tr This adjustment is to Trim the PTO cylinder (injector connector with green/brown wires). This is used to add
or subtract fuel on the PTO side if fine-tuning is desired. The LO adjustment is not affected by the Trim value –
trim is only used for the MD and HI settings. It is best to tune the right (mag) cylinder first then make
adjustments to the left (PTO) cylinder if necessary. If more than a small amount of adjustment is required
(greater than plus or minus 7), check for other problems first (such as incorrect harness connections to the PTO
cylinder).
00
Fuel adjustment value. Each setting can go from –99 to 127. Refer to the EFI tuning section for general tuning
guidelines. A value of 00 means no fuel adjustment will be made and the original injector signal will be passed
through unmodified. Negative values will reduce the fuel. Positive values will increase the fuel.
Note 1: Each number is equal to about 1/2% of the total available fuel. The maximum available fuel will vary
with each engine as well as with elevation and air temperature.
Note 2: It is possible to max the injector (duty cycle > 100%) before the adjustment setting is maxed! Pay
careful attention to EGT’s, O2 readings, and fuel pressure when running with engine mods that require a lot of
additional fuel!

This is the last screen displayed when in the Fuel menus. This screen is used to control fuel when the control box senses
acceleration (like an accelerator pump). Below is a description for each field show in the above screen:
M1U This displays current map that is being used – in this case, M1 stands for Map1
AM This displays the Amount of fuel to be added (if number is positive) or subtracted (if number is negative)
during Acceleration. This fuel amount will be summed with any other current fuel modifications being made
by the Control Box. This means during acceleration the final fuel adjustment amount will be the amount due
to the Control Box RPM and/or Nitrous settings in addition to the AM fuel setting.
DR This displays the Duration in engine cycles that the fuel shown in AM will modify the existing fuel during
Acceleration. The accelerator pump feature will be turned off if this value is zero and no fuel adjustments will
be made. The Acceleration fuel adjustment will be turned off whenever deceleration is detected (throttle is
backed off) regardless of the DR value.
Sens This displays the Sensitivity that is used to detect engine acceleration. Higher numbers make this Less
sensitive. Do not use zero, or acceleration will be on all the time! Suggested values are between 6 and 20,
start with a value between 8 and 10.
Note: The Stats Screen will display an “A” and a
solid block on the right-side of the screen to indicate
when the Accelerator pump feature is active as
shown: Stats Screen indicating Acceleration:

4. Map Menus
From the Main Menu, select Map1U to go to the Map Menu (shown below). This screen is used to
Load/Copy/Lock/Unlock saved “maps” that contain fuel and N2O settings. Five maps (Map1-Map5) are available.

When a new map is loaded, the current adjustment settings will be changed to the values from that map. To load a
new Map, first move the cursor to select Load and press “SEL”. The following Load/Lock Menu will be
