Quantity

The KV8 can control both modes of injection: Saturated and Peak & Hold up to 8 channels.

Peak and Hold Injector Control

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

Flyback Voltage Clamp 70V

Max Peak current 8A

Max Hold current 4A

Total current limited to 10A per output

Saturated Injector Control

Required when injector resistance is greater than 5 Ohms.

Auxiliary Injection Mode

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