<DIV><FONT size=2>MAF to MAP-- what parameters change on the chip--lets say
anything V8 in a 1227727 1987-1990 PCM.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT face="MS Sans Serif" size=2>Jus to be picky, it's ecm. Anyway
some chips have both the calculations in them, and they run all the time, just
a matter</FONT></DIV>
<DIV><FONT face="MS Sans Serif" size=2>of what input is used, "I
think". There are hundreds of chips that fall into this 87-90 727
arena, so I wouldn't begin to make a blanket statement about what has how
when. Using a MPSI scanner, I have seen a bin that would display
grams/sec, and K/Pa, at the same time.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> There were TSB's back in some of the earlier V6 apps,
like a 2.8 VIN "W" that went from MAF to speed density to correct
driveability...I'm just curious what was changed on the PROM and if they used
the existing wiring to adapt a MAP sensor. Never did any of these
yet...</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="MS Sans Serif" size=2>I've been told it was a chip, and
sensor change, but I also, never have done one.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>My other question was whether someone has done a diff
ratio/engine/trans (RPO stuff) vs. Memcals or PROM's cross
reference...wouldn't this be kinda interesting ?</FONT> </DIV>
<DIV> </DIV>
<DIV><FONT size=2>Your local GM dealer has a CD with all that on it. I
can do some of it ie Engine, emission, tranny, RPO stuff, but it's time
consuming.</FONT></DIV>
<DIV><FONT face="MS Sans Serif" size=2>That's why I was asking what you have a
guestion on.</FONT></DIV>

<DIV><FONT color=#000000 size=2>Hey, CSH--is the archive zip a complete
info pack from the past years, or is it </FONT></DIV>
<DIV><FONT color=#000000 size=2>just a digest version of the last year
?</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT face="MS Sans Serif" size=2>Goes back to day one.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2> I've just started going through
it--it's a 7+</FONT></DIV>
<DIV><FONT color=#000000 size=2>Meg file, so there's a lot of
reading...</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 face="MS Sans Serif" size=2>Funnier still is,
when in two weeks they start adding stuff that you missed the first
time. I've been thru them dozens of times start to finish, and every
time I grasp something new, it sheds light on something, else, and so
on+so on.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>still trying to find some concrete info on
MAF to MAP...</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 face="MS Sans Serif" size=2>What specificlly do
you mean?.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>found the VATS byte and transmission
byte (thanks ECMnut !!). Does anyone also have a RPO to Memcal cross
?? That'd be a real treat...</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>What is your question?. Give me a BCC and I'll try
to match it up.</FONT></DIV>
