I. Theory of Operation:
The Boondocker Fuel Control Box connects between the sled’s ECU (Engine 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 adjustments while keeping the basic stock fuel map. This
means the ECU can still compensate for engine speed, throttle position, barometric pressure, engine temperature, ambient
air temperature, etc.
The Fuel Control Box modifies the stock fuel map to compensate for sled or engine modifications. It can reduce or
increase fuel amounts for certain RPM ranges and engine load conditions. This is done by changing its fuel adjustment
settings using the buttons and LCD display. As with tuning a carburetor, it is possible to go too rich or too lean!
The Control Box also activates nitrous delivery (nitrous kit sold separately) and adds fuel to achieve proper air/fuel
mixture. Again, as with tuning a carburetor, it is possible to go too rich or too lean! There are seven different ways to
activate nitrous using such factors as RPM, throttle, and a handlebar button or arming switch.
Other features include the ability to capture and display operational data, store maximum values, and save multiple setups.
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.
