Engine Control Unit MS 12
www.bosch-motorsport.com

The MS 12 is the high-end ECU for Diesel engines. ThisECU offers 12 Piezo injection power stages for use inup to a 12 cylinder engine. Various engine and chassis
parameters can be measured with a high number of input channels. All measured data can be transferred via
FireWire interface to an optional flash card data logger. Gear box control strategies are optional.
