D. N2O Pressure Transducer Faults
If the Nitrous Mode is set to FIX, the pressure transducer is ignored and no Nitrous faults should appear. If the
Nitrous Mode is set to ADJ or NON, when the nitrous button is pressed, the Control Box first checks to make sure
the readings from the pressure transducer are correct. One of the following two fault messages may be displayed. If
a fault message is displayed, the nitrous solenoid will not operate and the message will remain displayed until any key
is pressed to clear it or the engine is restarted.
ERROR: N2O press
too LOW! .
This screen may appear if the pressure in the N2O tank is zero, the transducer is unplugged, or there is a wiring
problem.
Important Note: If the bottle becomes empty, this message will be displayed and nitrous will be shut off to prevent
extra fuel from being added without nitrous!
ERROR: N2O press
over 2000psi .
This screen will appear if the pressure transducer senses a pressure above 1000psi for regulated systems or 2000psi for
non-regulated systems.
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.
Other Issues
Engine runs erratically:
1. Verify that the ground on the sled’s harness has a good connection to the chassis.
2. Verify that the EFI Harness Ground Wire has a good connection.
Note: The ground wire on the Control Box must be connected to CHASSIS GROUND (not Engine ground!).
3. Verify that all wiring is in good condition and that the wires have not pulled out of the terminals. To verify this,
look inside each connector and verify that the terminal pins are all at the same height. If a terminal is starting to
