LTFT works great thanks to gremlin. But the engine works badly, I forgot about EGR fueling corrections. ECU thinks that egr works and is open at low loads, so it decrease fuel trim (less o2 in the combustion chamber while egr opened) and LTFT is 25% and STFT ~20%
Correction is not sufficient at decreasing load and i have unstable idle RPM with AFR ~16.
I don't know if EGR has typical map or one calculated parameter by MAP but in Funktionsrahmen i found parameters which should help.
Can you find this parameters? Thanks, because you really helped me a lot. If I change AGRRMAX and CWMDBAS to 0, this should be professional EGR off with all works great.
