VE looks ballpark, but is very rough... I smoothed it, please try attached.

I pretty much has the same set up. I'm using a ls6 intake with ls1 injectors and wondering if its okay to just copy and pasted injector information from a 1999 camaro. I Also using maf from a 2010 camaro. Did do some logging but not sure if my maf and injector are set properly.Attachment 20133

Yes, copy injector tables.

Is your FPR un-referenced (i.e. no hose connection to intakr manifold)...? If un-referenced, then injector tables are ok, otherwise they need a minor edit.

You will need to do MAF correction using wideband (because MAF and associated plumbing are different).

You will also need to do VE correction.

Maf correction was done using a wideband. If I have to past and multiply the average cell value which is 1 I assume that it is correct. I'm using return fuel system with no vacuum reference.

Thanks, I will try it this afternoon!

I log data and my fuel is rich. Sudden increase in TPS retard timing and some knock. If i decrease the #'s in VE table should that add more or take it away?

First part of Data Log the wideband wasLog_0101.efi not connected.

[joecar]

Increasing values in VE table will add more air which adds more fuel.

Are you getting a MAF DTC...?

[joecar]

Also, you should set these:
- set B3801 to disable.
- set B4206 to disable.
- C6001 P0101,P0102,P0103 to A:1-Trip or to Non-Emissions.

Make sure you get a MAF DTC, if you're not then also set these:
- set C2901 to 1.
- set C2903 to 1.

Well, I programmed the tune into my PCM and it ran the same. So I did a compression test while it was hot, with throttle body wide open and each cylinder was between 123-131 PSI. ...Edit.. Which after reading about it must be relatively normal with a cam. I'm guessing the intake valve closes later and causes a little lower compression.

I'm getting the MAF DTC now. I adjust the AFR and the car performance improve. It was running lean. Now I'm trying to iron out AFR for everyday driving.

Thanks for the advice, I'm opening to any suggestion.
