Thinking about going supercharged someday? You will be ready to go by installing the MAP sensor components, so the upgrade pathway is easy.\u003c\/p\u003e\n\u003cp\u003eWhen used with the GM CTS-V2 and compatible fuel pump modules, this system will provide constant pressure or any base pressure with a 1:1 manifold referenced (supplied MAP sensor based) fuel pressure. It will operate like a mechanical fuel pressure regulator would with the ECM calibrated the same way. The fuel injector does not know if the fuel supplied is pumped by a return or returnless system. \u003cstrong\u003eEvery OEM today, even on the highest horsepower models, use returnless PWM control systems. \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf manifold referenced fuel pressure is needed simply connect the supplied stand-alone MAP sensor to the pressurized side of the intake manifold, just like connecting a boost gauge or manifold referenced fuel pressure regulator.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSuggestion:\u003c\/b\u003e If your car is properly running with a constant fuel pressure ECM calibration, then changing to MAP referenced fuel pressure is usually not needed or worth the extra expense to recalibrate the fuel maps in the ECM. Just leave the controller MAP wiring\/sensor\/mounting bracket disconnected. \u003cbr\u003eBase fuel pressures at idle are typically between 42-60psi, but the VaporWorx controller has \u003cb\u003emuch greater range\u003c\/b\u003e if needed.\u003c\/p\u003e\n\u003cp\u003eFor a constant fuel pressure system a 42-60psi pressure is typically used, so do not use the supplied MAP sensor wiring, sensor, or mounting bracket. For supercharged applications manifold referenced fuel pressure is often needed.\u003c\/p\u003e\n\u003cp\u003eAeromotive recommends using a MAP referenced fuel pressure on large fuel injected systems to allow injector duty cycles to be increased at idle\/cruise, hence allowing greater injector duty cycle calibration capability. MAP referenced fuel pressure also reduces the at idle\/cruise power requirements by approximately 2\/3 vs. traditional return type fuel systems.\u003c\/p\u003e\n\u003cp\u003eFuel pressure for the CTS-V2 fuel module should be limited to 65psi maximum when using the OEM internal safety valve. Above this pressure the OEM internal safety valve will start to open, hence limiting further pressure increase.\u003c\/p\u003e\n\u003cp\u003eIt is strongly suggested to NOT use an inline filter with OEM fuel modules except Gen3 Coyote GT500. Final filtering is built in. Some aftermarket fuel filters have a built-in check valve which will cause a heat-soak related overpressure condition that will lock up port type fuel injectors.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThis fuel pump module Controller system includes these standard features:\u003c\/b\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEverything needed electrically to drive the fuel pump module.
