Description
Our Stage 1 ECU upgrade for the turbocharged M2 N55 engine delivers a noticeable improvement in both power and torque through precise optimisation of the engine management software. The ECU is programmed directly via the vehicle’s OBD port, allowing efficient installation and greater focus on refining the calibration. This method also enables the vehicle to be returned to its factory settings at any time by reinstalling the original software.
Instead of using one-size-fits-all files, every tune is individually developed and extensively tested on the dyno to achieve the best balance of performance, smooth power delivery, and long-term reliability. Installation is performed via the vehicle’s OBD port for efficiency, and the original factory software can be reinstalled at any time if required.
Estimated performance after remap:
-
Power: 395–410 bhp
-
Torque: 425–445 lb-ft
