Checking Engine During Idle - MV Agusta Brutale 675 Workshop Manual

CHECKING ENGINE DURING IDLE

The engine control unit is designed to adjust the torque
issued by the engine during idle.
Set up the connection between the control unit and the
diagnostic software. With the engine warm and the
fans on, in idle, in neutral, observing the following para-
meters through the diagnostic software within the rec-
ommended intervals, you are able to control the cor-
rect operation of the engine.
BRUTALE 675:
Engine rpm
Adaptive lambda check
Suction pressure
Engine load
Throttle capacity adaptability min - 1%
BRUTALE 800 - DRAGSTER 800:
Engine rpm
Adaptive lambda check
Suction pressure
Engine load
Throttle capacity adaptability min - 1%
Operation outside of the recommended intervals is a
sign that the engine is not running correctly.
If the recommended intervals are not being main-
tained, it is a good idea to proceed with the following
checks in order to find the cause that is making the
engine operate outside of the intervals provided above:
- checking, with a diagnosis, the validated system
errors;
- checking the petrol pressure and making sure the
injectors are working;
- making sure the throttle body is working correctly;
- making sure the exhaust is working correctly (cor-
rect installation, holes, leaks, the state of the cata-
lyst, etc);
- checking engine phase.
