From working with my 2016 Camaro SS, here's the info I've gathered on FTC definitions for gen V:
cell 0-5 Airflow based, Purge On
cell 6 Idle, Purge On
cell 7 Decel, Purge On
cell 8-13 Airflow...
Got to give another shout out to Cringer on the new tool. Also want to mention his take on using dynamic airflow as the tuning standard and not separate MAF/VVE. My methodology for tuning both was:

I'm curious about the shape of this stock VVE table from a 2016 Camaro SS M6. Does anyone have a clue why the stock open manifold switch table would have such a massive dip in VVE at 3400+ RPM and...
Quick check of the MSD pinch bolts revealed most of the outer ones 1/4 turn loose. Re-torqued and will take for a drive shortly and get another log. Probably need to revisit MAF ST trims.
Nothing unhooked that I could see on a cursory check. No breathers. Only thing I can thing of is pinch bolts on the MSD. Will check and retorque them later today and try again.
Ok, finally got a log showing the idle issue mentioned above. Rolling idle seems fine, but once stopped it continues to add more fuel to maintain idle. Trims get pretty much maxed out. Tune file used...
Starting point for that VVE table was the one given to me by my original tuner. Was always sus about it as it was much different than stock.
Went back to stock VVE. Something I learned just...
Also, if I base my filtering on the above 0-15 definitions, it cleans the logs up nicely for my needs.
Thanks for that, but I'm fairly certain based on my research it changed to only 0-15 cells for gen IV and later. So far, I found the below on this old post related to gen IV.
This line up with...
I've used google and forum searches looking for a definition of the available fuel trim cells values (PID 6310). Maybe I'm not using the right search terms, but it would be nice to have a list of the...
Closed and open were updated to the same.
In this case, trims went extremely positive. I wouldn't think it would command such a lean condition. Ethanol content has been consistent. Haven't put...
Yep. Coolant and oil temp were in normal operating range.

I'm mainly just tweaking small things here while learning gen V tuning. Thought I'd mess around with...
Curious what ever happened with this? Did you ever set a fixed cam retard and tune, specifically around VVE? I've noticed on my E92 from a 2016 Camaro that it appears VVE can only be edited at 0...
Getting things set up to dial in MAF and VVE on my 2016 Camaro SS (FBO, E85). Runs well enough, but thought I'd go through the tune myself and make sure everything is acceptable. Been studying up on...
