Bosch highlights advances in motorsport ECU development

LinkedIn +

Bosch has been a pioneer of ECU technology in motorsport over the past four decades, with its control units equipping winning cars in almost every global race series. In this video, Bosch Motorsport race engineer Michael Stams provides an insight into the make-up of one of the company’s current ECUs and highlights how the units have evolved in recent years and how greater functionality has been compressed into a smaller packaging envelope.

In the case of the company’s current MS7.4 ECU, Stams notes that significant progress has been made on thermal management, with the unit required to operate a direct-injection, turbocharged I4 under full load without any external cooling provision. An impressive feat given that unlike past ECUs, the latest generation incorporates both injection and ignition drivers, which were previously located in separate housings.
