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?
Probably.
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.
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.
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.
I haven't seen a 2bar 747, and I think it would
be neat.
I don't see where your going to get out of this
without reprogramming.
If I were you I wire it for a 747 and 749, and
then work out both.
Then when you want to T/C it you're half way
there with the 749.
Tune the 747 first, and then the 749
