8 x Injection drivers, 8 x Ignition drivers, integrated lambda controllers. Data Logging: 2 GB internal memory. Communication: 3 x CAN, 1 x Ethernet.
The primary unit for fuel, air, and spark management.
Fleet electrification engineering firms transitioning from prototype to small-scale fleet deployment. Summary Checklist for Choosing an ECU A higher clock speed (e.g.
The EDC16 was the mass-market transition to full digital diesel control. While harder to find than component datasheets, the system overview document is a masterclass in integration.
Direct injection drivers for up to 8 cylinders, 4 x lambda inputs. Data Logging: 128 MB flash memory up to 2 kHz sampling. Communication: 2 x CAN 2.0B, Ethernet.
4 x Injector outputs, 4 x Ignition outputs, 4 x Extra analog inputs. Data Logging: 128 MB internal memory.
Measured in MHz. A higher clock speed (e.g., 80MHz to 300MHz) allows for faster internal calculations. This is crucial for high-RPM engines where calculation cycles are limited.
