I have a 2012 isx cm2250 motor with a cm 2350 ECM my question is what needs to be changed so that it communicate together esn 79597170 cpl 3719 and the ECM cpl is 3937 and it’s a 2014

Thanks for your help and guidance
Diver

what truck is this on?... and what was the original engine ?... and what was the ser# of the original engine???

and I assume the the new enigne ser# is 79597170?

It’s in a Kenworth t680 2015. The original engine was a paccar don’t have a clue on that ser# as the Cummins was in it when I purchased it. And I believe that the ECM came from a different engine as well sorry I’m not much help here.and yes the 79597170 is what’s in the truck now

wow, that sounds like a complete clustered-Mess!

.. that enigne ser# comes back as a CM2250 engine.

-- I can also assume that the truck / engine is "Deleted"?.. other wise, THE ENTIRE EMISSIONS SYSTEMS THAT BELONGED TO THE CM2250 ENGINE NEEDS TO ALSO BE INSTALLED TO MATCH THE ENGINE TO MAKE IT LEGAL!... AND THEN REGISTERED AS A "GLIDER", AS IT IS A 2015 TRUCK with a non-compliant (2010 emissions standards) engine in it!.. .. so this tells me clearly that it is already a "deleted" truck and engine.

NEXT:;;.... A CM2250 ECM NEEDS TO BE PUT BACK ON THAT ENGINE!!!.. PERIOD!. The program needed should match the engine ser# as well. (program CL10138 in your case). This is the proper thing to do and what needs to be done to run it correctly.

-== And since it most likely needs "deleted" after, then that is easily cured by simply copying out and e-mailing the factory clean program so that it can be "de-mandated" properly instead of having some rip-off delete tuning idiot making things worse for several thousands of $$$.

WHO MADE THIS MESS BY THE WAY?/... I sure hope like h#ell that it was not a "certified" oem repair shop.. because what they did WAS ESSENTIALLY ILLEGAL (unless they put all the 2010 emissions systems on it too and registered it as a glider). it was not the best idea to use an outdated emissions engine in a 2015 truck to begin with... THEN to make it worse yet ... TO USE THE WRONG ECM!!>??q!.. What a mess!

[Mr Hagg]

Most of the time the multi plex will be off as far as where its getting its info. Make sure you have all that correct

okay to answer your questions as best I can.....No the truck is not deleted it has a full def/dpf system on and runs what I can say as it should. what or where it came from is beyond my knowledge. and as far as the ECM I'm not even sure where they got it from. now I do not have insite but I have access to someone that does. so if there is files or more information that is needed for this to be right then I will have to get with him and have him download the files for you to look at if you need that to see what is in there. and to who did this...…Truck Nation in Houston Tx. is the company that buys and sells lots of trucks.... I don't know if there are an oem shop. Now how do i check to see if its been registered as a glider?

It wasn't.........

your gonna be pulling your hair out for a year if you decide to play around with this abortion of a mess. Sell it, scrap it, give it away and buy something else.

Hi guys,
Got a truck with 2350 engine instead of 2250. Ecm, wires, intake manifold from 2250. I'ts 'tuned' and after checking seems to be a bad one with a lot of blocked faults and working not in chi4 mode. Injector codes seems not to be changed. Stock cal have to be cl10132, right now have cl10138. I will email uploaded cal file to Rawze and hope maybe he will have time to take a look.

A truck that was made for a CM2250 engine, and someone installing a CM2350 into it ...

I should at least mention that it is officially against EPA regulations (without also swapping all the 2350 emissions hardware to go with the newer model engine) .. otherwise, here is the info...

- An ISX cm2250 to 2350 swap, otherwise, consists of simply re-using the CM2250 wiring and ECM on the newer block. I think there is a fuel rail pressure sensor that does not plug in, and for this sensor, the older sensor needs to be installed instead. Other than that, everything else typically plugs right in. The CM2350 turbo that was meant for that ser# engine should also be used,.. and not the older CM2250 turbo.

- There is however NO factory program (or otherwise) from the red engine maker that will run the CM2350 engine hardware properly. A CM2250 program in the ecm will make it fire up and run.. but it will not be anywhere near correct for it, and it will result in efficiency losses, and eventual progressive engine damage (severely shortened engine life).

Everything from compression ratio, fuel-air-mix, boost levels, injection timing, injector spray angles, injector trim code logic, injector coil conversion logic, fuel quantities, cold ambient, cold weather settings, etc.etc. etc. ... are all completely different for a CM2350 engine. The ecm is also not going to compensate for any of this stuff at all. The ecm is beyond dumb as a brick and has no Super-duper AI fix-it sauce inside it. it will just tear the engine up slowly over time and not care at all.

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 things mentioned above need to be set, .. and if the emissions are kept, the emissions settings for the post2 injection cycle and a few other things needs tweaking a bit. -- I typically end up having to make several of these programs for people each year. Even the red engine maker and OEM network of morons and nitwits have been known to abandon people after they themselves do swaps like this, then finding out the hard way that there is no real solutions without custom programming.

give me a ring to talk about it and so we can get on the same page with what has been done. I PM'd you my number.
