Yeah, just about burnt that tank up so I will be filling up soon.This log looks great btwIf you can, get some on E20 and E30ish blends too!
Yeah, I was noticing that as well. It is my understanding that the DME manipulates this value under certain conditions. Certainly, if the DTC is on it will effect the throttle position.
Are these throttle movements concerning? And if so is it because of their magnitude or their timing?

DTC is fully disabled in all of my logs. ( I hold down the DTC button for a number of seconds until the circle-arrow,-triangle(!) displays on the dash)
Could this be my transmission limiting torque? (hello, excuse to buy xhp)
Your boost is a few psi over target- could that be causing the throttle closures, especially from 5000 rpms on.
I was more wondering why timing dropped from 9 to 3 around 4500 and then climbed back, but there was no timing correction on cylinder 1.

If you want to understand throttle behavior, load up a stock map, do couple of pulls and then compare the logs with a non stock map. Im pretty sure you will fine a custom map or OTS map will be much more forgiving with throttle behavior than stock IMO.
In other words throttle closure is pretty much an elaborate and normal function of the DME. Use the stock as example to determine what is good and what is bad throttle closure. There is a lot more to it than this but its a start.

Hows this log look? Roughly e48 fuel.

It is not from the trans, it is due to boost being over target a bit. I will fwd these along to Ken (@WedgePerformance ) for a look, he may need to make a few map tweaks. Can you give some more details on your mods, and what map you picked for your pump map?
DME will pull timing for overboost as well, this does not show as a cylinder correction as that ram variable is only from the knock control system.
Got to see this work for real yesterday. Was running at E80 and took the Z into Chicago. Not enough in the tank to get back home so I had to add some 93Oct.
Watched the E content go down to E40, watched the interpolation go down.... it all seemed to work perfectly.
Ha... south side of Chicago. Gotta get gas before the toll road, no choice.
I see a BP station with literally 12 or so Chicago PD SUVs all about the lot. Pull in with the top down, got all the business clothes on. Drive around the pumps and a lot of locals are hanging out. First thing I hear.... "Damn! this dude in the wrong hood" More a tone of concern than contempt.
