MAF tuning help

[billybrun]

Newbie here, so don't yell to much...

I'm in the middle of my first tune. I followed swingtan's guide for the VVE. Now, i'm working on the MAF. I think I'm going in the right direction, but can't figure out why the WB AFRs don't follow commanded AFRs upon start up. Also, sometimes it's dead on, but it drifts up and down.
Here is a log of idle and revving up.
One more thing sometimes the RPMs like to fall below commanded idle before recovering. It's an LS7 with a mild cam (11 degrees of overlap), worked and milled heads (11.8 SCR), stock intake and exhaust.
Help is appreciated, thanks.

Now I'm thinking I didn't dial the VVE as best as possible. Could the VVE be affecting my MAF tuning? How do I disable the VVE table from affecting the MAF? Thanks.

Admin please close this. I went back to dial the B1213 and VVE better. I'll be back to the MAF soon.

When you do the MAF, you have to set the dynamic airflow threshold low to force exclusive MAF.
