Note: This service from HP Tuners is specifically for 2022–2024 RAM medium and heavy-duty trucks equipped with the CM2450B ECM and the 6.7L Cummins engine. Use of this service requires the latest version of VCM Suite BETA.

Get your 6.7L Cummins ready for tuning with the HP Tuners RAM CM2450B ECM Service. This one-time, send-in service upgrades your original CM2450B ECM, enabling full custom diagnostics and tuning support in VCM Suite and bringing professional-grade control to modern diesel platforms. Once upgraded, you have full access to calibrate, log, and scan via the OBDII port using an MPVI3 or MPVI4 interface. There is no need for an IMMO Relearn, Crank Relearn, or to perform the “Replace ECM” function in VCM Scanner, provided the ECM returns to the original vehicle.

This is a send-in service, which means you must first send us your original ECM. Please read this page in its entirety before purchasing.

*ECMs must be the original unit from the vehicle. Spare ECMs will not be accepted.
