Thanks for answering Dean2. The problem is that I bought this truck at the auction approximately 2 years ago and I never thought it had so much damage, the engine was very damaged and I even had to buy a new Chassis at the Dealer plus many other things, to the point that I just want fix it to keep it for myself and not sell it, which was what I thought at first, since I have invested too much money in it and right now it would not be a good deal for me. So I was able to get this 2022 engine at a good price since it was from another truck in the auction that was also destroyed but the entire rear end. As I saw when I looked for the new engine, it came with a 68RFE Transmission but mine is an Aisin and it is the one I would like to leave. Sorry if I don't give you the information you need. If you need to know any specific information, just tell me please. Thank you
I recall from RAM's literature that mechanical differences exist between the standard output and the HO engines. Standard output engines were only available in the 2500. I don't recall seeing a discussion about swamping in an SO to an HO controller. You may want to try looking at RAM Cummins engine-specific forums.
The H.O. Cummins that you originally had, and the S.O. Cummins that you want to install have physical differences and engine calibration differences.
Thank you very much Jimmy for this explanation. I wanted to ask you, I also have the Original 68RFE that comes with the new engine, but the problem is that the 4x4 is electronic through a switch, the 4x4 in my transmission is Manual. Would I have a better option if I put the Original 68RFE of the new Engine? Would I have any option for this, please?
Whatever you do the stock ECM/PCM is expecting sensor inputs and will deliver PCM outputs based on the original engine and transmission. The PCM must be compatible with the power train and associated wiring harness.
Like @Dean2 said, you could put the whole S.O. driveline into your truck- engine, trans, transfer case and drive shaft. Since the transfer case is electronic, you would need to add some wiring from the case to DTCM, and the electronic selector switch cluster, and a few settings changes with alfaobd. You would still need to use your original ECM (because it contains your truck’s SKIM info), but it’ll have to be flashed with a S.O. Cummins calibration.
Personally, I think it will be a lot easier to either replace the SKIM module, or use the keys, module and start button from the SO or re-set the SKIM info on the SO ECM, than to try and reflash the HO ECM for an SO motor and 6 speed. However, I haven't actually tried that so you may be right.
