Well hopefully theres some change for the good lol. little tip in kspark retard on warmup maybe normal

Ok log this one with more varied driving like you did with MAF.
tried to get into the throttle hard on back roads lol. also i fixed my wideband offset as it was reading .7 below on the logs than what it showed on guage.

It was? What is your formula then?
*2.3750+9.8125
Been trying to fine tune it but it’s jumps around so much try to get it averaged out. on the maf runs like it was 14.7 around there pretty much untill PE and in cold of course

That's the formula I've been using, too. Narrowbands confirm that.
Oh ok, so it’s different on your end than what I have been seeing? So when I log your able to change the maths around just not add Pids J haven’t added right?
What's your idle fuel pressure? It should be around 50.5psi.
Alright just trying to figure out why VE is so high. Thought maybe the pressure was regulated low. The other thing would be displacement. A lot of ATK engines are overbored, but nobody is boring out an LQ4 to 6.8L.
Yeah it is 30 over I’ll double check base psi in morning but pretty sure it’s still 58. Which makes me still wonder if something internal could cause a High VE table
Nothing internal is going to make it breathe that well. Thing is it's not that efficient at all. Low fuel pressure, incorrect injector data for the injectors, displacement, or high ethanol content can throw this off.
It's no big deal I can correct the timing. Just pointing out that you should verify fuel pressure. 58psi is with vacuum line disconnected or at WOT.
Yeah we’ll I did notice VE was still lean was hoping to see it go way rich like mentioned. I wonder if this aeromotive regulator is just not good it’s the second one I got, it does drop off after primed, but I know it’s a return style so that’s normal. Maybe Engine shop fucked timing up could that cause inflated Ve?
No I don't think the machine shop did anything wrong in that regard. As far as aluminum in your oil then maybe, but nothing to do with VE.
Try to keep an eye on pressure during WOT.
Ok, I wish I could log this gauge, lot of times been busy watching knock and wideband to see if I’m safe
fuel pressure is holding. i know the regulator when keys off doesn't hold pressure because its a return style.

You checking whether pressure holds when it shut off at 5:21 right?
