cm2350 ecm on cm2250 engine

[RGM]

It’s a buddy’s shop he also has a business of selling trucks and he happen to have this one that was sitting their. I was looking at and asked him what the story was on it and that’s what he told me they did an engine swap. All of the original emissions are still on it and hooked up. I was worried that it should’ve been programmed differently. I was just looking and thought that that swap wasn’t right from what I know. Thanks for the info.
