MAGIC FLX2.79 – BootROM Cable for CM2250

This is the MAGIC FLX2.79 BootROM Cable for the Cummins CM2250 ECU (engine control unit). It’s a specialized cable used with the Magicmotorsport Flex programming tool to interface directly with the CM2250 ECU in Bench/BootROM mode for deep-level access

• Bench/BootROM Connection: Allows a direct connection between the CM2250 ECU and the Flex programmer bypassing the ECU’s normal firmware — useful when the firmware is corrupted, locked, or otherwise inaccessible.

• ECU Recovery: Enables safe and quick recovery of a damaged or “bricked” ECU by entering BootROM mode.

• Read/Write Firmware: Supports complete reading and writing of firmware data at a low level (even when the normal communication fails).

• Stable Bench Programming: Designed for stable ECU bench work, ideal for workshops and professional tuners.
