Cummins N14 engine swap question

We recently spun a bearing in our n14 celect plus 460hp motor. The crankshaft had micro fractures and was bent. We decided to grab a motor from rydemore in Fitchburg Ma. We bought a n14 celect ESP plus motor 375-435hp but the computer reads 460hp. Rydemore had the motor running and stated it had a skip in the motor which sounded like an injector. We replaced mains and rods in the bottom end and everything looks great. The rest of the motor has newer reconditioned cummins parts. My question is which ECM should I use. The one from the spun bearing motor or the one that came with the motor from rydemore?

I put the computer from the spun bearing motor on and we fired it up but black smoke is pouring out. Now I know there is an injector issue already but could it be worse because I didn't use the computer that came with the motor from rydemore?

 

Both motors are celect plus motors one is a celect plus ESP the ESP models are for climbing hills

 

Those are the engine data plates for each motor

 

Thanks guys. I guess in my mind since the two ECMs were reading 460hp I went with the one that was already matched to my truck but I was wrong and it dumped a whole bunch of fuel in the cylinder causing the black smoke. Ive cross referenced parts on the two motors and the injectors are different. Wire harness is the same so I don't have to worry there. I am going to switch computers out this morning and see if I can isolate the bad injector.

 

Yes it was. We went and looked at it first. You could tell the only thing that got ruined by water was the alternator. No water in the oil whatsoever and all reconditioned parts on it. We ripped the bottom end off and did mains and rods just because it was easy while it was out.
