Comprehensive Data Programming for Hyundai Elantra Dashboards

For a specialist company, having full control over the memory is critical. Unlike basic tools that only offer partial access, FORZA 614 allows you to perform a complete programming process for the Hyundai Elantra:

  • Full EEPROM Access: Read and write the entire 24C16 memory
  • Odometer Mileage Adjustment: Professional mileage programming capabilities to match the odometer reading after a cluster repair or replacement
  • Data Recovery: Fix corrupted data issues or "dead" clusters by restoring a verified hex dump from other cluster.

Flexible Workflow:
OBD2 in the Vehicle or Bench Programming

Time is money in a busy repair shop. FORZA 614 is designed to adapt to your current needs, offering two primary methods of connection:

  1. OBD2 in the Vehicle: Perform odometer correction and diagnostics directly through the diagnostic port for maximum speed.
  2. On the Bench via Dash Connector: The superior choice for remotely post-in services. You only need to connect 5 pins to the dash plug connector.
  3. Pinout in the App: All accurate connection diagrams and high-quality cluster photos are available directly inside the FORZA 614 software.
