OBD target correction map
Switch on threshold
– A value that extends the range of acceptable resultant target
correction. For example, a threshold of 4% with target correction of 0% (on the map)
means the range of -4% +4% of the OBD resulting correction, within which the
adaptation procedure will not correct gas doses.
LTFT max.
– a limit, maximum trim value that the OBD autoadaptation can make.
Acquire OBD correction map
– Activation results in automatic filling of target
correction maps when driving on petrol.
Adaptation in OL
– OBD correction values are used if the engine open loop control is
applied. Activation of the option allows additional adaptation, adjusted to the status
of the open loop. In order for the function to be activated by the controller, a Lambda
probe must be connected or Lambda value must be read by the OBD2/EOBD reader.
Limitation of the OBD autoadaptation depending on engine rpm is implemented with the
“Adaptation lock” option accessible through the context menu on the MAP correction
map tab (see 2.1.5).
