2.0 Injection


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
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.
