Racetronics: C5554 Universal ECU
The C5554 powertrain management system is a universal modular design based upon the X5554 micro-engine. We’ve included the standard signal conditioning and device drivers common to gasoline and diesel systems while separating out the specific high-power drivers required for unique actuators. We have designed a universal driver interface for controlling external devices by combining high-speed digital I/O with a CAN bus for configuration and diagnostics. Customers can build upon the X5554 core and add specific external drivers to target peak-and-hold injectors, dumb ignition coils or the new piezoelectric actuators.
Built upon the real-time control framework (RTCF), our base powertrain management software and calibration dataset allows users to start running their engines out-of-the-box and begin dynamometer mapping procedures immediately.
The C5554 design utilizes a rugged water-resistant enclosure and features 4 MIL-spec standard motorsport connectors.
