single 2nd gear WOT
Also, I have logged mibas/mizsolv mifa/misolv and miszul but I havent had the time to study how to interpret TI, could someone take a look at these variables for me and give me a rundown on what to look for and how to interpret TI?

This still not sorted? I'd of though whats his name would have impressed you with var names, program flow and a fix by now.
pm one of the mods mybe I'm beyond helping sorry buddy

FFS please don't pm anybody. Torque monitoring is likely not your problem.
What is your KFLBTS?

Computer charger died, so I won't be able to get a screen cap until next week but it's mainly 1 and tapers to .75 or so towards the bottom right side of the table.
.gif related but not my table. Tapers in the same manner. Basically the exact same.
png #1: part throttle. shows pedal pos steady and mostly static, throttle plate angle drops suddenly and so does boost. Why? this is the most direct example I can provide of what I'm feeling.
png #2: part throttle. 2nd gear is same as png #1. 3rd gear? wtf, pedal pos steady and static yet throttle plate opens significantly and thusly, boost increases.
png #3: another example of part throttle boost and throttle plate random closing. next gear is normal and fine, gear after that, random boost drop again.
png #4: Shows boost drop and DV logged. My eDV follows B_ldsua. 1 is open, 0 is closed. I had it operating under cruise conditions at the time so it was open most of the time. I tested this by turning cruise condition for DV on and off, no change in boost fluctuation so that isnt the issue, plus, you'd see a change in Bldsua where the drop occured if it was a factor. It's got something to do with something else
png #5: AFR influence during boost fluctuation evidence. 1 all the way throughout the anomaly. What would BTS have to do with this?
I am limited to old logs and what variables I can graph until I get my comp running again.
I'm not sure what other variables to compare and contrast.

There's also a bit of ignition retardation. You sure it's not TI? I could still use some help with torque intervention, torque management and load understanding and log interpretation (mibas/mizsolv mifa/misolv and miszul)....

Throttle cut is slow path intervention, not torque intervention (which generally implies timing, or fast path).
Post your log.
Or at least graph req torque and actual torque, and req boost and actual boost.

Also, im still having fueling issues. Fuel pump only primes 90% of the time on startup and that 10% is usually on cold starts or first thing in the morning. It's hard to replicate. Swapped in new fuel pump, no difference. I need to check the voltage to the pump on cold startup. Maybe replace the sending unit housing? Maybe a line is clogged(unlikely).
I should check the fuel pump wiring under the car to the ecu too.
I had injectors flow tested, new fpr, new pump, new filter. New and tested relay. Fuel rail is clean and clear i think...
Has anyone ever delt with this bullshit before?

Ok, We're back. I finally got my logging computer fixed (fingers crossed). I've logged requested torque (mifa) vs actual torque (mibas) and requested boost vs actual boost and I don't see any discrepancies. Variables taken off of this log.

I've also been running some tests. One of whichh was a leak down. Less than 10% on all cylinders. So rings and valve seats are good at least

have you measured fuel pressure at the rail with a mechanical gauge?

I am seeing pedal drop (wped_w) to zero periodically.
Bad accel pedal. Definitely seen this before.

SB_GLI, Yes. I measured fuel pressure at the rail. The results are buried in this thread somewhere. It was 100% in spec.
Nyet, those drops to 0 are gear shifts….
Am i missing a joke or sarcasm or something?
