down over the tab on the black connector. Do not force the connectors – check for
bent pins.
5. Connect the Control Box harness ground eyelet to a bolt on the chassis. A good ground connection is extremely
important!
6. Use zip ties to keep the harness away from moving parts. Use reflective heat tape if the harness must be routed near
hot items such as the exhaust.
III. Control Box Mounting Locations
The Control Box can be mounted under the hood, on the dash, or on the handlebars using the supplied Velcro strips.
Before applying the adhesive strips, thoroughly clean each surface (rubbing alcohol works well). It is also best if each
surface is room temperature.
If the box is mounted under the hood, keep the box away from excess heat (like the exhaust), and away from the ignition
coil.
Note: The Control Box is designed to be splash proof. Do not submerge or subject the box to high-pressure spray.

The supplied Battery/Jumper Connector has a dual purpose. It can function as a battery connector in order to supply
voltage to the Control Box when the engine is not running, and it can function as a jumper in order to bypass the Control
Box.
1. Battery Connector
The Control Box is designed to operate without a battery –
the box will turn itself on whenever power is applied for the
fuel injectors. However, a 9-volt battery (not included) can
be plugged into the box through the Control Box’s
connectors with the supplied battery / jumper connector
in order to operate the box without the sled running. This
battery connector plugs into the Control Box’s nitrous
connector (refer to picture below). Secure the battery to the
connector with a zip tie in order to provide a strain relief for
the 9-volt connector. The battery can also be secured to part
of the harness if it is to be used on the sled while it is
running.
The battery connector can be left plugged in during engine
operation, but the nitrous harness (if used) cannot be
plugged into the Control Box. The battery will eventually
drain if left connected to the box, so it is best to disconnect
the battery when not in use.
2. Jumper Connector
The Battery/Jumper connector can also be used to bypass the Control Box in case the sled needs to be run without the
Control Box. Disconnect the Control Box from the EFI harness and plug in the Jumper connector - the injectors are now
connected directly to the sled’s ECU.
V. Control Box Operation
The control box is powered only when the injectors are on which occurs for a few seconds when the key is first turned on
or when the engine is running. Up to 5 different fuel adjustment maps are stored in the box (currently all with zero values).
The box will remember what map was last selected and what its settings are – you do not need to do anything to save a
map when making adjustment (see Fuel Adjustments below).
A. Intro / Startup Screen
When the box is first turned on (by the engine or battery), the Intro screen is displayed. Press any key to go to the
main menu. An example Intro screen display is shown below:
Yamaha Phazer v:4B5bBD N2O:Adj
In the example shown above, this screen displays the following information:
Yamaha Phazer Sled model. This box is designed for the Yamaha Phazer. Boxes for other sleds will
have other lettering.
v:4B5bBD This is the software version of the box. The box can be reprogrammed only by sending
the box back to Boondocker

B. Main Menu
The Main Menu is shown below:
Main Fuel Stats
Menu N2O Map1U
The current selection is shown by the Right-Arrow and the cursor (underscore below the “F”). Use the arrow keys to
move the cursor. Move the cursor to the desired selection and press the “SEL” key to select the desired menu option from
one of the following:
Fuel Go to the Fuel adjust menus (see Section 1).
Stats Display runtime data, captured data, and recorded maximum data (see Section 3).
N2O Menus for optional Boondocker Nitrous kit (see Chapters VII and IX..).
Map Go to the Map menu (see Section 2)
The current Map number is displayed as “Map1U”. This indicates that map number 1 is being used and it is Unlocked.
1. Fuel Adjust Menus
This selection is used to make fuel adjustments. There are four Fuel adjust screens (examples shown below). The first
screen comes up after selecting Fuel.
Go to the next screen by pressing the “SEL” button. After pressing the “SEL” on the last Fuel adjust screen, you will
return to the Main Menu. Use the Left/RightArrow keys to switch between settings. Use the Up/DownArrow keys to
change the settings. Sample Fuel adjust screens are shown below (actual rpm settings and number of screens may be
different for your model).
Fuel screen1:M1L LO MD N2 DL

The fuel adjustment rpm ranges are blended as shown in the picture above. This allows for a broader range of adjustments
with fewer steps. Each fuel setting is centered at a particular rpm value, in this example: 3000, 5000, 6700, 7800, 8100rpm.
Each region is blended with the region below and the region above it as shown. For example, if the rpm is at 4000, the
adjustment value will be half the value of the 3000 setting plus half the value of the 5000 setting.

M1LThis displays current map that is being used – in this case, M1 stands for Map1. Five possible fuel maps can
be used. Each map consists of all your configuration and fuel settings for a particular setup. The “L”
indicates that this map is Locked – this means the settings cannot be changed (the up/down buttons have no
effect). If the map is Unlocked, adjustments can be made to any setting and these changes will be
automatically saved to the selected map. Refer to the Load/Copy sections for more details about how to lock
and unlock individual maps.
3000 This is the RPM Regionfor the fuel adjustments on this screen. For this example, this screen’s adjustments
will be centered at 3000rpm. There are usually 5rpm regions (some boxes with special programming will have
additional regions). The effect of the 3000rpm setting tapers off until 5000rpm (as shown in the picture
above), while the effect of the 5000rpm setting is ramping up. The other regions work similar to this.
LO This adjustment is for Low load conditions. This will affect throttle settings from approximately 0 up to 1/3.
For rpm region 3000, this adjustment will affect idle. For other rpm regions, this will affect deceleration and
light-load cruising conditions.
MD This adjustment is for Medium (mid-range) load conditions. This will affect throttle settings from
approximately 1/3 up to 2/3.
HI This adjustment is for High load conditions. This will affect throttle settings from approximately 2/3 to full
open.
tr This adjustment is to Trim the PTO cylinder (left-side cylinder when sitting on the sled). This is used to add
or subtract fuel on the left side if fine-tuning is desired. The LO adjustment is not affected by the Trim value – trim is only used for the MD and HI settings. It is best to tune the right (mag) cylinder first then make
adjustments to the left (PTO) cylinder if necessary. If more than a small amount of adjustment is required
(greater than plus or minus 7), check for other problems first (such as incorrect harness connections to the PTO
cylinder).
