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

desktop or on your start menu.
3 Click Open Map File and select a map file.
4 Click Send Map. You can send the map to any of the ten map positions.
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.

Tuning Notes
This bike uses a fly-by wire system therefore conventional tuning can not be performed
for all RPM and throttle ranges.
The grey wire from the Juice Box Pro is attached to the throttle blade angle sensor of the
throttle bodies which is not directly correlated to the throttle grip position. When setting
the throttle position in the Top Tune software, we recommend on resetting only the
closed position after the bike has completely warmed up. Use the arrow key (<) next to
CLOSED to perform this step and then click OK. Do not try to set the OPEN position
unless you are on a dyno and above 9000 RPM.
You will notice in the maps there are not detailed values below 7000 RPM at 100%
throttle and below 5250 RPM at 60-80%. This is because the throttle blades will not open
more than 60% below this RPM range no matter how much throttle input is given.
Therefore this area can not be tuned.
