SELECTING THE MAP POSITION
The Dynojet Power Commander Fuel Controller (PCFC) comes loaded with up to ten
maps. Using a #1 Phillips screwdriver, turn the map select dial to toggle between the
loaded maps. Refer to the map position table for the maps included in your PCFC.
USING THE RPM RANGE DIALS
The Low, Mid, and High RPM Dials refer to the RPM range, in thirds, of your vehicle.
Each dial allows +/- 10% fuel adjustment on top of what fuel changes are done in the
map. With the dial facing straight up, there is no additional fuel change.
For example, if your vehicle revs to 6000 RPM:
• The low RPM dial will adjust 0-3500 RPM
• The mid RPM dial will adjust 3501-7000 RPM
• The high RPM dial will adjust 7001-10500 RPM

ALTERING MAPS USING SOFTWARE
The values in the map represent a percentage of fuel change over stock. A value of 10 in
the map indicates at that throttle position and RPM range the vehicle will be 10% richer
than stock. If the value is -10, then it would be 10% leaner than stock. You have the
ability to fine tune your fuel curve by altering these values. The Control Center software
allows a value of +250 to -100 in each cell.

The PCFC for this model controls the stock closed loop area. This area is
represented by the highlighted cells shown in Figure G. The PCFC is designed to
achieve a target AFR of 13.6:1. To use this PCFC you must retain your stock O2
sensor.
It is not recommended to alter the values in the highlighted area unless instructed to
do so by a PCFC technician.
The closed loop range can be adjusted from the PCFC software by going to
Device Tools >Closed Loop Adjustment. In this window you can use the slider
bars to enrichen/lean the closed loop range. We do not recommend an adjustment
