Important Information

The replacement ECU must be security linked to the vehicle before the car will be able to start. This security linking procedure is the process of programming the cars unique 4 digit immobilizer code (immo code) and key information into the engine computer so that it is allows to start the car. Without this security linking, the vehicle will not be allowed to start.


We can perform this security procedure for free if the vehicles original Body Control Module (BCM), Powertrain Interface Module (PIM) and ignition key is supplied to us. We do not need you to supply the cars immobilzer code as we can obtain this ourself and will security link the replacement ECU to your vehicle parts.


Alternatively we can supply a guide that explains how to perform the security linking which a local dealership or workshop can follow. The guide supplied demonstrates how to use a GM Tech2 but the same steps will apply to other suitable scantools. This options requires a workshop to know the 4 digit immobilizer code for your car to be able to security link it, this can be obtained by calling your local Holden Dealership and providing proof of ownership.


Finally, a throttle body relearn may be required after fitting and security linking the ECU to the vehicle. This can only be performed once fitted to the car.
