AEM’s external Peak & Hold Injector Driver module allows ECU’s that have a saturated injector drive circuit to trigger low impedance injectors with a true 4/1 Peak & Hold injector drive circuit.
AEM’s Peak & Hold Injector Driver contains 10 independent injector drive channels. Each channel supplies full battery voltage to a fuel injector for rapid current rise, in order to produce positive injector opening. When load current reaches 4.1A (amps), the injector driver reduces the load current to 1.1A and operates as a constant current source. This condition holds the injector open, and reduces system power dissipation. If the current fails to reach 4.1A within 5mS, the driver module automatically reduces the load current to 1.1A.
Installation is straightforward. Users simply hook the injector trigger wires from an ECU to the module, and then hook the output wires from the module to your injectors. Any number of channels can be used from one to 10.
