My completely uneducated opinion:
Any ECU on a gen 4 chev can be tuned to pass emissions providing the same sensors are used. The way I look at it, the ECU controls a number of things based on what information it received from the sensors on the engine. The tune within the ECU determines the outputs. To say a loom or ecu is not "emissions compliant" is not correct IMO (the tune may not be). As far as the engineer is concerned, the only important thing is that you have the piece of paper from the testing facility saying it passes. He shouldnt be worried about which wires go where or whether your ECU has 2 or 3 plugs.
