I have been looking into removing the Chrysler ECM that is on my 05 Dodge 5.9 diesel and replacing it with a 3 prong ECM like the 2nd Generation trucks have that the actual Cummins repair shops can talk to using the Inline software.

My question is....Has anyone ever tried this conversion? If so, please chime in. If you prefer to not make anything public, feel free to email me. I am very serious about finding out how this can be done and the steps involved. I have the funds to make this a reality, but need more information. Look forward to hearing the input!

Doubtful it will work. The 2nd gen ECM's do not contain enough memory and processing power to handle the CR controls. You would have to have a CR ECU that would take the Dodge specific programs by year. If you try to replace the ECU programs with something other than the Dodge software you will loose a lot of the functionality that is specific to the truck.

 

Yes, this makes sense. I was using the 2nd Gen as an example because the ECM is 3 prong that allows the Cummins repair centers to talk to the ECM unlike the Chrysler 2 prong. Hope I am making myself clear. Thanks for your input!

 

You wouldn't have to use a 2nd gen ecm. You should be able to use a regular CM850 ecm. I think the biggest difference between the ecm's is the non-chrysler ecm's use an additional 4pin power harness, in addition to using different software. Not sure if the pinouts would be the exact same - should be very close. Don't know what the big advantage would be of swapping ecm's, other than having a little more user interaction, tip info, etc. You would, however, have to have insite and the inline adaptor to communicate with it - and to program it as well. I'm sure it would be pretty tough to get anyone to program it knowing that it was going on a chrysler motor. I did see a fummins with a non-chrysler ecm - had a weird tps issue - don't know if they got it figured out. Not sure what you're after, but maybe an aftermarket ecm like the nira would be a better way to go?

 

I will check into what you mentioned above. I want to be able to have more interaction. I was told by a source I won't mention here if I can find an ecm like Cummins puts on their engines that don't go into the Dodges, they would be able to program it and turn the power up and other things. I will most likely have to get a whole new wiring harness for the truck etc. Thank you for your feedback!
