Secondary ve table whats it for?

This is the table used when the MAF sensor fails. It serves the same purpose as the primary, but more as a backup table when in speed density mode.

when i am altering the primary should i do the same changes to the secondary... should i do this right away or can it wait until i finished tuning the primary?

If your SD tuning, changing the primary won't do anything because the PCM is running on the secondary table. If your sure the primary is correct, you can copy/paste just the kPa/RPM ranges needed to the secondary.

Secondary VE Percent vs. RPM vs. MAP: This table is used in some code variations when MAF failure is detected.

- from the help file, Anyone know what code variations?

Any time the car is in speed density mode.

Unplug or disable your mass air meter and the PCM will be using the secondary VE table.
