Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector. These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures. They are based on the same design as the popular FI114992 80 lb/hr DEKA IV (.
