This is for Bosch MG1 pre 6/2020 manufactured date and B58tu Platforms (M340i, GR Supra)

How it works

This service requires us to plug directly into the ECU/DME for the unlock or downgrade.

If you are not local you will need to ship us the ECU/DME.

EcuTek:

- If you have EcuTek and need the Cal Downgraded for specific reasons (Racerom issues, Port injection issues, Cam roll issues) -

The latest dealer flash gets patched to enable OBD programming.

A EcuTek Programming License is put on the ECU/DME at the time of the UNLOCK.

We can NOT easily use a license that was sold to you by another tuner. Please keep that in mind.

(We can offer discounts for other tuners/shops that require this service for downgrading the DME to firmware ID that racerom functions on, Some newer Cal ID Can mailboxes are reserved from factory and causes Racerom and port injection to not function at all.)

BM3 & MHD

ECU/DME gets downgraded to enable OBD programming.

You will need to contact BM3 support to reset your account so their software will recognize the changed ECU Version.
