BMW M4 F32 M-DCT 7sp 3.0T, S55B30T0 MY2014 – #Etuners Stage1 98RON
The S55B30T0 is quoted as having 317kw at the engine by BMW. Our pre tune dyno runs showed a very high 278kw at the wheels.
A custom Etuners file was calibrated via the OBD port giving us full access to all calibration areas in the ECU. This allows us to adjust additional maps such as throttle and torque which can’t be modified via a plugin module.
The final result being 321kw at the wheels, a gain of 43kw with power staying strong to redline. This is the advantage of custom tuning!
- Maximum power at the wheels: 312 wkw (measured stock at 278.7wkw), gains 34wkw
