MaxxECU map unlock for tuners and workshops
We unlock MaxxECU saves that MTune refuses to show because the previous tuner locked them. Drop the save in the MaxxECU tray and the read-out tells you what is inside first.

How MTune locks a map
A tuner can turn on MTune’s protection for a save, plain or encrypted, and MTune then keeps its tables out of view.
Only the save itself passes through the desk. The unit is never flashed, and every calibration value comes back unchanged.

MaxxECU questions
- Which MaxxECU files go in the MaxxECU tray?
- MTune files: .MaxxECU-save. Send the file as MTune saved it, not an export or a screenshot.
- Does the MaxxECU unit need to be on the bench?
- No. Only the file travels. The unit stays in the car until you are ready to connect.
- How long does a MaxxECU read-out take?
- The free read-out normally comes back within a few seconds of the upload finishing.
