The Details

This one-time service upgrades an original RAM CM2450B ECM and is required for tuning using HP Tuners’ software.

Users must physically remove their original ECM from their vehicle and ship it to HP Tuners’ headquarters for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.

Note: No IMMO relearn, crank relearn, or “Replace ECM” function in VCM Scanner is required as long as the ECM returns to the same vehicle it came from.
