Hi guys!
I changed my stock GS-t injectors to FIC 850s, and set my fuel settings based on ECMWiki (Global: -47,1%, deadtime: 330µsec), then started the car up. The WBFactor was off the charts, so I started adjusting my MafComp table to that, and then went for a short drive to line up the lower hertz region. I only realized after, that my AirflowPerRev went up too on idling (now it at .36).
So the issue is, that when I lower the 50 Hz region at the MAFComp table, then the WBfactor goes high, but If I line up the WBfactor, then the AirflowPerRev is too high. (I attached a log where I am gradually lowering the MAFcomp while idling, and you can see the WBFactor reaches ~+45% when I can finally see .25-26 Airflow which is still a bit too high. I tried the same with adjusting the deadtimes, (I went from 250 all the way to 500, but i couldn't lower the AirflowPerRev with that too much). What else should I look out for? Is there something else I need to start to adjust, so I can have both good at the same time?
Btw.: I have a Stock MAF, Stock Engine (with Evo 8 pistons), Stock turbo. I had the AirFlow at .24-25 before the FIC 850s, that's the only thing that changed.
Thanks for the help in advance!!
