Hello everyone. I would like to know if anyone here has done this swap and can help me with some tips, or guide me what I can do please. I have this 2020 RAM 3500 HO Cummins 6.7 that I bought a while ago and installed a 2024 HO engine since the original engine was completely destroyed by the accident. So the ECM is the original of 2020 with the updated programming for cp 3.3, the transmission is the Original Aisin with the original wiring harness of the transmission by the vin that I bought in the Dealer. but the engine wiring is of the 2024 engine since the 2020 was destroyed as well. It starts perfectly but has Rough Idle after this exchange and I am trying to see what it can be. I had the 2024 Injectors, I changed them to the 2020s and they do exactly the same, I checked Lift Pump, Fuel Pump, New Filters, rail pressure, FCA, FRP sensor I changed it to another bought in the dealer thinking that it was that since sometimes it disconnected and controlled a little, but nothing. Everything is the same. I thought it was programming, a technician friend of mine from the Dealer reinstalled the Original calibration with the update to cp 3.3 and continuous the same. Any help I thank you or someone I can pay you to tell me how to solve this problem, anyway. Thank you. I have a video that I would like to upload here if possible.
