MAGIC FLX2.81 BootROM Cable for Cummins CM2350B – CM2450B

This cable is used primarily by professional tuners and technicians working on heavy‑duty Cummins engines (often found in trucks such as Dodge/RAM or commercial vehicles). It allows you to:

• Connect the ECU on a bench (without the vehicle connected) for programming.

• Enter BootROM mode to recover or restore an ECU when normal communication fails (e.g., corrupted firmware or a “bricked” controller).

• Perform low‑level read/write operations directly on the ECU hardware, bypassing the installed firmware.
