When you connect the scantool to the vehicle, do Info->Validate PIDs; you may have to do File->Enter VIN and File->Select Controller also.

If you're going to do AutoVE (VE enabled, MAF disabled, CL/Trims disabled, wideband only) then make these maps:
- CALC.WO2BEN map matching VE table (RPM x MAP),
- CALC.MAFT map matching MAF table (1 x MAFFREQ) if your OS supports the pid GM.VETABLE_DMA.
If you're going to do AutoMAF (VE disabled, MAF enabled, CL/Trims disabled, wideband only) then make these maps:

- CALC.VET map matching VE table (RPM x MAP).
So another thing I am wondering is, how do I verify that my MAF frequencies are spot on? Meaning that hopefully it was not tampered with before I bought the vehicle? Or does this not matter?
You would do AutoMAF to correct the MAF using wideband correction.
Hey guys! Yes I am finally getting around to having some free time to drive my car although its 100 degrees out here. I honestly have no idea where I went wrong, as nothing will datalog? After re-reading the post, I think i may have not been logging the correct things. Can you take a look? Attached are my log, and my current tune. I did notice its still running about as rich as prior even in this intense heat. Running at about 9.8 on my wideband, I did just calibrate it as well.
Can you post screenshots of your AutoMAF BEN map...
I'll look at your files later tonite.
Well, I guess thats one of the problems! I just looked at it again and its a SELBEN? MAFFREQ for the rows and RPM for the columns but that doesnt even make sense as it goes from 15 to 105. Everything logged in the 105 column as well. Also, when i tried to validate my PID's from the Calc.VET the one it keeps giving me an error on with an X through it is Dynamic air temperature. I also have another logged graph and its VET average, with RPM on the rows and MAP for the columns. Everything it logged showed up as 0's.
I also couldnt do a screen shot, not quite sure how to do that.
On your keyboard hit 'Print Screen' when you have the screen up you want to show as a picture.
Then open MS Paint from your Windows programs. Start>All Programs>Accessories>Paint.
Then Paste on there and save the image under a name u want it to be.
Now u have a screen shot u can show here
Post a screenshot and also your current calc_pids.txt file...
Does your PCM/OS support the pid DYNAIRTMP_DMA...? If not, the Calc.VET tutorial thread explains how to use your B4901 table to make a lookup calc pid for it... (I can show you how).
