Description
LAUNCH • X431 G3GIII PCadaptor X-PROG3
Designed for professional automotive technicians, the LAUNCH X431 G3GIII PC adapter X-PROG3 functions as a high-speed USB accessory for the X-PROG3 system, enabling efficient ECU and TCU cloning, reading, and writing via PC. Constructed to support BENCH and BOOT modes, it offers data validation, a clear 2D menu interface, and over three times the speed compared to Android-based tools. The global version removes IP restrictions—but note: one PC adapter binds to a single X-PROG3 unit only. Software updates are free for the first year; thereafter, renewal is required.
