So Im trying to monitor vf to tune with maft basic and my issue is that im getting 2.2v all the time, adjusting maft makes no difference in this.... ontop of afrs not being correct. i.e. It might be 11 afr at idle and you can change airflow signal to make it lean and still 2.2v the whole time. Ive tried a different o2 and theres no change.
SO my question on top of that is, does the vf feedback voltage come right from o2 or from the ecu itself? the vf1 pin on ecu pinout is just labeled check connector.
