Title: Timing pull problem Post by: enn on December 10, 2019, 01:32:09 AM Hello Guys,
From the beginning when I made an convertion from narrowband to wideband I have some problems with the ignition (I suppose it's not normal behavior). It pulls timming at low load and I can't be sure what causes it - it looks randomly a bit for me. Even when the car is idling and I softly but periodically press the gas pedal - You can see it at the end of log. I was working on several different bins and effect was similar, now I have flashed stock 4B0 906 018DC just with deleted sai, second o2, vvt and n249 (waiting for new valve so i it's temporary) and corrected for bigger injectors. Engine is rebuilded, everything is stock except of DP and bigger injectors. I changed knock sensors to new one and retorqued them to 20nm. I tried gasoline from different station as well but i though that stock flash should be more tolerant.. So, what can cause this behavior? -IAT -FPR -Gasoline Quality -Bad knocksensors or wiring -Mechanical problem with engine? -Injectors not corrected properly? I need some advice because i don't know what should i look next |
