Selecting the Map Position
The Juice Box Pro 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 below for the maps included in your Juice Box Pro.
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 15,000 RPM:
• the low RPM dial will adjust 0-5000 RPM
• the mid RPM dial will adjust 5001-10000 RPM
• the high RPM dial will adjust 10001-15000 RPM

Altering Maps Using Top Tune
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 Top Tune
software allows a value of +250 to -100 in each cell.
