AutoTuner adds direct Bench access for BMW DDE8 and DME8 ECUs

Protocol update: August 2026

AutoTuner has introduced direct Bench read and write support for selected Bosch DDE8 and DME8 engine control units used in BMW Group vehicles.

The update removes the previous requirement to send supported ECUs away for unlocking before Bench programming.

Supported ECU variants

• Bosch MD1CP032 – TC299
• Bosch MD1CS001 – TC298
• Bosch MG1CS024 – TC298
• Bosch MG1CS049 – TC298
• Bosch MG1CS201 – TC298

The release covers selected applications across BMW, Mini, Alpina, Toyota and Morgan.

What has changed?

Supported ECUs can now be accessed directly in Bench mode using AutoTuner, without the previous mail-in unlock procedure.

Following the required preparation, the ECU can also be patched to enable subsequent OBD flashing.

This does not mean that every BMW manufactured after 2020 is supported. The exact ECU variant and available programming method must be confirmed before work begins.

What this means for vehicle owners

For supported vehicles, ECU programming and bespoke calibration can now be carried out without sending the control unit away for the previous unlocking procedure.
