I am finishing up a 6.0L L96 swap into a 2013 Tahoe, 5.3 LMG. The truck runs under light throttle, but I am running into a P0606 code and immediate limp mode during acceleration transitions around 60–70% throttle.
We did a segment swap, but I believe the background Electronic Throttle Control (ETC) parameters or Virtual Torque models are still miscalculating based on the old 5.3L numbers.
I am trying to run a side-by-side comparison on my home PC using the free version of EFI Live V8 to find the specific calculation differences and help my tuner clean up the file.
Does anyone happen to have a completely stock 2013 Chevrolet Suburban or Yukon XL 2500 (6.0L L96) E38 .ctz tune file saved in their repository that they could share?
EDIT: OS is 12653674. (both the original Tahoe e38 and the 2013 Yukon XL 2500 donor file) Yukon XL VIN: 1GKW2REG3DR255469
Thank you in advance for any help or guidance!
