Description
Traditional ECU tuning is currently not possible on the latest Bosch units, as security has been significantly enhanced since mid-2020. All G-Series M2, M3, and M4 models use these updated ECUs. However, we offer a full unlock service that enables custom tuning, data logging, fault-code reading, and additional functionality. You can also revert the ECU to its stock settings at any time if you wish to install BMW remote updates.
Power output is instantly adjustable via the BMW drive modes, allowing you to tailor performance to current conditions.
