<DIV><FONT face=Arial size=2>My current short-term goal is to simply install a
throttle body/'747 system from a 4.3l GM truck or van. In the beginning I just
want it to work well enough to drive around daily. Question: Do you suppose
re-programming of the ecm will be neccesary?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Probably.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I assume the system would run without any
mods due to the similarities of the engine displacement, but I don't have any
idea of how well it might run.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Run, yes. Again GM never did Lan Cruisers,
and even engine to engine they vary, never mind from different brands,
combustion chamber design plays a huge role.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>My long term goal is to turbocharge the motor
with moderate boost (maybe up to 10 psi), fabricating an exhaust manifold
using the weld-el/sch40 method. I assume I will probably need to replace the
MAP sensor with a 2 bar unit, but I've not heard of anyone re-programming the
'747 for turbo use. Is this feasible for a non EE like myself (I have
programmed in C and other lanugages though and have a grasp of basic
electrical concepts)? I would rather not fabricate a new intake manifold for
port injection, that's why I picked the '747.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I haven't seen a 2bar 747, and I think it would
be neat.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't see where your going to get out of this
without reprogramming.</FONT></DIV>
<DIV><FONT face=Arial size=2>If I were you I wire it for a 747 and 749, and
then work out both.</FONT></DIV>
<DIV><FONT face=Arial size=2>Then when you want to T/C it you're half way
there with the 749.</FONT></DIV>
<DIV><FONT face=Arial size=2>Tune the 747 first, and then the 749</FONT></DIV>
