The car is audi A4 B6 BEX engine, everything stock. I want to add little power in low RPM, but only the first run is good, after that the LDRXNZK table is used for load. What can cause this? I use 95 octane fuel

yes, you should add fuel or pull timing or both.

I will take some readings to try figure it out. I know how ingition works, i tuned 2 and 4 stroke motorcycles with 2D or 3D map, but still don't know how ME7 detemine what ignition map will use okey I add fuel, and looks like now situation is better But look this even if I don't have knock, rlmax(and rlsol) doesen't follow rlmx(LDRXN), later it follow ldrlts (KFLHBN) and that is okay, but in low RPM there is a problem here again have drop to LDRXNZK at 5250 RPM Is wkmr(avg ingition retard control) showing me that ECU fights against knocking all time?

6 deg avg retard and "you don't have knock"?
If Bosch didn't make knock control as good as it is and didn't pull boost/dump fuel that engine would've been blown up by now.
WTF have you done with the timing? +10 deg to entire map?

I mean in that region at 2000 rpm, but never mind. Looks like I have serious problem with engine. No i didn't touch timing at all And I have retard even at stock map. Last night I fill a fuel at different gas station, that didn't make any difference. Put octane booster, still no difference Bad or loosen knock sensor maybe? Wrong spark plug heat number?

Engine wise, valvetrain or fuel system damage. Like prj said stock engine stock ecu doesnt matter, they do not pull 6 avg knock correction unless there is something wrong with the engine physically.
