FUEL 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.

- Flyback Voltage Clamp 70V
- Max Peak current 8A
- Max Hold current 4A
- Total current limited to 10A per output
Protection
- Over current / Short to Battery protection
- Electrostatic discharge (ESD) protection
- Flyback Voltage Clamp

Saturated Injector Control

- Flyback Voltage Clamp 70V
- Total current limited to 10A
Auxiliary Injection Mode
- Unassigned Fuel channels can be used to switch or modulate resistive and inductive load.
- Flyback Voltage Clamp 70V
- Total current limited to 10A
