A3 ECU

• CAN J1939 data link • Waterproof connectors • Maintenance-free • Backup ECU for redundant governing

Electronic Advantages:

• Load feedback • Programmable droop • Adjustable gain • Adjustable fuel/air ratio control • Histograms of engine operation • Cat Messenger display presents diagnostics and other engine parameters

Data Advantages through J1939 Link:

• Engine speed • Boost pressure • Throttle position • Fuel consumption rate • Inlet manifold temperature • Diagnostic codes and events • Configuration • Desired engine speed • Battery voltage • Engine load • Lifetime totals — engine hours, fuel burned, idle fuel, idle hours • Trip totals — average fuel rate, idle fuel, idle hours, engine hours, fuel burned, trip reset

Customer Interface Panel

• Interfaces with standard Cat® Marine Monitoring System (PLC in Price List) • Provides visual indication of ECU functionality • Accepts 4 — 20 mA or PWM remote throttle speed input • Marine alarm and protection

Electronic Unit Injectors

• “Drop-in” installation • No threaded fuel connections • High pressure inside injector only • Does not require double wall fuel lines or leak collection device • Injector synchronization not required
