Run/Capture mode:

Left-Arrow button : Sets Capture Mode, “Cap” will be displayed and the current data will be frozen on the

display. The capture occurs on the display when the button is released (data will continue to
be captured if the button is held down). It will stay in capture mode (data will remain frozen)
until the Right-Arrow is pressed to return to Run mode or until the Control Box is re-
powered. If the Stats menu is re-entered before the engine is shut off and the box is in
Capture mode, the last captured data will be displayed.


Right-Arrow button: Clears capture mode (captured data will be lost!) and sets Run mode. “Run” will be

displayed and real-time data will be displayed. Note: The Button Mode can also be
configured to Capture the Status screen Press SEL to go to the next screen: Stats: MAX.

3.2 Stats: MAX

Any button press from the Run screen will go to the next Stats screen which is the Max screen, displaying max
RPM, Duty Cycle In from the sled’s ECU, and Duty Cycle Out to the injectors.


MAX:DCIn/Out Clr

.

5500 35/45 Y

Æ

N

.

MAX: 5500

Max rpm

DCIn 35

Max Duty Cycle Input from sled’s ECU.

DCOut 45

Max Duty Cycle Output to the injectors.

These max values will be saved when the box is shut off so they will remain the next time this screen is displayed
even if the box is re-powered. Peak values or “spikes” are filtered by finding the average during a certain time-
window. Therefore, a maximum must be held for at least 1 second to be recorded and displayed properly.

Use the arrow keys to move the cursor between Y and N. Pressing SEL when the cursor is on Y will clear the max
values. Pressing SEL when the cursor is on N takes you to the next screen: Stats: N2O/TPS.


3.3 Stats: PSI

This menu displays nitrous and TPS information.

12.2 13.4 Y

Æ

.

MAX 12.2

This is the average maximum boost amount measured in psi. The boost is averaged during a 1
second window in order to filter out boost spikes. This value should be very close to the actual
sustained boost. If the display shows “XX.X”, the boost value has exceeded the valid range.

Peak 13.4

This is the peak boost value. This is usually higher than the Max boost value by 1 to 2 psi due
to spikes on the boost pressure. If the display shows “XX.X”, the boost value has exceeded the
valid range.

Clr Y N

Selecting

Y will clear the save PSI Max/Peak values. Use any arrow key to select Y or N.

Pressing “SEL” takes you to the Main Menu.


VI. EFI Tuning Suggestions

Each Fuel adjustment setting goes from –99 to 127. Positive numbers add fuel and negative numbers subtract fuel. The
Control Box will not prevent a lean burndown! You must take the proper tuning steps the same as if you were tuning a
carburetor.

The maximum is set to 127. This does not mean you have an effective range all the way to 127 – you will likely max out
the injector before this setting is reached. Your usable adjustment range (max value) is dependent on how long the ECU
already has the injector on. This will vary depending on rpm, throttle setting, temps, and can be different from sled to sled
even of the same model. There is no direct relation
