Common Questions

Why does my car need ECU unlocking?+

Many newer BMW and Mercedes platforms from 2020 and newer ship with locked control units. We unlock the ECU first so it can accept a custom tune. Without this step the calibration cannot be written.

How long does it take?+

The expected turnaround is under two weeks. We remove the ECU, unlock it on the bench, then reinstall and run a full scan to confirm everything communicates properly.

Which cars is this for?+

It is for newer BMW and Mercedes platforms with locked control units. When you come in for a look we will confirm your exact platform.

Do I need to pre book?+

Yes, ECU unlocking is a pre booking only service. The team will sort the details once you come in for a quick look at the car.
