Also consider the following:
A/F Mixture Generally EGT’s get hotter as the motor gets lean, but too lean and the temps can actually drop! As oxygen
is added, the flame gets hotter to a certain point, then too much air can can gradually cool things off.
Detonation Detonation often requires an experienced tuner to detect – in most instances it cannot be heard or
noticed. Careful examination of the piston and sparkplug are required. Watch for melted
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.
VIII. 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 on
during power up, the button will be disabled and the following message will be displayed until a button is pressed:
Button is Stuck!
If this condition occurs, the Control Box will 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 following error messages.
Injector 1 Fault
No signal detected on the MAG side lower injector (yellow wire).
Injector 2 Fault
No signal detected on the PTO side lower injector (green wire).
Injector 3 Fault
No signal detected on the MAG side upper injector (yellow/white wire).
Injector 4 Fault
No signal detected on the PTO side upper injector (green/white wire).
Injector x Fault
An error occurred that did not get cleared (by pressing any button) before the
engine was started again.
If any of these conditions occur, the Control Box will still try to function and adjust fuel properly. Contact Boondocker
to determine if the Control Box and harness need to be sent back to be serviced.
Other Issues
Engine runs erratic:
1. Verify that the EFI Harness Ground Wire has a good connection.
