Nö, ich fahre nicht mit einer DME 3.3 ...

Gerade kam ein Verweis auf die
DME 1.1_1.3.

Dort steht zur Adaptivfunktion der DME:
... As the engine or its components wear, the ECU reacts to new circumstances by adopting the
changed values as a correction to the basic Map.
When the
adaptive map is used in conjunction with the OS, Motronic is able to respond much more quickly and retain tighter control over the changing gases in the exhaust system. During
closed loop operation the basic injection value is determined by the values stored in the map for a specific rpm and load. If the basic injection value causes exhaust emissions outside of the Lambda value (ie 0.98 to 1.04 AFR) the mixture would be too rich or too lean and the OS would signal Motronic which in turn will correct the mixture. However, this response takes a little time and so
Motronic learns a correction value and adds this 'Adaptive' values to the basic map. From now on, under most operating conditions, the emissions will be very close to Lambda and so, after reference to the OS signal, the ECU will only need to make small corrections to keep it that way.
Adaption and correction of the map occurs during the following engine operations.
CFSV operation
ISCV operation
Idle mixture adjustment
part load mixture adjustment
Operation of the CFSV introduces a combustible mixture to the engine that is compensated for by the fuel evaporation adaptive correction values after detection by the OS.
Demzufolge gabs die besprochenen Gemischadaptionen schon 1988 (ja selbst 1987) in meinem E24 mit Kat und M30B35-Motor!
