Cm2250 swap to cm2350

[Rawze]

not sure about the smaller engines but an ISX cm2250 to 2350 is a matter of simply bolting up the ecm and wiring harness off the cm2250 onto the new 2350 block and connecting it all up, keeping to the older ecm. After that, a custom program must be made to make sure it runs correctly... emissions or not, because there is no 2250 ecm program from cummins that will properly run a 2350 block and injectors... but is it not that hard to make one if you know what your looking for.

basically, use the cm2250 ecm... the 2250 wiring harnesses, the 2250 emissions and all stuff will still be wired correctly.

On the programming side of things, the fuelling controller needs editing for the different injectors, injection timing, the calculator for the injector trim codes needs to be edited to read 2350 injectors, the cold ambient and cold weather settings needs adjusting,.. and if the emissions are kept, the emissions settings for the post2 injection cycle and a few other things needs tweaking a bit. -- i have had to do several of them this year alone, as the red engine maker OEM network of morons and nitwits seem to be abandoning ppl that have this type of engine swap done with no real solutions.
