Cm570 help

But that was because the 870 needed to be rebuilt. But what I'm more curious about is what would stop me from swapping over sensors and wiring and putting my 570 ECM on? They are even comparable HP ratings. And I would swap over our manifolds, turbo, and any EGR delete I would need. The 570 runs, but major mechanical issues. Would the head be different? I can't necessarily see that. If it's just EGR and emissions, what needs to be changed?

well I guess if you know nothing about cummins engines ... then they are the same right?...


sounds to me like a lot of blind assumptions and guessing on a subject that someone somewhere obviously knows absolutely nothintg about.

a CM570 has a much lower compression ratio (depending on year/model) than anything newer and it also requires less internal friction control. - I.E.> Anything that was meant for emissions IS NOT GOING TO LAST AS LONG AS IT SHOULD IF YOU GO SLAPPING A CM570 ECM ONTO IT IS LIKE A BLIND FOOL!!!...

SO THE MORON WHO SHOVED AN 870 BLOCK INTO A VEHICLE AND RAN IT WITH A 570 ECM, DOOMED IT TO HAVE HALF-ITS LIFESPAN, CUT BY NOT RUNNING IT TO WITHIN ITS NEEDS AND PROPER SPECIFICATIONS!.


FIX THE DAMNED CM570 (cheapest and easiest to do) ... OR CONVERT THE WIRING AND EVERYTHING ELSE TO FIT A NEWER MODEL ENGINE ALONG WITH THE NEWER MODEL ECM TO RUN IT WITH PROPERLY!!!

- and if it is to be fitted with a newer model engine.. Then a cm871 would be the best choice, as it has a proper electronic vgt turbo.. And not an 870 with its more wonky, air-driven, problematic turbo design.
