On a CCC:
You'll need the right MAP,
TPS, Seems likely to be shareable.
  ESC, and KS probably different.   You'd have to call Chev or Parts House
for accurate info., I'm not sure.
For the intial fire it up to see of it runs, I'd disable all the malfunction
flags.
Set the timing, and immediately try a chip with like you said 13-44-45
disabled, and closed loop/learn temps set to FF.
Depending on what you actually doing, you'll need the fuel pump signals
wired in.

None CCC:
gonna need a TPS, in addition to the above..
