Note:
In this mode, it is possible to
reset the above mentioned engine learn parameters using the arrow keys, i. e.
to set them to 128 steps.
The learn parameters indicate
the short - term and long - term behaviour of the idle speed
adjuster control circuit. If a fault occurs in this circuit, these values
taper off upwards or downwards.
If the fault in the idle speed
adjuster control circuit is eliminated in the workshop, the learn parameters
return to the normal value of 128 steps. This process may however take
several minutes.

Note:
For this reason, it is possible
to reset the parameters directly to the normal value of 128 steps using
this TECH 1 mode. The engine should then still be run for some time
to check that the idle speed adjuster control circuit has been correctly
repaired.
The reset is triggered by the
ARROW UP key. In addition, the various data list parameters can be
displayed via the YES and NO keys. Key F9 can be used to store
data as in the snapshot mode.
