The key point on this truck is that the calibration inside the module has to match the fuel pump on the engine, and on 2019-2020 trucks that pump changed under the Y78 recall.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"sds-copy-guide\"\u003e\n\u003ch2\u003eThe ECM on the 2019-2024 Ram 6.7L Cummins\u003c\/h2\u003e\n\u003cp\u003e2019-2020 trucks were built with a Bosch CP4.2 high-pressure pump. All of them were recalled under Y78 (NHTSA 21V-880) to have the CP4.2 replaced with a CP3 and the PCM reflashed, and 2021-2024 trucks came from the factory with the CP3. After the recall, a 2019-2020 truck runs a CP3 calibration, and any calibration product, including what goes into a replacement module, must match the installed pump. Output and transmission matter too. Standard-output trucks use the 68RFE, high-output 3500s use the Aisin AS69RC, and the two have different TCM strategies.\u003c\/p\u003e\n\u003ch2\u003eWhat we carry\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eA brand-new Mopar CM2450 Cummins ECM, listed for 2019-2021 trucks.\u003c\/li\u003e\n\u003cli\u003eEFI Live AutoCal V3, blank, a standalone device for loading calibration files and logging data.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/duramaxtuner\"\u003eCalibrated Power\u003c\/a\u003e no-drill DSP switch bracket, listed for 2006-2022 5.9L and 6.7L Cummins.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFind more in our \u003ca href=\"\/collections\/tuners\"\u003etuners\u003c\/a\u003e collection or on the \u003ca href=\"\/collections\/cummins\"\u003eCummins\u003c\/a\u003e hub.\u003c\/p\u003e\n\u003ch2\u003eFitment notes\u003c\/h2\u003e\n\u003cp\u003eThe ECM listing stops at 2021, so check with us before ordering for a 2022-2024 truck.
