I got onto the Delphi web site today and dug up
a bunch of MAF info, pretty interesting (to me).

There appear to be only two "mainstream" MAFs
out there for LS-1 & related engines (as of 2001).
The site is a "little bit dated" in its applications info.
The trucks and Northstar / Aurora passenger cars
all use the same unit indicating a common MAF cal,
with any PCM table differences then relating to intake
tract details.

AF10043 is the 85mm truck MAF. This is very widely
used across all GM product lines, identical. The apps
do not go as far as 2002 where the Z06 went to a
descreened version; I was not able to find that one
and it may be an oddball. I would very much like to
find more info on that one. Interestingly this same
MAF is used on engines as big as the 8.1L. Hmm...
now -that-'s an engine swap....

AF10044 is their P/N for the 75mm F-body MAF.
It was also used on the Express and P30 vans 2001.
A fairly limited usage base but at least there are
other donors out there.

AF10045 is a very similar-appearing, but somehow
different, 75mm MAF that was on the LT-1 and V6s
very extensively. I was unable to find anything on
how the calibration differs, if at all. But the similarity
in appearance makes buying an unlabeled Oreo MAF
a bit dangerous, I think.

@jimmyblue, could you post a link to the site, please?

I am trying to find the MAF calibration table for a delphi product, and I am not seeing this info anywhere.

I am programming my own ECU for this build and would appreciate not having to go to the trouble of calibrating my MAF.
