Hi all. I tune a lot of GM cars and i?m starting to dip my feet into Ford?s now because I have some friends with mustangs and as I went to do some data logging this weekend but it didn?t give me an option to look at upstream O2 sensors. Only B1S2 and B2S2. Is there something I?m not seeing or that is just different with how the Ford ecu calculates fueling? And I was also curious if anyone had any channel layouts that I could use for the necessities of scanning these cars. I appreciate any help! Thanks in advance. -Jamie
