How This Service Works

    Purchase: You are buying a high-quality, remanufactured OEM module from our inventory.

    Ship Your Original: After purchase, mail us your original faulty module. It must still communicate with a scan tool so we can extract your vehicle’s unique VIN, immobilizer data, and engine adaptations.

    Data Transfer: Our technicians clone your specific vehicle data onto our remanufactured unit using advanced engineering tools.

    Install & Drive: We ship our programmed module back to you. Simply install it and drive—no additional dealership programming or coding is required.

Functions Controlled by the ECM

The Hyundai Engine Control Module acts as the primary "brain" of your vehicle, managing:

    Fuel & Ignition Timing: Optimizes combustion for maximum efficiency and power.

    Emissions Systems: Monitors exhaust sensors to ensure environmental compliance.

    Transmission Communication: Coordinates with the TCM for smooth gear shifts.

    Security Authentication: Communicates with the immobilizer to allow the engine to start.

Warranty & Quality Guarantee

    Upgraded Internals: Our modules are remanufactured with high-quality internal components designed to address common factory failure points.

    Full Warranty: This package includes a comprehensive warranty covering both the remanufactured hardware and our programming labor.

    Direct Exchange: We ship your original faulty module back to you along with the newly programmed remanufactured unit.

How It Works

Ship us your faulty module. We extract your original data (VIN, mileage, key codes, calibrations) and transfer it to a remanufactured unit. Your old module is recycled for parts. You receive a plug-and-play replacement ready to install.
