What pids do what question + a couple more.

Hello All, Need a sanity check.
This is for a 2002 12212156 5.3 silverado.

I thought I'd group all of this together. I am about ready to start getting specific about using the logging and have a few questions. I think if anyone will help me with this, I will be able to apply other combination's on my own.

I think I understand that MAF and DYNAIR are used to find differences in SD/MAF air calculations. What is CYLAIR and DYNCYLAIR? Is it just the per cylinder of the total air? What is it used for?



I plan on using SSpdDmons balance IFR then VE and leave MAF cal @ factory(if possible). This only applies to balancing the IFR, I will ask about AutoVE if needed later.

My steps are as follows:
Lower B0120 to 400rpm. (make pcm use MAF only)
Copy and paste Hi OT spark to Lo OT spark. (get rid of spark scaling)
Set B4205 to a very high temp (make PCM OL only)
Set b0201 to 0. (shut off air pump)(thanks joecar)
Set b1301 to 0. (shut off EGR) (fom joecar)
Set c6002 MIL,DTC enable to off for b0201 and b1301.


Could you confirm my pid selection is correct?
TP
MAF
BEN1
AFR
ECT
RPM
WO2AFR1
SPRKADV
IAT
MAP (set to PSI)
KR
VSS

NOW! for the big question. Since IFR is ONLY vacuum referenced(2D) and it has no RPM dimension(3rd), how do I calculate/apply the changes? I understand using the reciprocal of the BEN. I just don't know how to apply it. I assume that a map is required.

I found this and cannot figure out how to apply it:

ANY help with this will be greatly appreciated,
