Data Logger C 70 Manual

Bosch Motorsport

17 Firmware

17.1 Firmware and configuration

C 70 holds 4 types of data:

Firmware: the software (PST program file) of the C 70.

Configuration: the configuration of Input channels, CAN I/O, PWM, display configuration,

rec telemetry configuration.

Calibration data: Characteristic curves and offsets created by online calibration at the

vehicle.

Recorded data: Measurement data recorded during vehicle operation.

17.2 Firmware update

The scheme shows the process during each connection between RaceCon and C 70.

17.2.1 Performing the firmware update

Firmware update is only possible if the C 70 is connected to RaceCon.
