APRILIA tuono v4 Owner's Manual page 30

The rider may cycle through the different engine maps by pressing the starter button,
which may be used to select maps once 5 seconds have elapsed after engine start.
CAUTION
THE RIDER MAY USE THE STARTER BUTTON TO SELECT MAPS EVEN WITH
THE VEHICLE IN MOTION, PROVIDED THAT THE ENGINE IS RUNNING AND THE
THROTTLE IS RELEASED.
To change engine maps, proceed as follows.
•
Press the starter button once. The symbol of engine map currently in use is
displayed in negative against a black background.
•
Press the button twice within 1.5 seconds; the next engine map is displayed
in negative against a black background. To select this engine map, press the
starter button within 1.5 seconds. Otherwise, the next engine map in the se-
quence will be displayed in negative against a black background. When the
desired map is shown, press the starter button and the desired map will be
displayed normally. In any case, do not "open" the throttle during this oper-
ation. If the throttle is opened, the activation process for the new engine map
by the ECU is interrupted (the map symbol is displayed normally and flashing)
until the throttle is closed again, allowing the ECU to complete the procedure.
CAUTION
IF THE THROTTLE IS OPENED WHILE A NEW MAP IS DISPLAYED IN NEGATIVE
AGAINST A BLACK BACKGROUND (INDICATING THAT IT IS STILL BEING AC-
TIVATED BY THE ECU), THE NEW MAP SELECTED WILL START TO FLASH
(DISPLAYED NORMALLY) BUT WILL NOT BE EFFECTIVELY APPLIED UNTIL
THE THROTTLE IS RELEASED AGAIN.
