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

Here you can see that drop to LDRXNZK
now i have remembered I didn't change LAMFA, it is stock, could that be a problem?

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. |
