DC2U-CR4 GPT cable

Description

The DC2U-CR4 GPT Cable is a specialized programming and diagnostic cable designed for advanced communication with CR4-type diesel ECUs via GPT (General Purpose Transceiver) lines. Ideal for use in ECU tuning, cloning, and firmware read/write operations, this cable enables secure and stable bench-top access to the ECU’s internal memory without opening the unit or applying risky soldering techniques.

Featuring a DC2U interface and dedicated GPT signal wires, the cable provides full support for boot mode programming, EEPROM/Flash data extraction, and firmware updates in a safe and controlled environment. It is widely used by automotive tuning professionals, remapping specialists, and ECU repair engineers working with modern diesel vehicles that utilize CR4 ECUs with locked or encrypted content.

Engineered for precision and reliability, the DC2U-CR4 GPT Cable is constructed with shielded, low-resistance copper wires to ensure clean signal integrity and protect against electromagnetic interference (EMI). Reinforced connectors and a flexible jacket provide durability in high-use bench setups. Whether you’re unlocking a secured ECU or performing in-depth software operations, this cable is an essential tool for safe and effective ECU-level work.
