Chiptuning, BMW Gxx B58
With an ECU remap, also known as “chip tuning” or “reflash”, the original ECU of the car will be recalibrated on several different engine parameters for more performance. Options like speed limiter removal and start/stop deactivation are available. Please note that an ECU remap will void the factory warranty once detected by a BMW dealer.
The ECU Remap will take your BMW M440i G20/G21 to approximately 420 hp and 600 Nm on premium fuel (98 Oct EU / 93 Oct USA), which is highly recommended.
