Code 32:
EGR open command did not change MAP sensor signal. Normal EGR flow should cause slight decrease in manifold vacuum which would change MAP sensor signal.
Code 33:
MAP sensor signal voltage was too high (low vacuum) for 5 seconds when throttle opening was under 4%.
Code 34:
MAP sensor signal voltage was too low (high vacuum) when engine speed was under 1200 RPM or the engine speed was over 1200 RPM with a throttle position angle above 21%.
Code 42:
The EST signal did not change when the ECM applied bypass voltage to the ignition module.
Code 44:
Oxygen sensor voltage was under 0.2 volts for 50 seconds of closed loop operation. (Lean Exhaust Indicated)
Code 45:
Oxygen sensor voltage was over 0.7 volts for 30 seconds of closed loop operation with a throttle angle between 2% and 20%.(Rich Exhaust Indicated)
I've never experienced a sequence of error codes like this, so I'm only guessing at what the problem / problems are.
Trying the following steps will help remove some / all of the guessing at what wrong.
Maybe the swap loom is for a different engine or computer? Did the swap loom come with a wiring schematic? I know you have been over everything, yet this sequence of errors is SCREAMING wiring problems!! If you don't have the wiring schematics verify pin for pin; what are the voltages going to the MAP sensor, possibly no 5 volt reference? What happens to the signal volts going to computer when a hand vacuum pump is used to "Fake" a vacuum source to the MAP sensor when the ignition key is in the "ON" position / Engine OFF / NOT RUNNING? What is the "Bypass Voltage" when you try to start the engine with the High Volts Wire (the wire that goes from the coil to the distributor) is connected to the coil and the other end of the High Volts Wire is connected to a GROUNDED spark plug instead of being plugged into the distributor cap?
