I looked at your last log in Datamaster under a few cars and all the same but what is it? Camaro, Caprice? Looks like Auto...

Your WOT voltage did improve but at 5900 RPM your down to 12.8 volts and from 850 RPM to 3500 RPM your at 13.4-5. So maybe a belt slipping too?

Went back and read first few posts and you got a cam and 1.6 rockers, regular driving your rich, BLM should be closer to 128 and your hitting rock bottom at 108 so you need to adjust the VE tables for fuel. Is your pressure stock?

But WOT your hitting 90% Injector Duty Cycle in spots and O2 reading left stays in .9xx but right drops to .2xx and it shouldn't. Injector duty cycle should not go beyond 85% tops! Seems to be an area getting some knock too. Your running out of fuel. Or injectors are going static?

Watch your data log slow around Rec# 70 to 75 and 460. Actually watch the whole thing slow and study it. When the boxs change color it's an alarm, you can also click on View Knock Retard for another KR window. Looks like all real knock to me.
