ok no1answer but i will update this thead till i will solve my problem mby in future it will help some1, so i have brand new ngk ntk maf sensor. I make a log and car going very rich now, and i have 30 g/s more on 3k rmp (its possible that old maf was death?).  I have a question how to scale this fueilng via KRKTE or what? And how to avoid to go over 840 on EGT, just correct fueling on lambts?

This is going to be the same answer again and again in every thread.

PLEASE post some logs.

As for your vvt questions, maybe its easiest to just use eskonf (wiki).
I dont know how good a MAF from NGK is, but usually they are from bosch.

So the answer is, your old maf was dead, or your new ngk maf is not that acurate.

I did have a look into your log from june 23 and you iat is still very high.
This will cause BTS (Bauteilschutz, Part Protection) and this will reduce ignition angle.

What are your fuel trims like after you cleared dtc's and did some miles of driving?
Does it have a clean lambda1 when idling?
Have you tried to fix fkkvs?

Please add engine water temp to your next log.
Last log stops at 5000rpm?
