iTronic RS BMW M4 CS 460hp S55 F82
Select the desired product
Upgrade your BMW M4 CS with our iTronic or ECU remap Stage 1 tuning. The iTronic is a highly advanced engine controller that works simultaneously with the original ECU and is highly recommended on new and young BMW models that still have the factory warranty. It is designed as an external module (tuning box) that can be installed and removed by the end-user, minimizing problems with factory warranty.
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. Installation and back to stock can be done by any official Mosselman Dealer, or at home with the iMoss DIY solution that we offer.
The Stage 1 tuning will take your BMW M4 CS to approximately 500 hp and 660 Nm on premium fuel (98 Oct EU/ 93 Oct USA), which is highly recommended. Additional to the iTronic or remap we recommend installing our MSL Oil Thermostat S55 to lower the oil temperature.
