GM Global A ECU Unlocking Service

We are excited for our public release of our GM Global A engine computer unlocking services (also known as ECU, PCM and ECM).

This service will allow you to harness the capabilities of your vehicle. After the unlocking has been completed, you will be able to use commercial tuning software to modify your tune and unleash your vehicles true potential.

Fast. Easy. Affordable.

We pride ourselves on being able to offer not only a fast service, but the best pricing possible for any of our unlocking services.

If you can find competitor with a better price, let us know and we will beat it! (*Must be a business).

For all the workshops out there looking for an alternative, we got you. If you are already on a volume/distributor discount with another unlocking provider, let us know and we will beat it. 

Once we receive your ECU in the United States, unlocks are typically performed within 1-2business days and shipped back out immediately!

New and Secondhand ECUs

If you don’t want any down time, then you can purchase a new or used second hand ECU direct from us. These units are factory reset and include the unlocking service so they are ready to be fitted and security linked to our vehicle.

As a world first, we are also offering the ability to send in second hand ECUs to be factory reset and unlocked! This allows workshops to stock up with unlocked ECUs to provide same day turn around for their customers.

Our current range of workshops run an exchange system whereby they keep the factory ECU from the customer to ship in for unlocking services.

Once you receive the unlocked ECU, it will need to be security linked to your vehicle using GM’s Techline session with a suitable J2534 scantool. We are investigating into offering our own system to complete this task also.

What is Next?

In the near future, we will be offering our own tuning suite to allow tuning and making modifications to our supported ECU unlocking range. Until then, keep an eye out for new articles for sneak previews!
