Looks like your WMI cut out creating a lean spot, you see it come on and trims fall and then the trims starts rising.

Do you have an intercooler?

Stock intercooler, I don't believe the WM cuts I can hear it pumping, it causes the engine to sound differently. I'll try pulling a couple more. This might have been on a S bend ramp.

how does this log look? Is the timing correction anything to worry about?

when does JB4 increase boost for a given rpm? Only at WOT or does it start at 50% throttle opening or 10%?
I mean if I set 4 psi extra at 4000 rpm will I get those only at WOT and before that it's like oem boost or will I already get 4 extra PSI at 10% throttle opening.
Or is their some kind of algorithm that will give for exemple 0.5 psi at 20% throttle then 2psI at 50% throttle and finally 4PSI at 100% throttle?
What I mean is it only 2D boost mapping ( RPM/Boost) or is their some calculation that make it 3D ( RPM/boost/% throttle opening)

This latest revision felt great!
Sending the logs to George, but we just upped the boost safety to 27 and it's the first time hes adjusted the fuel bias values.

Does it happen every pull, and at the shift? Otherwise you are kinda pushing things so some corrections is ok as long as its not long on multiple cylinders or a repeting pattern.
Its progressive and changes with software updates.
Looks good as long as the corrections after the shift is not always there, and much better AFRs then what 2019s on JB4 usually does.

Got some solid data. Back to back to back but IATs had plenty of time to come back down.

What corrections? I'm still learning the basics here.
Really? I'm happy with that then.
I really dont know how you live in vegas with all those mods and dont have an IC yet...
These timing corrections from the knock sensors.What corrections? I'm still learning the basics here.

They are for cylinder 2-4 but you most likely had some in cylinder 1 to but since JB4 only shows positive numbers and ign_1 is also used to show timing advance it will not show up when ignition is not advanced. No biggie as long as other logs are cleaner.
We should always be tuning for 0's on those values right?
Gotcha. Well, I really only sent him those two logs for this revision. I'll send him more next time, so he has a better picture. I'm dropping the ball here.
