DFOX is an ECU and TCU programming system identified by DFB Technology SRL as its own design. DFB’s published driver list covers supported vehicle and control-unit combinations and identifies available operations and connection methods.
Connection methods and coverage
The manufacturer’s July 2025 driver list includes OBD, bench and open-mode applications, including boot and JTAG on certain control units. Depending on the entry it records read, write, virtual read and cloning support. These capabilities are application-specific: use the latest list and the protocol instructions to confirm the exact ECU, hardware, software version and required accessories.
Configurations
DFOX is offered in Master and Slave configurations, according to distributors. Confirm the enabled packages, file workflow, subscription and support directly with DFB Technology or its authorised distributor before purchase.
Relationship to FG Technology EOBD2
DFOX is sold as a genuine DFB Technology product, while FG Technology EOBD2 is a separately marketed FG Technology product. Their interfaces are almost identical in appearance, leaving questions about any underlying relationship. A third-party account alleges that DFOX originated with a former FGTech development group and shares its platform or hardware. That history has not been independently verified here. Similar appearance is not evidence that DFOX is a counterfeit or unauthorised copy of EOBD2, nor proof of a current corporate or licensing relationship. DFB’s own list identifies DFOX as designed by DFB Technology. Verify any individual unit’s identity and support entitlement with its claimed manufacturer.
Copies and identification
A DFOX distributor reports that DFB has identified KT200 and FOXFlash devices as copies of its product. This is an attributed manufacturer/distributor claim; it should not be used to classify an individual device without verification. Ask DFB to check the serial number, licence and supply history, and establish who will provide updates, recovery support and warranty.
