Motronic M 2.8.1 System Modification F7:
PROGRAMMING
INIT. CODING
Note:
If a new control unit is installed in a vehicle, or a control
unit from one vehicle is installed in another vehicle, the control unit must be
reprogrammed (TECH 1 function F0: RESET). For this, pay close attention to
the following notes, as otherwise the idle speed setting of the engine may be
modified to beyond the permitted limits.
In the future, it will be possible to select other
characteristic curves in the control unit for firing angle, fuel injection and
idle speed by selecting certain codes during programming (F1: CHANGE), and thus
improve the performance characteristics of the vehicle. This is done in a
similar fashion as previously with different coloured octane number plugs.
More detailed information on this will be published in the
relevant "Technical Information Bulletins TI".
Before the publication of the above mentioned
"Technical Information Bulletins TI", this function should not be
used.
If, however, a workshop should experiment with these
functions without the requisite information, please note that this will lead
to changes in the idle speed adjustment.

At present, the OMEGA - B with the X 30 XE is equipped with
the following control unit:

If the question is answered with "YES", the
following sub - menu appears in TECH 1.

F0: RESET
F1: CHANGE

Selection of the menu item F0: RESET programs the control
unit with the basic application.
Note that, among other adjustments, this resets the idle
speed to its basic values. Therefore, if the
F0: RESET function is used for an already programmed
control unit or adjusted engine, then call up the following TECH 1
function and make / check the relevant adjustment:

By selecting menu item F1: CHANGE, it is possible to select
other characteristic curves in the control unit for
firing angle, fuel injection and idle speed by selecting
certain codes during programming (F1: CHANGE) and
thus improve the performance characteristics of the
vehicle. This is done in a similar fashion as previously with different
