Yeah, I just went over it again. I don't know which version chip you have but appears you haven't fiddled with the parameters. It looks like the ECM is keeping up with the fueling but narrowband O2's like that make me nervous. I'd add fuel in the 3/4 and get those O2's up at the end of WOT blast.
One other thing....almost 3 minutes of a log....3 to 4 different WOT blasts and not one hint of knock retard ( hooray!)....but I'm accustomed to at least some knock counts in every log mine has, even if it's start-up knock counts, or burn out box knock counts. But yours has nothing,...nada,zip,zilch knock counts. Are you pretty confident the knock sensor is hooked up and working?
I'm talking about " knock counts" and not "knock retard".
I have the 5.7 street chip and no i have not adj.or fooled with any parameters and yes i'm with you on the WOT o2's i was thinking the same thing even though it's NB... and yes i am pretty confident knock sensor (i think) is fine as i am running half sunoco 93 and about 5gal 110 oct, as you see so far it's only 15lb boost at wot. fuel p. is what i am worried about since this car is hard to keep straight and look at gauges at the same time, i thought the PL logged that too... (fp) to me it look's like i need to pull fuel in 1st and add in 3@4...
