B. Main Menu
The Main Menu is shown below:
MAIN
Æ
Fuel Stats
MENU N2O Map1U
The current selection is shown by the Right-Arrow and the cursor (underscore below the “F”). Use the arrow keys to
move the cursor. Move the cursor to the desired selection and press the “SEL” key to select the desired menu option from
one of the following:
Fuel Go to the Fuel adjust menus (see Section 1). Here you can tune according to RPM and turbo boost.
Stats Display runtime data, captured data, and recorded maximum data (see Section 3).
N2O Go to the configuration menus for optional Boondocker Nitrous kit (see Chapters VII and IX..).
Map Go to the Map management menu (see Section 2). Additional nitrous configuration and tuning factors
are also found by selecting MapXX and StUp.
The current Map number is displayed as “Map1U”. This indicates that map number 1 is being used and it is Unlocked.
1. Fuel Adjust Menus
From the Main Menu, select FUEL to make adjustments for RPMs, turbo boost, and accelerator pump.
1.a RPM-based Tuning – There are four RPM-based Fuel adjust screens (examples shown below). The first screen
comes up after selecting Fuel from the Main Menu.
Fuel screen1: M1U Id LO MD
3000 00 00 00
Fuel screen2: M1U LO MD HI
5000 00 00 00
Fuel screen3: M1U LO MD HI
7000 00 00 00
Fuel screen4:
M1U LO MD HI
8500 00 00 00
Use the Left/Right Arrow keys to switch between the LO/MD/HI load ranges. Use the Up/Down Arrow keys to change
the fuel settings. Go to the next adjustment screen by pressing the “SEL” button. After pressing the “SEL” on the last
RPM-based Fuel adjust screen, you will go to the first turbo Fuel adjust screen.
The RPM-based fuel adjustments can be made according to the following two factors: RPM and Engine Load.
RPM Regions:
Four or more RPM regions are pre-programmed into the control box which allow fuel adjustments to be made at specific
RPMs. Whenever the engine RPMs are between these specific RPMs, the fuel adjustment will be the result of the adjacent
RPM fuel settings blended together proportionately. For example, the fuel setting at 5000 RPM is centered at 5000 RPM,
but this value also has an affect on fuel whenever RPMs are above 3000 RPM and below 7000 RPM (the two adjacent
settings for this example). Suppose the 3000 fuel setting is at “4” and the 5000 fuel setting is at “8”. If engine RPMs are at
4000 (mid way between 3000 and 5000) the actual fuel adjustment made will be “6”, which is mid way between “4”and
“8”.
Load Ranges:
Each RPM Region is split into 3 load ranges: LO (low), MD (medium), HI (high). Each load range is roughly equivalent
to the throttle position divided into thirds: LO is closed throttle (idle) to 1/3 open, MD is 1/3 to 2/3 open, and HI is 2/3 to
full open. During light-throttle conditions (slow cruising or deceleration), the LO RPM settings will be used. During part-
throttle conditions (normal or faster cruising), the MD RPM settings will be mostly used. During heavy-throttle conditions
(accelerating or heavy load operation), the HI RPM settings will be used.
