A:Yes, OBDSTAR ECU Master supports ECU programming and data reading/writing for many Mercedes-Benz models. In some cases, it can be used to adjust or remove the speed limiter, depending on the specific ECU type and vehicle configuration.
However, the availability of this function depends on the ECU version and whether full read/write access is supported. We recommend checking the exact vehicle model before operation.
For detailed compatibility, please contact us with your vehicle information, and we will confirm it for you.
