injector resistor box

[crafty]

what does this do? :rflmao: do i need one?

[Mr.Burner]

the box is simply a big resistor.......you need a box to bring down the ohms..or you'll burn up the processor in the computer.
what kind of injectors do you have?

Injectors are classified into two categories.
1. High impedance/resistance (saturated) 12-16 Ohms.
2. Low impedance/resistance (peak & hold) 0.5-6 Ohms.

Saturated injectors require roughly 1-1.5 amps to open the injector. Peak & hold injectors initially needs about 4-6 amps, and once open drops to roughly 2-3 amps to keep it open.

ECU design will dictate the use of one or the other. Most late model cars will use saturated injectors.
