FAQ: What are the differences between low impedance/peak & hold and high impedance/saturated injectors?

ERIKC Answer:The older fat body style low impedance injectors (1.5 to 4.0 Ohm) used to have faster open and close times due to the type of electrical signal pattern emitted by an ECU equipped with proper P&H signal transmitters. This “Peak and Hold” injector signal typically uses a high (4 amp) initial current to open the injector, and which reduces to a lower (1 amp) current to keep the injector open until the pulse ends. Since this method put less total current into the coil, the coil heated up less and was therefore more reliable. Since the “hold” or lower current part of the signal has created a weaker magnetic field, the injector will also close more quickly.

Does my ECU create a P&H signal? - Read “Why does my car have a resistor pack?”

ERIKC Answer:If you are running a stock (OEM) ECU, the most likely ERIKC Answer is NO! While most recently produced cars left the factory floor with high impedance injector driven by saturated signals from the OEM ECU, there are a few cars (for example the US Toyota Supra TT or the Mitsubishi Evo 8 & 9 or all the DSM Turbo cars [Eclipses, Talons, Lasers]) that came with low impedance injectors that should have been driven with P&H signals.
