RaceChip RS Tuning Box - M3 (F80) / 2014-

Plug-in performance for BMW M3 F80 2014 onwards

Unlock sharper acceleration and stronger midrange pull with this RS plug-in power module for the BMW M3 F80. This is the non app-controlled version for drivers who prefer a simple, set-and-drive solution. Engine-specific software works with the S55 twin turbo petrol engine to deliver a noticeable uplift in power and torque while keeping factory safeguards intact. It is a brilliant remap alternative if you want a quick, reversible upgrade without flashing the ECU.

How it delivers results

The module sits between the engine sensors and the factory control unit, using advanced optimisation software to refine boost and fueling parameters within safe limits. You get a smoother, harder pull through the rev range, improved throttle response and confident overtakes, all while retaining the car’s original character and protections.

Set-up made easy
