Audi S3, more or less stock hardware,tuned to aprox 250-260 HP, don't have EGT sensor in orignal as I can see
Problem is in one moment req lambda go really low, and I can't figure why?
Calculed EGT are under 800 C°
There is no knock
IAT is under 40 C°

Only thing i dissable is CAT control beacuse car don't have it

What can cause this, this is first time I see so low req lambda

After looking in FR i assume ATR is problem, will log today and see what is happening

CATR was problem, I zero it and now it follow LAMFA,

But there is other thing strange on this car
Intake temp over 50°
Fuel 100 RON
Boost 1.2 bar at 6000 RPM
Ignition angle 22°

And there is no knock? How is that possible?
