Full Throttle Option - A.E.B. AEB215 Manuel D'utilisation

OPTIONAL CONFIGURATIONS
FULL THROTTLE OPTION (Fig. 53)
By enabling this function, it is possible to set a position that the
stepper motor must reach during full throttle operation. This is useful
for those engines for which the normal carburetion in this condition
can either be too rich or too lean.
NOTE: this function is normally disengaged since the basic fuel
management strategy of the LEONARDO is able to ensure a
correct operation in the majority of cases.
When the full throttle option is enabled, the following parameters
must be specified:
ACTUATOR POSITION DURING FULL THROTTLE
(Fig. 54)
This is the position that the stepper motor must reach during full
throttle.
To correctly establish the value to be entered, the performance of a
road test is recommended with the tester connected to the LEONARDO.
Establish at what position the stepper motor must be in order to
achieve a stoichiometric condition which is indicated when the display
bar of the Oxygen Sensor flashes alternately on RICH and LEAN.
After this value has been entered, repeat the road test, and increase/
decrease the value if necessary.
FULL THROTTLE TPS (Fig. 55)
This value establishes the T.P.S. threshold that engages the "FULL
THROTTLE TPS", that is, the T.P.S. voltage beyond which the LEONARDO
brings the stepper motor to the predetermined full throttle
position.
