MAIN FUNCTIONS

IMMO OFF

The software provides an IMMO OFF function for supported Kia/Hyundai ECU versions. Availability depends on the exact ECU software/hardware version.

CAT OFF

CAT OFF processing is available for supported SIM2K and applicable ECU variants.

FILE PROCESSING

The software is designed to process ECU files according to the selected ECU type. Select the appropriate ECU family, load the original file and process it using the available function.

HARDWARE MODIFICATION

Some supported ECU versions may require hardware modification before the modified file can operate correctly.

The integrated instructions section provides wiring and modification information for supported ECU types.

WIRE CUTTING / CONNECTION INSTRUCTIONS

For certain ECU versions, the software includes dedicated wire-cutting or wiring instructions showing the required ECU pin connections.

CHECKSUM

Some operations require checksum correction before the modified file is written back to the ECU. The software instructions indicate when checksum correction is required.

IMPORTANT

Always identify the exact ECU hardware and software version before processing a file.

Do not process an ECU file using an incorrect ECU selection.

Some ECU variants may require hardware modification, wire cutting or specific connection procedures.

Some hybrid/CAN-FD variants may not be supported.

Support depends on the exact ECU hardware, software version and file structure.

This software is intended for professional automotive ECU technicians and workshop use.
