Note:
Before adjusting the idle speed and thus reprogramming the
fixed values, it is useful if the amount that the engine speed is going to be
increased or decreased is known, as once adjustment is completed,
communication is broken off and has to be re - established from scratch.
If the newly programmed idle speed does not then suit the requirements, the
whole procedure has to be repeated.
It is simpler to first establish the desired idle speed
increase or decrease using the "engine speed" test described in
"F8: ECU control", and then program this fixed value using the
adjustment procedure described below.
Ignition ON
Engine OFF
Press key F 6 in the main menu, select the
desired test using the arrow keys and confirm with YES. Follow the
instructions in the TECH 1 display.
Note:
The idle speed can be changed using the arrow keys:
· Arrow key up:
engine speed increases in steps of 50, 100, 150 rpm
· Arrow key down;
offset can be reduced again in steps of 50
The set idle speed is confirmed with "ENTER".
When the ignition is switched off and on again after
programming is completed, the new idle speed is stored in the EEPROM.
