Control Electronics

The Control Electronics, or ECU (Electronic Control Unit), is a high-tech unit that controls the electrical systems on all F1 cars, including the engine and gearbox.

With more than 300 sensors on today’s F1 car, the system needs a supercomputer to read, analyse and instruct the car, controlling everything from traction to engine modes and braking.

Teams can use two ECU’s in a season before incurring a grid place penalty.
