Use your FLEX to easily reprogram, Update, or Modify the software of most engine control units directly through the vehicle’s OBD socket. A simple Internet connection gives you access to all the potential that the tool offers you. For more advanced or repair work, use the FLEXBox module to program the control unit in BDM, Bootloader, JTAG, and AUD modes. The device detects any connection or communication errors thanks to its cutting-edge design.
