Peak and Hold Injector Drivers
Injectors 1-6 include Peak (4 amps) and Hold (1 amp) injector drivers. These drivers may
be used with peak and hold or saturated type injectors. The factory Nissan wiring harness
may contain a resistor pack to prevent excessive current when using low-impedance
injectors with the stock ECU. With the 30-6620 installed, users can elect to remove and
bypass the OEM resistor pack for more precise control of low-impedance injectors.
Please note that the injector response time will be different with and without the factory
injector resistor pack. If the OEM resistor pack has been removed and bypassed, please
use the correct battery offset wizard for your injectors. Most battery offset wizards will
specify <P&H DRIVER> if they are intended for use without a resistor pack.
Wiring accessories to the EMS:
Please follow this suggested wiring diagram when adding accessories such as UEGO
gauges, MAP sensors, IAT sensors, or switches for use with the EMS. Note that wire
polarity is not important for the Air Temperature sensor.
