Closed Loop is LTFT.Calculate the entire VE Table from Idle to Redline RPM in a Single Log Session:
1. Tune Both Closed-Loop and PE Mode/WOT (simultaneously)
2. Calibrate MAF
3. Eliminate Trims

It nearly died on the operating table, but I'm bringing her back.
OK somewere in this I'm missing a step or something. My VE map is in #like 82.324and 85.436 but when I go right by the new Tutorial they end up being #like 1.325 up to like 3.42 witch sound like % to me but I've gone back and redid all the maps and logs and still get them. Were am I going wrong?????

I have a question for you experts. Instead of copying and pasting the calculated VE table into the tune as is, what would you think about doing it row by row. Let's say I want to do the 1600 RPM row... I use the normal ECT and TP filters, and then also filter out data under 1500 and over 1700 RPM. I think this would give a much better representation of the 1600 RPM row.
The issue I think I'm having is that when I log data on the highway, I'm spinning around 1750 RPM, which is almost halfway between 1600 and 2000 RPM, but all of this data is going to the 1600 RPM row. So my VE at 1600 RPM is too high because it's actually representing 1750 RPM.
Or maybe make the data table with increments of 2000 RPM and do some clever interpolation to make the final VE table.
Thoughts?

Where is this Calc.vet tuning tutorial I keep reading about? There's got to be more explanation than just the few steps listed in the first post of this thread. Yes, I've read the summary notes. The problem is that I have an analog wideband and can't get the proper PIDs. I think I have all the crap taken care of in calc_pid.txt. The first post does a good job showing things for a serial WB. I've done AutoVE before and had no problems with that writeup. But now I have a 5-pin MAF and don't want to screw with the wiring so calc.vet seems like a good option. What am I missing?
Hi tinindian,
Post #1 has all the steps and explanation...
it also shows you how to handle analog wideband:
