sparkplug electrodes, speckling on the sparkplug insulator, or shiny or gray flakes on the
electrode which could be melted aluminum from the piston. If possible, watch the crown of the
piston (near exhaust port) for a pitted or sand-blasted look. EGT’s can sometimes read low
during detonation – heat is going into the cylinder and piston instead of out the pipe.
Timing
Timing can affect the pipe temperature. Generally if the ignition is retarded, more heat will build up in
the pipe. Too much advance may drop EGT temps, but increase cylinder temps. Stock timing seems to
work best for this turbo.
Fuel
Different fuels have different specific gravities (densities) and other characteristics which can affect
your mixture requirements from one fuel to another – be aware of this if you change fuels. Oxygenated
fuel will run leaner than non-oxygenated fuel and is not recommended.
Lean spots
Sometimes a motor runs hot at certain rpms and throttle positions (usually in its mid-range) no matter
what. The fuel adjustment settings can be used to richen this up, but the engine may quickly become
too rich and run erratic. Under light load conditions you can sometimes get away with running hot for
short periods of time. Under such conditions it is best to vary the throttle position often and not stay at
one throttle setting for long durations.
IX. Control Box Troubleshooting
Stuck Button
When the Control Box is first turned on, all buttons are checked to verify that a button is not stuck on. If a button is
detected to be on during power up, the button will be disabled and the following message will be displayed until
another button is pressed. To verify if a button really is stuck on, re-power the box without pressing any buttons.
Button is Stuck!
Note: A common problem is a bad ground connection on the sled causing the box to keep resetting itself. If a button
is being pressed when this occurs, the “button stuck” message will be displayed. Start the sled without pressing a
button and see if the message goes away. If it is not present, start looking for a disconnected ground on the sled (see
Other Issues below).
If a button really is stuck on, the Control Box can still function and adjust fuel properly. The Control Box can be sent
back to Boondocker to be serviced.
Injector Fault
The Control Box monitors the signals from the sled’s ECU. If it detects signals on one set of wires but not the other, it
will detect a fault on that injector and display one of the two error messages.
MAG Inj. Fault!
Missing or bad signal detected on the MAG side injector (yellow or tan wire).
PTO Inj. Fault!
Missing or bad signal detected on the PTO side injector (green or brown wire).
xxx Inj. Fault!
This means a previous injector fault has occurred which has not yet been
cleared.
If any of these conditions occur, the Control Box will still function and it will still try to make fuel adjustments, but
the intermittent injector connection will need to be fixed. Contact Boondocker to determine if the Control Box and
harness need to be sent back to be inspected or serviced.
Note 1: Injector errors that occur infrequently can be ignored since they are likely caused by sporadic electrical noise.
