You logged only 3-4 relevant parameters or so, but from how this looks it seems that your primary O2 sensor is not working.

Load this preset (Dashboard -> Presets -> Import -> then load): https://www.dropbox.com/s/aoqz8qpw3bg9s ... vtpre?dl=0
On your dashboard set the desired AFR and Actual AFR to AFR gas instead of lambda.

The map in question is high load 98 octane eu with pop and crackle
The Actual AFR is mostly consistant which means my o2 sensor is not working .

Exactly. You need to replace it and fix that problem and then take it from there. At this point I'd say to use your car only with half throttle maximum, avoid boost. The fueling will follow the MAF calibration but without proper monitoring there is no way of knowing if you have other leaks on the intake side or not, and if you have vacuum leaks you could be running your car pretty lean and ruin the engine.

Is that the primary o2 before the car or after the cat?

Yep, it's not the first time this happens. These ECUs tend to give 0 full fucks about a lot of things: O2 sensors, spark plugs, oil pressure, and so on.

The one before the cat, that one you can see after the turbo heat shield in the engine bay. So the more expensive one :)
You can get the OEM or an NGK/NTK equivalent. You may find parts that are listed as equivalents from other vendors, do NOT get anything else than the OEM or NGK/NTK.

Until then you have plenty of time to keep spraying the current one with penetrating spray - that if you're not using the car any more. It will give you (or your mechanic) a hard time to take out.
