I made the two charts to line up well with their perspective settings...of course MAF for MAF and LTFT + STFT for VVE.
For VVE you will need to turn off your MAF. You don't want to unplug it because the IAT sensor is in it and that will mess with your results. So you go to ENGINE DIAG - AIRFLOW - and set MAF FREQUENCY FAIL HI to 2 (if memory serves...and it sometimes does not) and MAF FREQUENCY FAIL LOW to 1 (I think GEN3 is 1 and 0 while GEN4 is 2 and 1...). Then under ENGINE DIAG - DTC's - you'll want to go down to P0101, P0102, and P0103 and set them to MIL on FIRST error (not second). Some turn off FUEL - Power Enrich for this phase but I would just move your PE Enable MAP setting from 55 kPa up to 85 or 90 so that you will have the extra fuel if you end up needing it during your logging....but you really don't want PE coming in during this phase if you can help it. Now under ENGINE - FUEL - Cutoff,DFCO - DFCO Normal you can set the Enable temp to 493 or set Enable RPM to 8192. Now I save this tune as a VVE tune and keep it separate from the original. You can now download this one to the KIA. It might not run as smoothly now without the MAF. No big deal. This is just a temporary phase. Now I warm it up for more than 10 minutes as valve temperature and maybe even injector temp seem to affect trims on GEN4s below full operating temp. Now you can open the scanner, connect to vehicle and go over to what looks like a power button...under Engine - Fuel you will want to reset fuel trims. Then it is off for a smooth drive. I usually run around in second smoothly accelerating to a little past 4000 RPM then upshift to third and again smoothly pull up to 4000 then upshift to drive and very gradually slow back down sometimes keeping very light throttle pressure so as not to get really messy readings (tough on the brakes, smarter people use filtering to disqualify readings in this phase....maybe I will figure that out some day). After doing this for a while you get a feel for what you need to do to populate as much of the table as possible....and I suggest doing it for quite a while in order to get as accurate readings as possible. You will see how the numbers steady out as you go longer and smoother.
Then it is time to apply the numbers to the VVE table in your VVE tune. Your first run will be off by quite a bit. If the whole thing is off by 20% you can multiply your whole table by 1.2 (or -20% multi by .8) then go for another drive... The real professionals just take their carefully filtered table and multiply special in some way to apply it to the VVE table. I apply pretty much the whole thing one cell at a time blending and smoothing as I go, then blend around the edges, then click CALCULATE COEFFICIENTS, then copy the whole table and go up to the modes and open each of the modes (DODs and Manifold Switch Open) pasting into them and calculating coefficients. Then save it, load it into the KIA and go for another logging. This part is tedious but worth it.
I should mention that without the MAF functioning your trans will shift HARD. This is normal. Not sure how you hooked up those monstrous U-joints to that KIA pumpkin but it might be good to pray for it before shifting
Don't worry...the MAF portion is much less tiring.
