Data Log questions

[4everRS]

Ok guys, here is a brief log of recent pulls. My question is about O2 voltages. As you can see, I am off between banks by .03 to .05 volts between banks. What is the cause?

she looks like shes running good to me..

The hypochondriac in me is obsessing to know the difference. I looked at some of MaxRS6's logs from a while back and they are nearly dead on between banks. I am wondering if I have a vacuum leak, or something going on.

Thanks though, check out the timing!! I put some 100oct in tank recently.

hmmmm....interesting, when I got my beast back after engine work, I was coming across some funky voltage readings, passenger side was leaning out a little....I have since installed the innovate wideband, LC-1 with gauge, just starting using since figuring out my grounding bug. I attempted to WOT this am and never read over 12...I think, converts to .815. Only a maiden run, but at least i know I should be a touch rich @ WOT. I want to screw around a little with device, and do some logging...i think i can datalog...once i do i will post up.....
I only share because I was going nuts prior really worried about a lean condition(do I need bigger injectors, YES...but at a later date)
