Test and rebuild:

We test every ECU on our purpose build HIL (Hardware In-the Loop) test rig before rebuilding your unit so that you can be sure of your diagnosis. Once the ECU has been identified as faulty, we move onto the rebuild stage. We use higher rated components than factory standard to ensure the ECU performs as good as, if not better, than a brand-new unit from the manufacturer.

 

Programming:

This ECU is coded to the vehicle, to save expensive main dealerships programming costs we ensure that all the coding information is retained, making this ECU plug and play when you receive it back from us.

We have provided rebuild service for main dealerships and specialist across the globe for many years. Our high Lifetime Warranty standards ensure that we provide the best service for all who utilise us. Our work defect rate is lower than 0.6% across all of our rebuilds which is why you can be confident in sending your ECU for rebuild.
