PH Injector Driver Module

SymTech Labs' Peak & Hold (PH) Fuel Injector Driver Module efficiently drives low impedance, or "peak and hold," fuel injectors. Designed for use with MegaSquirt EMS systems, the SymTech Labs PH Injector Driver Module supplants the injector drivers on either v2.2 or v3.0 boards.

Low impedance fuel injectors are preferred over high impedance, or "saturated," fuel injectors for their precision and quick response time. The SymTech Labs PH Injector Driver Module is the only way to accurately control these injectors and meet your engine's demanding fueling needs. The PH Driver offers four independent channels, one for each fuel injector, perfect for use with sequential injection-enabled MS2/Extra or MS3 firmware. For applications with more than four fuel injectors, multiple boards can be installed.

There are no tricky PWM settings to calibrate, since the onboard chips limit current draw through each injector on the fly. The PH Injector Driver Module compensates for low voltage conditions (cold weather, startup, etc.), and even eliminates the radio frequency interference (RFI) characteristic of the standard MegaSquirt fuel injector drivers. The PH Injector Driver Module is optimized for use with 4A peak and 1A hold low impedance fuel injectors. The board comes fully assembled and contains virtually all surface mount devices (SMD), which are less prone to failure due to vibration. The module is designed to fit a standard width (~4") MegaSquirt ECU enclosure.
