Have you looked at the AutoVE tutorial? You can also make a map inside the scan tool and create a map of the LTFT values to edit the VE table.

they disable LTFT,STFT,DFCO,CFCO,DOD,VE table
and use MAF to correct LTFT
what do you think guys
and at EFIlive what Pid,s use to log LTFT to adjust MAF table
If you have the table pretty good with the wideband doing he autove, what I did was re-enable short and long term fuel trims. Editing the VE table won't fix MAF calibration, and that was a bad assumption on my part, since a very large percentage of this forum is related to Speed Density (SD tuning). There is a AutoMAF tutorial very similar floating around on these forums.

Here's where I got my information on the MAF.

I kind of poorly worded it above, but I will try to give a more step by step directions. I'm in Korea, so I don't have a vehicle or my flashscan in front of me, so give me a break.
Run the AutoVE with a wideband and with the MAF unplugged.
I then created a MAP of STFT/Cell numbers, and did a paste/multiply over the VE table to further smooth it out. I repeated this procedure with the LTFT/Cell tables.
I plugged the MAF back in and disabled the LTFT/STFT to calibrate the MAF.

Also, adding to nevinsb's post, while calibrating the MAF you have to disable VE.

Anyong haseo!
OK! Are you still running the MAF? If so then try raising the MAF curve 10% (for example) where you are seeing the LTFT's add a lot of fuel. (this is a quick fix - more effective with stock cam with MAF in stock position).
If you are not running the MAF (it is unplugged) then you will need to increase the VVE table where you are seeing LTFT's add the fuel. Try 5% at a time until the LTFT's head back toward zero. Or try increasing the whole table 2 or 3% at a time to see how your LTFT's move. If you are tuning the VVE, best to follow the tutorial/Auto VE process etc
Do you have a wideband O2?
nevinsb: Thanks u help me with MAF Calibration
gmh308: yeah that what i want quick fix
i use LM-1 wideband
bth i fix my LTFT
guys do u have like me when stop MAF and go SD transmission Change very very hard at part throttle!!!
i have friend he take off maf and go WOT and the transmission crash when change 2-3!!!
