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.
VI. Nitrous Tuning (for optional Boondocker Nitrous kit)
Important Tuning Note: Be sure to make non-nitrous (RPM-based) tuning adjustments first. Once the nitrous tuning
procedure has been done, any changes to the RPM fuel settings may affect nitrous fuel delivery. If this occurs, the nitrous
tuning steps will need to be done again.
On the startup screen (displayed when first powered on), note the message in the lower right-hand corner.
ADJ
– Configured for a nitrous system using an Adjustable or Fixed N2O pressure regulator.
FIX
– Configured for a nitrous system using a Fixed N2O pressure regulator.
NON
– Configured for a nitrous system that is Non-regulated.
Be sure that this description matches your actual nitrous system. Some internal settings and some user menus and settings
are affected by this configuration. Do not attempt to run a Non-regulated nitrous setup with the Control Box in ADJ
mode or a Regulated nitrous setup in NON mode! Go to the SetUp menu (under the MAP Menu) to change this
setting. If you do not have nitrous capability, then this configuration does not matter.
The fuel adjustment setting in the N2O menu is used to control how much fuel is added during nitrous use. The nitrous
pressure transducer input is used to automatically scale the fuel adjustment up or down from this base setting according to
nitrous pressure. However, you still must go through the nitrous tuning procedure before you can safely use nitrous.
Warning: Only adjust the control Box settings according to the steps below. The best way to tune an engine is
with the use of an oxygen sensor and gauge (available from Boondocker). This adjustment process should only
be performed by an experienced tuner. If you are not an experienced tuner, find someone who is. Remember,
safety first!
The steps below should be performed with a full nitrous bottle. On systems without a nitrous pressure regulator, make sure
the bottle is at proper operating temperature (70-90deg F) and pressure (700-1000psi). Make sure the engine is at normal
operating temperature.
*** Do not exceed 2 seconds of nitrous use until the fuel adjustment is complete and correct! ***
1. First configure the nitrous system for Button use. The next chapter will describe different ways to configure your
system for nitrous activation, but we’re going to shortcut that for now.
Select N2O from the Main Menu, move the cursor so it is under Btn and press the Up Arrow until N2O. Press
“SEL” to return you to the Main Menu. Select N2O from the Main Menu again. Look at the N2O Menu to be
sure that TPS and RPM are turned OFF.

2. Follow this step only if you have an adjustable N2O pressure regulator: Select N2O from the Main Menu. With
the cursor under Fuel, when you press the up, down, or “SEL” key, the following menu appears:
340 180psi FDly
050 025 000
The 340 and 180 fuel settings are
used to create a Fuel Adjustment
Line (see graph) which allows
nitrous fuel to be automatically
adjusted according to N2O
pressure. Raising or lowering
either of these values will change
the slope of the line.
