Our Services

At NZECU, we specialize in expert-level ECU and TCU services for modern vehicles. Whether you're facing a faulty unit or need programming support, we provide reliable, fast, and professional solutions using the latest automotive diagnostic tools.

ECU Cloning

We copy all essential data from your faulty ECU into a working unit — fast and risk-free.
Our ECU cloning service ensures all data from your original unit is safely transferred, including:

  • VIN number

  • Immobilizer data

  • Odometer reading

  • Software settings and remaps

Once cloned, the replacement ECU is Plug & Play, requiring no additional coding or dealer intervention.

Free initial assessment. No charge if cloning is unsuccessful.

TCU Cloning (Transmission Control Unit)

We duplicate your TCU’s complete transmission profile for smooth and accurate gear shifting.
We preserve:

  • Gear calibration and learning values

  • Transmission software and VIN pairing

  • Adaptive driving behavior

Ideal for replacing or upgrading transmission modules without needing to reprogram the car.

Free initial assessment. No charge if cloning is unsuccessful.

ECU & TCU Programming

We reprogram replacement units to match your vehicle’s configuration.
Services include:

  • VIN and immobilizer alignment

  • Key adaptation

  • Flashing original or updated software

  • Matching modules to your vehicle’s network

This is essential when installing new or used units that can't be cloned.

Bench Testing

We test your ECU/TCU outside the vehicle to identify faults before replacement.
Using professional tools, we verify:

  • Communication and data reading

  • Software integrity

  • Power and grounding faults

This service is perfect for confirming whether your ECU/TCU is actually the source of the problem.
