Problem Description

After specific updates, it is impossible to flash these engine computers through the OBD port, and they need Bench Unlock for it.


We do offer Bench Unlock for MG1 engine computers, and after this unlock, you can flash it thru OBD.

How it works

You will need to send us the engine computer. We do Bench Unlock, without opening, thru regular connectors and send it back.

If you are local to San Diego, California, DME Bench Unlock can be done on the car without removing the DME.

As a majority of our services, it is the same-day turnaround.

You can find MG1 at this location:
