I. Theory of Operation:
The Boondocker 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 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 add or subtract fuel amounts for certain rpm ranges and load conditions. This is done by using the
buttons and LCD display to change its fuel adjustment settings. 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 Mixture
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 Silicone Dielectric Grease on all connections to help prevent corrosion on the terminals.
This is available from automotive supply stores, commonly labeled as “Light Bulb Grease”.
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 can 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.
