Now is the perfect time to utilize Winlog and it's fastlogging capabilities. No need to search around in VCDS measuring blocks when all the data you need will be presented in one easily readable and user configurable single screen. Look for AFR_REQ value, if it's not fluctuating around and is staying still while car is running idle with warm engine then yes, your closed loop lambda control is off and yes, it can be switched on or off based on LOAD in the software.
Now when you look at IPW_RAW it might give you hint, why is it so. If it's anywhere near the 1.4XX region then your tuner accounted for your Deka's so at least you got stable idle. Otherwise if the closed loop is enabled, ECU will pull the AFR to 14.7 region, meaning that it will lower IPW to achieve that but these final values already fall into area where the car won't idle.
Even though wiki suggests to use Winlog 14point7, I would personally suggest to use regular Winlog from devtechnics website as time has passed and the software is now completely freeware with no nag screens anymore and there has been couple of updates since then.
