 Note: (The ACEL feature is useful for precise tuning, and if misused can create a wide range of tuning 
issues. ACEL adjustment should only be made after all other tuning parameters have been properly 
adjusted. ACEL adjustments should only be made by persons with an in-depth knowledge of tuning and 
Boondocker control box use.) 
The ACEL feature is an electronic accelerator pump that can be used to add (or subtract) fuel according 
to throttle movement. When the throttle position is advanced (opened) the ACEL is activated. 
Sensitivity (SN): The set sensitivity determines how far or fast the throttle position should be advanced 
before the ACEL is activated. The value set below SN will determine the sensitivity, 01 being the most 
sensitive and 10 being the least sensitive, 00 being on all of the time. 
Amount (AL/AH): The set amount determines the amount of fuel that will be added (or subtracted) 
when the ACEL is activated. The value set below AL will determine the amount of fuel that will be added 
when the engine is being operated below 2.0 psi of boost. The value set below AH will determine the 
amount of fuel that will be added when the engine is being operated above 2.0 psi of boost. 
Duration (DR): The set duration determines the amount of time (number of engine cycles) the ACEL 
feature will add or subtract fuel each time the ACEL is activated. 
The extra (Xtra) screen contains features that can be used to add or subtract fuel when the adjustable 
specified parameters for PSI and RPM are met. Auxiliary button parameters can also be adjusted in the 
Xtra screen. 
Position the → (cursor) next to Xtra and press the SEL button to advance to the extra screen.
