ECU Programming & Cloning — Bench Services in Ireland | VoltCheck Motors

ECU Programming, Cloning & Data Restoration

Modern ECUs control ignition timing, fuel delivery, boost regulation, emissions and communication across the entire vehicle.
When software becomes corrupted or internal memory begins to fail, the result can be no-start conditions, communication loss or incorrect coding.
This service provides safe bench programming, data repair and full ECU cloning using OEM-grade equipment.

What we do

Full 1:1 ECU Cloning

Precise transfer of all internal data from the original ECU to a compatible donor unit, including:

  • EEPROM

  • FLASH

  • immobiliser/security data (PIN / CS / ISN)

  • VIN and coding

  • calibration data

All cloning is performed on the bench for maximum safety and stability.

EEPROM & FLASH Repair

Restoration of corrupted memory caused by:

  • failed OBD tuning

  • incomplete writes

  • voltage instability

  • incorrect file modifications

  • internal checksum errors

Validated data sets and secure protocols are used to rebuild damaged software structures.

Virginising Donor ECUs

Preparation of used ECUs for installation into another vehicle:

  • clearing immobiliser lock

  • resetting VIN/configuration

  • restoring factory coding

  • enabling adaptation and relearn procedures

This allows donor units to be coded and paired properly.

VIN / PIN / CS / ISN Transfer

Secure extraction and transfer of immobiliser-related data:

  • VIN

  • PIN

  • Component Security (CS)

  • ISN

  • synchronisation data

This ensures correct communication between ECU, BCM/UCH and immobiliser systems.

Software Recovery (After Failed Flashing)

Recovery of ECUs that became unresponsive due to:

  • bad tuning files

  • wrong protocol usage

  • partial writes

  • tool failure

  • voltage drops

Bench/boot protocols allow full restoration of ECU firmware and memory layout.

No-Communication Diagnostics

Identification and repair of:

  • no communication over CAN/LIN

  • intermittent or unstable signals

  • internal hardware faults

  • corrupted memory sectors

  • failed power/ground circuits

Data Extraction (EEPROM/FLASH)

Safe bench extraction for:

  • immobiliser work

  • donor preparation

  • backups

  • fault investigation

No risky OBD reads — only secure bench/boot methods.

Bench Programming (No Vehicle Required)

ECUs can be programmed or cloned without the vehicle, ideal for postal customers and workshops sending modules for off-car repair.

Typical ECU Problems We Solve

  • No start / no crank

  • Crank but no fire

  • No communication with ECU

  • P0601 / P0606 / P061B internal faults

  • Incorrect VIN or coding

  • Software corruption

  • Immobiliser mismatch

  • Failed tuning attempts

  • CAN communication errors
