Fuel System/Engine Management
Engine Management Adaption
General Information
The engine management system fitted to this model is
adaptive. This means that the system is able to learn
about new or changing operating conditions and
continuously adapt itself without needing to constantly
make major adjustments from a fixed baseline setting.
Adaptive changes can become necessary because of
changing rider behavior, changes in the region in which
the bike is operated (i.e. operation at high altitude where it
was previously used at sea level) or because a new part
may have been fitted which has slightly different
characteristics to the old part. All adaptive changes are
automatic and require no intervention by rider or dealer.
Adaption Status
To see if a motorcycle has fully adapted, a facility named
'ADAPTION STATUS' is provided on the diagnostic tool.
The following adaption details can be examined:

Closed throttle position reference

Terminology
Where the term 'status' is used, this indicates how far the
present operating parameter is from the stored (baseline)
value. The nearer these figures are to zero the better as it
indicates the motorcycle has adapted to its current
operating conditions.
The term 'range' indicates how much (in percentage
terms) of the adjustment range has been used to reach
the current operating status.
Typical Values
In a correctly adapted motorcycle, the following will be
typical:

100
and -100%
Oxygen sensor adaption status (off 0%
+/-
10%

and -100%
Oxygen sensor adaption status 0%
+/-

(idle)
Oxygen sensor adaption range Between

(idle)
and -100%
Forcing adaption to take place
If the read out indicates that the motorcycle is not
adapted, the following will force the system to make
adaptions:
1.
Ensure the engine is cold.
2. WITHOUT TOUCHING THE THROTILE, start the
engine and allow it to warm up until the cooling fan
comes on.
3. Leave the engine to idle for a further 12 minutes.
Note:
• As
an alternative to the above process, connect
the diagnostic tool, scroll to ADJUST TUNE and
select RESET ADAPTIONS. This will force a fast
adaption routine to take place in around S
seconds. For this to happen, the engine MUST
be running, it must be at normal operating
temperature and In closed loop control mode.
Under any other conditions fast adaptlon will
not take place and may cause default values to
be loaded, which may then require a normal 12
minute adaption routine to be run.
Fault Indications
If 'range' figures at 100% are seen, then the adjustment
has reached maximum indicating a mechanical fault exists
on the motorcycle. This can be due to a number of faults
but the most likely causes will be low/high fuel pressure,
faulty injectors or air leaks at the throttle bodies or airbox.
In these circumstances, locate and rectify the fault, use the
RESET ADAPTIONS facility on the diagnostic tool (found
under the adjust tune menu) and begin the adaption
process described above.
