www.bosch-motorsport.com

The engine control unit MS 3 F3X is a direct replacement for former FIA Formula 3 cars. The F3X software
gives the user full access which allows the mapping tobe adapted to any hardware changes. Traction Control
and Launch Control have also been enabled and arefreely configurable. Furthermore the ECU can easily beconnected to a C50 data logger or a DDU 7 display/logger.
