Hi guys. My problem is rich idle, when i start the car everything is fine till it reaches some temperature. Lambda is constantly dropping till it reaches 0.727, stft are -25% and stays there. Wot and mid load requests are fine, only problem is on low loads and idle. On previous oem 320 injectors everything was fine, now i switched them to 630 deka's and i'm trying to get them idle properly.
I was playing with tvub, when 14v value is 0.45, lambda stays around 1 and stft are operating in +/- 7% from 0. But on that tvub setting car is idling rough and misfiring. Starts idling smooth around 0.65 14v value, but then the rich idle problem goes in. Tried turning down krkte on ridicoulus value 0.022. Engine barely starts and revs up, but when it reaches some temperature lambda is oscilating around 1 and on idle everything is fine. Any advices???
