<DIV><FONT size=2> I'm sure I'll have many questions, some more stupid
than others, but I'll try to keep them to a minimum and in small
doses.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Just ask, dosages don't matter, but, the answers might get
overwhelming.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>First before I start hunting the boneyards and hacking
wires, is there any other ECM I should consider instead of the 747 and
why?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Nope, Tunercat has a demo for editing that one, so it's real
cost effective to get in on that.</FONT></DIV>

<DIV> </DIV>
<DIV><FONT size=2>The stock ECM seems to have more wire inputs used than the
747 based on the connector ID chart. Most of the connections are obvious, but
obviously some are unneeded(doubtful) or need to be combined. Any and all help
on this would be helpful. Doesn't GM make a " convert your Crossfire to 747"
diagram or harness adapter? :)</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>They all about line up just using colors, the only sneeky
thing was the SES (Service engine light) the 747 doesn't use the driver board
(green dealy).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Since the stock harness to ECM doesn't use a pin connection,
are there connectors that will mate to the stock harness? I'd rather make a
harness adapter rather than hack off the stock one if possible.</FONT></DIV>

<DIV><FONT size=2>(916) 685-1055 has the bits to make the adapter, talk to
John. Ain't pretty but has the parts to make it work..</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Exactly what does the calpac do and how does it relate to
the vehicle/engine/drivetrain combination?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The netres sets the limp home mode fuel.</FONT></DIV>
<DIV><FONT size=2>The prom contains the calibration for vehicle.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> Since I'm on a budget, when I find the ECM I would
like to get it ECM with the right calpac and a good starting prom would be
nice too. How close does the donor vehicle have to be to my project
vehicle as far as cubic inches/gearing/transmission etc.</FONT></DIV>
