Bought EFILive V1 from Blackbear and did some scanning on the way home from work just to play and get the hang of things. I noticed that in 6th at low RPM (~1700) and higher TP (40-60%) I could set off some KR. I couldn't get it to do it consistently. I got up to 8 deg of KR.

Tune is a mail order from Calspeed for the T56 swap in my Silverado 5.3L, stock heads and LS1 cam. Only thing that has be changed since is the addition of a 212/212 114LSA cam and unported 799 heads. No tune has been done since the heads and cam.

Should I be worried? Could it be false knock? I tried to listen but it's hard to hear anything other the sound of the exhaust and other misc noises. I did once here a "tink" sound and got some KR immediately.

Here's a snap shot of the log. I was on the highway varying TP to get some KR.

Thats really hard to read. Could be anything. post a log file.

Log is attached. Not sure if it has all of the data you might be interested in. I only switched on a handful of PIDs. Still new to this.

O2 sensors look like they are old worn out.

Why do you think that? They are about 1 year old with 10k on them, came new from Delphi.

They're not ranging/swinging sufficiently, they should reach above 700mV (even above 800mV), and they should swing more consistently...

the trims that are added should have them swinging/ranging correctly and consistently, but they're not.

joecar

You're getting knock due to being lean, especially since PE is not enabling sufficiently early (look at AFR waveform).

Yes, I noticed the AFR doesn't drop until around 90% TP.

The bank 1 average 491 mV and bank 2 was 514 mV, excluding the data from warm up. Is this difference okay?

Thanks for the help!

Yup, tune is off a good bit.

Tune needs some major tweaks. Email me at jessebubb@yahoo dot com and I can make the changes I think it needs. send the tune file, and send me that log all in one email explaining what is wrong.
