4.4 Map – StUp (SetUp)

Select “StUp” to change the N2O regulator Mode. Use the Up/Down arrows to change between: “ADJ” if an
adjustable nitrous regulator is used, “FIX” if a fixed nitrous regulator is used, or “NON” if nitrous is non-regulated.
Press “Sel” to go back to the MAP Menu.

N2O Regltr Mode:

ADJ


5.2 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

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/DC.


5.3 Stats: N2O/TPS

This menu displays nitrous information.

N2O PSI MxTP Clr

.

32 240 208 Y

N

N2O 32

Maximum fuel adjustment during last nitrous activation (blacked out

during nitrous

activation). This can be cleared manually and is always clear upon next nitrous activation.

This can be cleared manually and is always cleared upon next nitrous activation.

PSI 240

For systems without a N2O pressure regulator (NON in lower right-hand corner of Startup
Screen
), this displays current nitrous tank pressure. For systems using a N2O pressure regulator
(ADJ or FIX in lower right-hand corner of Startup Screen), this shows the maximum nitrous
pressure during the shot, where the pressure is measured after the solenoid valve. The
maximum is averaged over a 1 second period.

MxTP 208

Maximum throttle position reading since this menu was last cleared or since engine was last
started.

Selecting Y will clear these 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
Exhaust Gas Temperature gauges can be an effective tuning tool, but they are not a substitute for reading spark plugs and
piston wash and feeling how the engine runs. Use EGTs only as a backup to verify what you see. They can be misleading
