Just for clarification - mine would only do that on a fresh fill-up with big changes in E. Either going from e10 93oct to E85 (actual e70 here) or vise versa. After 1-2 miles it would be spot-on...

My bad. I got busy with life and forgot to follow up. I built a stroker motor for this car and stopped even looking at the swings when I would make big jumps in E. Car still drove great.
I’m not sure what the owner does. He is just a neighbor and asked me to help. I’ve seen him drive the car quite a bit so I suspect he is just dealing with it.
Never got it to work, unfortunately
Solid work! Glad it is good to go now.
Not too bad of a process when you compare/copy.
Yeah, I feel your pain - I finally hit my tipping point and just kept digging.
Yeah, but what threw me off is that all of the tables I could...
Turned out the fuel level sensor was due to a sticking float. When I changed the fuel bucket and went to twin 450s, the bucket turned ever so slightly where the float was hanging up on the tank's...
I tried that, and it didn?t work.I?ve read it?s worked for some people though.
Bringing this back... I am battling with a '68 Camaro with a 2013 E38 / T42 combo.
Just like the OP, everything functions as normal when the key is on and the engine is off. I verified the ECM and...
The Max Fail change did it! Thanks again!
Also, I should learn to read table descriptions. Says it right there - if you fail the MAF, the value is the Max area?
Thanks! Just adjusted the tune. I?ll it that in the morning while my neighbors are waking up. 3.5? dump right off the turbo should sound pretty good?
Another evening of troubleshooting. No matter what I do, the TB goes to 14% directly after it fires up, causing the RPMs to drop and kills the engine. It's almost like there's a ceiling on the max TB...
Never touched that table. Maybe the previous tuner??
At any rate the TB closing to 14% no matter the RAF or SU Air does not make sense to me. I made a note to verify the MAF is failing correctly...
No matter if I max out the start-up and the minimum airflow table, the TPS goes to 14% and eventually kills the engine. I've never ran across this before and am quite baffled. You can see the spark...
Fair enough. You hit the nail on the head - I am just saying you can game the torque side of things on this gen ECM where on a Gen 5, it seems MUCH more critical and not easily gamed.
Thanks for...
See comments in red.
Can anyone help with these questions, please? Even if it is just a guess or conversation piece, it is welcome here!
Right to the point... a lot of searching, but I couldn't find anything to answer these. I'm a total newb when it comes to the 6L80E platforms.

1) Is there a general...
Thanks for the tips! Maybe I am missing something simple here too.
I've checked the board on the fuel bucket numerous times to ensure everything was contacting properly and clean. I unplugged the...
Yep, goes to show there is a lot going on in the background. I'm still baffled as to how the "Engine Diagnostic" segment kept everything from working correctly. Adding it was just my version of...

I think I corrected issue #1 by adding the auto transmission diagnostic segment to the file (not sure why this mattered).
Issue #2 fix documented here:...
Forgot to provide closure to anyone that might be having this same issue. When I did the segment swap, I never segment swapped the engine and engine diagnostic segments from an auto file. Once this...
I did something similar with my GTO; I went from a M6 to a 4L80E.
The easiest (and cheapest) way for you is to find a stock auto GTO and segment swap the engine, engine diagnostics, transmission,...
After all of the times I used the Bluecat tool, tonight I noticed a section called "Shift Lead Time". It turns out that I was actually super close with my next file based on the results from the...
