Yeah, I tried to avoid the "log everything" mentality, but I do need to record the other standard ones you sent. I'm curious what's going on with the vane actuation- when I had the Banks unit plugged in, it's mostly at 100%, and seldom goes below 90, but that's just anecdotal. For now I want to see if they'll send a tune that seems to solve the low rail pressure issue, and maybe answer whether it's hardware or software.Those EGTs are low, I think stock setting is 850C and it's safe to run ~935C in most cases.
Fuel mg/st dropping could be from a number of things, but from your logs it is not from EGT unless they have the limiter lowered for some reason. Could be lowering because of boost request/actual, didn't see that metric in any of the logs.
I typically would do a log of each, the VNT, Rail, EGT, and AFR files.
Though now just using two files with I believe 8 channels viewed as it's enough for @Xtremefunky to make good adjustments.
Also, no need to keep logging if it's all on the same ECU file. Would wait for an updated one to see if anything changes in the data or your seat feel.
The only reason I wondered if there was a gradual reduction in EGT programmed in is that most turbine materials have a margin of transient operation where they can still operate safely for a short period- I operate turbine engines at work, and we have limits like, normally limited to 895C but can operate up to 915 for 5 minutes or 925 for 2min. But operating at the perscribed limits still reduces blade life, and I could see similar material limits applying to a centrifugal turbine.
