AEM’s external Peak & Hold Injector Driver module allows ECUÂ’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.
