I always advise if it gets too overwhelming at first..Just do the MAF Calibration (with LTFTBENS) first..Its really simple. (Once you know how to make the MAP).
From there it is easy to figure out your VE Table..

So I can follow these directions to get my LTFTs corrected?

No, thats not my method. Mine is :http://forum.efilive.com/showthread....tire-VE-Table.
If you select those Pids, make the MAF SELBEN Table (B5001), then you log your LTFTBENS VS MAF Frequency. The Tutorial really helps..there is no other way to explain it..every step is there. Just give it a try..
Only the portions of the AF and VE tables where CL was present (i.e. where LTFT's were trimming in closed loop).
The one log gives you two things:
- MAF correction multiplier (i.e. the existing MAF is corrected);
- VE absolute value (i.e. a new VE is calculated from the corrected MAF).
If you can do the MAF part of the tutorial, the VE part is right there next to it (but in a different map).
With NBO2 only (i.e no wideband) you can only do that for CL (non-PE).
With a wideband you can also do that for OL/WOT/PE.
Mikey, near the end of the CALC.VET Tutorial, I included a method that shows you exactly what you need to do if you do not have a wideband.
So, yes you can do it without a wideband..I show an example of how you can do exactly what Joecar is saying..
From Tutorial..
II. CALC.VE Closed-Loop Tuning Only
NarrowBand Tuning (No Wideband)
For users who wish to Tune with only the Factory NarrowBands (NB) and have no Wideband available,
CALC.VE can be used for the Closed-Loop Trim portion of the Tune only.
1.Select the same PIDS, MAPS, and Data Filters, as indicated for CALC.VET. Perform Identical Logging
and Update Calibrations procedures as indicated for CALC.VET.
2. In Addition apply the following Data Filter to display Closed-Loop Tuning only.
I;m going through the tutorial now. I added the pids.txt file and see them in the PIDS section of the scan tool. I have a 98 PCM and some of the PIDS are grayed out with an X. Then I click to select, it says PID is not valid, select anyway?
an example is GM.DYNCYL_DMA which is GM.DYNCYLAIR_DMA on my PCM. Should I select it anyway? Or do I need to go into the new PIDS file and make sure the PID names match.
After right clicking and looking at "more info", I see the PID equation has dependencies. So I will go through the tutorial and select all od the PIDS as listed. If needed, I will try the Validate PID function.
