The ECU can control both modes of injection: Saturated and Peak & Hold.

Peak and Hold – 8 x channels

When using low impedance injectors (< 5 Ohms) the ECU uses a switch mode current limiting technique to minimise heat dissipation in the Injector. This gives better injector control and helps maximize injector life by lower its operating temperature.

Independently configurable Peak and Hold currents up to 8 cylinders

• Max Peak current 8A
• Max Hold current 2A
• Current limited to 10A.
• Flyback Voltage Clamp: 60V.

Saturated

Required when injector resistance is greater than 5 Ohms.

Current limited to 5A.

• Flyback Voltage Clamp: 60V.

Auxiliary Fuel Mode

Unassigned Fuel channels can be used to switch or modulate resistive and inductive loads.

Sink continuous current 5A, current limit 8A.

• Flyback voltage clamp: 60V.
• Maximum Frequency: 5kHz

Protection

• Over current / Short to Battery protection
• Electrostatic discharge (ESD) protection
• Flyback Voltage Clamp: Dependent on Flyback pin configuration. Normally battery constant power.

Ignition Control – 8x channels

8 Channels Sequential/Wasted Ignition or 4  Leading/4 Trailing Ignition.

• Independent switchable pull-up resistor control on channels 1 to 8.
• Adjustable source current;  35mA at 5V or  70mA  at 8.2V for high current mode

Auxiliary Ignition Mode

Unassigned Ignition channels can be used to switch or modulate resistive and inductive loads.

Sink continuous current 1A, current limit 3.0A.

• Flyback voltage clamp: 40V.
• Maximum Frequency: 5kHz

Protection

• Over current / Short to Battery protection
• Electrostatic discharge (ESD) protection
