E38 VVE Dial In Guide Guidance Needed

================================================== ==========
I am looking for help with my first E38 VVE Tune.

Vehicle is a portly, 2007 Chevrolet Avalanche with the L76 6.0, 4L70E & 4.10 diff. Originally equipped with VVT & AFM, I have removed all of that with a recent engine rebuild for a GM LS3 cam (after the second AFM lifter failed in 5,000 miles, mind you). To tune the computer, I removed the AFM and VVT and copied the stock 2008 Corvette B8101 table and inserted it into the original L76 tune (same cam & heads but different intake and ever so slightly less displacement). Everything is as it should be, no codes but relatively poor performance in a few areas other than light load cruise.

This is my first attempt at tuning the E38 and I feel like I have followed every point and verified by taking notes of every single stock parameter that will be changed back after tuning.

I think that I do not have my BEN MAP properly established, but I would like a second opinion. If I were to give any feedback on Swingtan's guide, it would be that this is a seemingly critical data point and for a tutorial, it should probably be well defined instead of non-existent (Not to say that I'm not grateful for the guide or the subsequent help I'm seeking here, just merely pointing out a shortcoming of that tutorial).

Attached is the tune and my PIDs. Any advice to upload a log that is 2.48 MB??? Also, I was going to upload my BEN MAP for reference but that is an invalid file type for this forum...

I am using an AEM 30-0334 UEGO through Analog's AD1 port on the V2 for reference.

I'm open to ideas and comments.... any help/discussion would be beneficial.

Please attach your most recent log file, and your calc_pids.txt file.

[joecar]

Can you zip the log file (create compressed folder out of it ** see below), post the .zip file.

To upload your BEN map, zip it also, post the .zip.



** to zip a file, on the file's icon go rightclick->Send To->Compressed (zipped) Folder and you will see a .zip file with the same name appear on your desktop.

Thanks, Joe. I didn't think about zipping.
Here are the 4 files (1. BEN MAP, 2. TUNE, 3. LOG, 4. PID .TXT)

To further describe what is happening... I am removing low cell counts and applying my filter before performing a "Copy with Labels" in the Scan Log, then performing a "Paste and Multiply with Labels" in the Tune's B8101 table.

Here is my Graph Before the Paste:



And here is the Graph After the Paste:

[joecar]

edit your calc_pids.txt to read as follows (add the red part):

*CLC-00-110
factor             0.5           1.5       .4  "{CALC.AFR_AEM.lambda}/{SAE.LAMBDA}"

( use an editor like Notepad, i.e. not Word )

[joecar]

Do you have the pdf for your AEM wideband, I want to check the V->AFR/lambda equation.

[statesman]

How are you doing your calc.dat without logging ECT?

[joecar]

For E38/E67/E92 we take a shortcut, we use SAE.IAT for CALC.DAT (since I could not see any IAT/ECT blending tables).

[spedracr93]

Thanks, Joe. I'll update that reference in the PID file.

Do you have the pdf for your AEM wideband, I want to check the V->AFR/lambda equation.

Here's the page showing equation and table:
