Summary Notes

[joecar]

GM.DYNAIRTMP_DMA
Internal PCM calculated blended and filtered air charge temperature [C, F].

GM.CHRGTEMP_DMA
Internal PCM calculated blended air charge temperature before being filtered [C, F].

CALC.DAT
Scantool conversion of GM.DYNAIRTMP_DMA to various temperature units [C, F, K, R];
this pid is for convenience (its short name fits easier on charts/gauges and in calc pids).
Requires definition in calc_pids.txt file, see previous post for example.

If those are to be used in the Ideal Gas Law equation P.V = n.R.T = (m/M).R.T they must first be converted to [K].

Blending: see table B4901 Charge Temperature Blending.
Filtering: see table B4902 Charge Temperature Filter.
