The latest update for OBDSTAR X300 Classic G3, DC706, and ECU Master adds bench mode support for locked BMW B48, B57, and B58 engine control units. Below are answers to common technical queries regarding this protocol.
OBDSTAR Update Locked Bosch MG1/MD1 ECU Read Write Unlock (Coming Soon)
Q1: Can MG1CS201 and MG1CS024 DMEs (B58/S58) be flashed with OTS tunes over OBD after unlocking?
A: OBD flashing is not supported. The current software version only enables lossless bench mode operations for unlocking, reading, and writing data.
Q2: Will OBDSTAR release a dedicated solder-free unlock adapter?
A: No. Lossless pinout-based unlocking is currently exclusive to BMW ECUs. Other brands and models still require opening the ECU cover and desoldering resistors. As a result, a universal solder-free adapter cannot be produced.
Q3: Is reading, writing, or unlocking supported for Indian-market MD1 TC375 ECUs?
A: Not at this time. Chip unlocking is currently limited to the MD1 and MG1 series equipped with TC298 and TC2989 processors.
Q4: Can post-June 2020 Bosch MD1 ECUs be unlocked for read/write access?
A: Yes. Most encrypted MD1 ECUs produced after June 2020 using TC29X series processors are supported (including MD1CS012 and MD1CS003). However, MD1CS016 units using the TC399 processor are not supported.
Q5: Does this unlock allow writing to sectors 1-3 or tuning via OBD tools like Bootmod3 (BM3) or MHD?
A: No. Writing to sectors 1, 2, and 3 is not supported. While the update provides a permanent unlock, reading and writing operations must be performed using OBDSTAR hardware.
