Confused about ignition tables.

[THUB]

Hey all, I'm tuning a boosted truck on a custom OS (02020003) with no MAF. I'm pretty confident about most of the tuning aspects and it's been going well, but I'm confused about the units used for load in the high and low octane ignition tables (B5913&B5914) It's using G/cyl, which I assume is based off the MAF reading because the PID in my logs just sits at 0. Is there a way to calculate those numbers into KPA? Is it actually referencing a different PID altogether that I'm not logging? Thanks for any help with this

Log either GM.DYNCYLAIR_DMA (as indicated on the g/cyl axis);if this pid is not available, then log GM.DYNCYLAIR (no _DMA on the end).

GM.DYNCYLAIR_DMA and GM.DYNCYLAIR are VE based.

The HO/LO tables are referenced by cylinder airmass which is different than airflow.
