Doing a 454 carb to 454 TBI swap.

[87k5]

Hello to all,
I need some information on doing a motor swap. Here is my situation.

I have a 1988 CC that does not have the original motor with it. It is carbureted 454.

I have purchased a 1989 suburban with an original 454tbi installed. That motor has all the smog components installed. I have no interest in running a smog pump. If I decide it remove the smog pump, and associated components, will the ECM be able to control the engine correctly? I guess my question is: does the ECM have anything to do with the smog pump; are they in any way interlinked?

I’m sure I will have more questions to follow but I will start there. Your help is much appreciated.

Thanks,
Charles

ECM has nothing to do with the smog pump. Remove it and the ECM won't know the difference.

There is a setting in ECM for minimum temp for air pump, wire on pin C2... but no DTC, so no issue removing it.

What does DTC mean?
