It was late last night when I typed that... <- me slapping upside my head 4x
Sorry, I had meant to type this: 0.85*IAT+0.15*ECT
i.e. it should biased toward IAT.
I intended that as a simple estimation, exactly what Shawn guessed I was doing...
I say this from looking at B4901 and from observing DYNAIRTMP_DMA say when VSS > 30 mph in various logs...
I should have instead said to study B4901 for your airflow range, which brings us to the next point:
A more accurate way to do this is to do a lookup of the B4901 values as suggested by mr.prick earlier in this thread...
and this is exactly what Ninety8C5 did: showpost.php?p=118165&postcount=29
[ but this still doesn't factor in B4902 ]

I see you have already found this: showthread.php?t=13320
Hmmm... I though I had seen an update for 19980200......I don't know now what I had been looking at (sorry).
Do what mr.prick said, Validate Pids.
Ok, I'm confused... I pm'd Tech Support regarding the 19980x00 os's support of these pids:
GM.CYLAIR_DMA
GM.DYNCYLAIR_DMA
GM.DYNAIRTMP_DMA
If DYNAIRTMP_DMA isn't supported, then the lookup of B4901 would be the way to go.

Ok, I'm told that those do not exist for the 1998 OS's... sorry.
So the next best thing is to use the lookup(B4901) method, see Ninety8C5's link in my post above (post #162).
Here is the current calc_pids.txt file for the tutorial (works for VE[%] and VE[g*K/kPa]).
The pdf is included in the latest install of V7.5.
cheers Joe! I saw that thread the other day but didnt think it applicable due to e38 but if it does the MAF its worth a shot
PS do you not know where anythings located
