RC Engineering is the world's leading supplier of made-to-order, high-performance, electronic fuel injectors. RC injectors are available for a wide range of automotive, motorcycle and marine engines used in high-performance or racing applications.
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.
Note: Most late model Honda/ Acura applications OBD1+ will use saturated injectors.
