Do you have connected sensor ? Or egt inputs are not connected ?

Connected sensor , when i errase it and run engine the max egt shows normal . Ignition off , ignition on and the logbook still shows wrong egt .

6

When i connect second egt sensor there is no problem in logbook , no errors .

I am currently using the “Custom Air Flow Correction” feature to adjust the airflow in response to the increased load when the A/C compressor is engaged.
Have there been any changes to how this is handled since updating to version 3.068?
The idle speed does not drop to the target value even when the A/C is turned off.
Am I overlooking something? I recall it working correctly prior to the firmware update.

The log sequence is: engine start → A/C switch ON → OFF.

No modification for that.

Only armed air CLT correction added

I will check for a physical failure of the ISCV.

The issue was resolved by replacing the ISCV.
I briefly reverted to version 3.065 during the replacement, but the control transition feels smoother with the latest firmware. Everything is functioning perfectly, including the lambda control.
