I have an autometer A/F gauge in my car, open loop would be when my "rich" led's stay lit continuously, Correct? Beings it is no longer correcting itself. I noticed this at about 4in. hg. or less. Sound about right, and figured my shift point at about 2400-2500 rpms.
If this is what I am after I have been doing
Greatly the opposite. High vacuum and low shifts.
