What are the differences between the DYN air pids

under "Tune" and the ones under "Air"

The ones under "Tune" are extracted by EFILive directly from the PCM's memory. (All PIDs with the "_DMA" extension are "Direct Memory Access" PIDs)

The ones under "Air" are the values exported by the PCM as PID data for scan tools. The PCM generates the "Air" values from the raw data found in the "Tune" memory locations.

There should be no difference in their value. The "Air" values may lag the "Tune" values by a frame or two.

Cool good to know.
