Streamlined Tuning for Modern Workshops
The EOBD2 Slave Tool (often associated with the FGTech Galletto lineage) is built on a “Network Model” of business. By using a Slave tool, you benefit from the safety of proven, dyno-tested files provided by your Master, while avoiding the massive investment in file-editing software (like WinOLS) and the technical liability of writing your own maps.
Key Technical Pillars & Semantic Entities:
-
All-In-One Communication: Unlike many tools that require separate hardware for OBD and Bench work, the EOBD2 interface handles OBDII, JTAG, BDM, and Tricore Boot modes using a single main unit.
-
Encrypted File Transfer: The tool automatically encrypts every file it reads from a vehicle. These files can only be decrypted and modified by your specific linked Master, ensuring a secure and exclusive business relationship.
-
Universal Voltage Support: Natively supports 12V and 24V power, making it a rugged choice for heavy-duty tractor and truck tuning where high-amperage stability is required.
-
Bench +ULTRA Extension: Supports the latest “Bench” protocols which allow you to read/write the ECU via the pinout without opening the casing, preserving the factory seal and reducing the risk of physical board damage.
-
Automatic Checksum: Includes built-in checksum correction for most protocols, ensuring the vehicle’s software remains valid and the engine starts immediately after flashing.
Technical Compatibility:
| Category | Supported Protocols / Systems |
| Connection Types | OBDII, BDM (Motorola MPC), JTAG (Renesas), Boot Mode (Infineon Tricore) |
| Vehicle Types | Cars, Motorcycles, Trucks, Agricultural Tractors, Marine Vessels |
| Voltage | 5V – 30V Auto-Switching |
| Software | EOBD2 Proprietary Suite (Available in 17+ languages) |
Business Advantage: The Slave tool is significantly more affordable than the Master version. If your business grows to the point where you wish to write your own files, FG Technology offers an upgrade path to convert your Slave hardware into a Master tool (subject to release by your current Master).
