Controller Update; Diagnostics And Service; Diagnostics (Test Actuators) - AC STAG-4 QBOX BASIC User Manual

 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.
Incorrect setting of the Reversed STFT will cause an abrupt gas pulse correction
that prevents from further driving.
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 2.19).

2.24. Controller update

To update the controller, connect it to the diagnostic software and turn the engine off. Select "Tools" -
"Devices update" from the main menu. All available devices are automatically found. The "Devices
update" window will pop up. The "Devices Parameters" window shows the information on current
controller firmware version. The "Available updates" window includes a list of updates available for the
connected controller. Loading an update not included in the program directory requires clicking "Read
update" and selecting the update file. Loaded update should be included in the list of available
updates. Click "Update" once the update file has been selected from the list. When the progress bar
reaches 100%, the controller will disconnect and then re-connect. The new version number should
appear at the bottom of the screen and should reflect the version number of the update file.
Should the update go wrong the update window will be opened automatically upon connecting with the
controller. Perform the update procedure again.
