Deatschwerks Set of 6 550 cc/min injectors (part no. 42M-01-0550-6, low impedance)
Set of 6 550cc Low Impedance Injectors for Nissan Skyline GTR RB26DETT 89-02
IMPORTANT NOTE: Offset data above is for use with TRUE peak and hold injector drivers. Most OE's ECU's that drive OE low impedance injectors do not use true peak and hold injector drivers. Instead, they install resistors in-line with the injectors and drive the injectors with saturated (high impedance) injector drivers
The shift in the curve (driver type B) between 14 and 15 volts is the result of using a 2.2 ohm injector with a 4 amp/1 amp peak and hold drive circuit and 4 ms forced hold timer. There is approximately 1 ohm extra circuit and coil self heating resistance at 4 amps causing the injector drive circuit to go into hold mode above 14 volts. A 2 amp peak and hold drive circuit (ie type A driver) will always go into hold mode.
