How about a replacement ECU for your older Holley C950? Holley has you covered. HP EFI ECU and harness kits are designed to be used with popular factory EFI engines as an alternative to the factory ECU and harness or as a replacement for your C950 ECU. The HP allows you to accurately control the fuel and ignition of your engine along with additional controls for nitrous, boost or water meth.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eWhen utilizing a trans brake, it is highly recommended to install our trans brake input protection device, Holley P\/N 554-128. This will protect the ECU from any flyback voltage when the transbrake is released. Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water\/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I\/Os than are available. If more I\/Os are required, users should choose the Dominator VMS. Certified to ISO 8846, SAE J1171, and United States Coast Guard Requirements for Ignition Protection and Fire Resistance.\u003cbr\u003eHP EFI ECU, USB Cable, and Software\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003e“Quick Start” ignition and fueling strategy for LS x Engines\u003c\/li\u003e\n\u003cli\u003eData Logger, scalable axes, smoothing, multiple graph view ability, rpe-defined notes fields and more\u003c\/li\u003e\n\u003cli\u003eStrip Chart Real-Time Data Viewer\u003c\/li\u003e\n\u003cli\u003eIntegrated Boost Control - Boost vs Time, Boost vs Gear (Time or RPM), Boost vs RPM, Boost vs Speed, Launch control, Boost launch builder, Over-boost safeties, Boost scramble\u003c\/li\u003e\n\u003cli\u003eTraction Control - Power reduction via timing, nitrous percentage or boost (Requires Davis Technologies Holley Module)\u003c\/li\u003e\n\u003cli\u003e“Quick Start” fueling for all engines\u003c\/li\u003e\n\u003cli\u003eOption for VE based fueling strategy\u003c\/li\u003e\n\u003cli\u003eFuel Map and Learn Function Smoothing\u003c\/li\u003e\n\u003cli\u003eConfigurable User Password Protection\u003c\/li\u003e\n\u003cli\u003eFully Configurable lap top Gauge Panel\u003c\/li\u003e\n\u003cli\u003eEight sequentially driven 8:2 peak and hold injector drivers, capable of driving up to 16 low or high impedance injectors as a standard feature.
