Bruce,
	The 8051 supports 94-95 LT1's in all bodies but the
Corvette. The 1333 is used in the same year corvettes. They
actually seem to share the same code. These PCM's have two
Processors called an Event and a Time side. The time side
has a Flag that is actually part of the IAC calibration,
Thats interesting since you refer to the Air Flow Mode
word.  The flag I found is used in the Corvette Bins I have,
but not in F-Body bins.

My code starts at 0x2000, so Addressing is all different.
This flag is a byte, not a bit, But I do have 4 Bytes of Bit
Flags. There are a couple In the AFR section I haven't
figured out yet. I will check them accross some chips to see
if any corelate with Manual trans. Never associated Manual
trans with Air Flow til I got your note>
