injector FAQ

FAQ: Why do I have a (injector) resistor pack (box) in my car?

ERIKC Answer:The resistor pack is installed to ‘fool’ your ECU into thinking it is driving high impedance injectors. Vehicles that have low impedance injectors AND resistor packs have ECUs that use a saturated signal to operate low impedance injectors.

You may know, or have read earlier in our FAQ How do I know if my injector is low impedance or high impedance? that low impedance injectors are designed to be driven by peak and hold signals. Most of the OE manufacturers that produced cars with low-Z injectors chose a “workaround” to using the low-Z injectors since it wasn’t cost effective to produce an ECU with the necessary circuitry and injector drivers to produce these P&H signals for the few high performance cars that needed it.

FAQ: What type of fuel can I use in my injector?

ERIKC Answer:Typically you can use just about any fuel in today’s injectors (see 2150cc exception below). While the injector will operate normally with just about any fuel, you do have to take some precautions with certain fuels.
