2.0 Injection


The ECU can control both modes of injection: Saturated and Peak & Hold.
Peak and Hold – 12 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 12 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.
