Delphi 85mm Maf Tables
Frost or Ryne can either of you post a screenshot of exactly what map to make? I made one but just trying to make sure Im doing it right. And am I understanding it right that you do the MAF after you reenable it??
Personally, I log commanded AFR and actual AFR to derive AFR % error and log that % error in a table that matches the MAF's so that the % error can be applied (copy and paste-special) directly back against the MAF in the editor.

If you're steady throttle and over 4000RPM (which you should be
with the converter) then it's all MAF for airflow. Verify this by the
Dynamic Airflow and MAF Airflow readings being identical. Use the
wideband WOT reading against commanded AFR to judge the MAF
(and injectors, and fuel pressure, etc.) accuracy.
Curved intake tract can bother the MAF, yours isn't but trucks
tend to be. Still I found the truck table put me dead right, back
before I did the cam swap. Then it went a bit to the rich side.
Have not revisited it since the intake swap.

this is for efilive.
also change {B0120} from 4000 to 400
this way you will be using the MAF only for calculated airflow.
this is not the best forum for tuning info IMO
hang out in the efilive/hptuners forums for better tuning advice.
and don`t worry about your VE not being 100%
there are too many variables from day to day for it
to be perfect each time you log.
