How does the iTronic work?
The iTronic is an highly advanced engine controller that works simultaneously with the original ECU. It connects with a couple of sensors from the car, including the mass airflow sensor and CAN connection. This allows us to read a lot of data of the car, for example RPM, temperatures and pedal position. Due to the CAN connection you can also turn the iTronic ON/OFF by the RES button on your steering wheel. With the optional exhaust valve function you can even open or close the exhaust valve whenever you want, regardless of the BMW performance setting.
