Click here if you are using \u003cb\u003eOEM fuel modules\u003c\/b\u003e.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eFuel System Control Module (FSCM), Fuel Pump Pressure Module (FPPM), Fuel Pump Driver Module (FPDM), and Fuel Pressure Control Module (FPCM) are slightly different names for the same device. They electronically control the fuel pressure by pulsing the fuel pump on\/off, typically at \u003cu\u003e25khz\u003c\/u\u003e, hence turning it into a variable speed pump. The ECM commands a pressure, the FSCM provides the heavy lifting to power the pump, and the fuel pressure sensor provides feedback to the ECM. This excellent closed-loop control system is used to help adjust injector duty cycle based on actual injector delta pressure. No aftermarket system offered can perform this function. So, why get rid of it when “Going Big” with new pumps if it can still be useful?\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe newest GM, Ford, Mopar, BMW, etc. engines and electronic control systems are some of the greatest automotive technology available today. But, like all gearheads, we usually want more, right?\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eUnfortunately, the OEM FSCM’s used in both the late model OEM car and in crate engine offerings leaves much to be desired when more fuel is needed. The OEM FSCM can handle one high-power pump, but not multiple pumps. For example, the GM FSCM for Gen5 systems has “\u003cu\u003e22A\u003c\/u\u003e Max” labeled on the internal circuit board. A single TI Automotive \u003cu\u003e525lph\u003c\/u\u003e pump will require that much power. So, when trying to add another pump they will not be able to support the needed power and will start throwing MIL codes. So, how can more than one pump be used while keeping full closed-loop control of the FSCM?\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe Ally kit allows the FSCM to control the primary pump while the VaporWorx Ally Auto-On controller “Piggybacks” and takes care of the other pumps. The Ally Auto-On does not turn on the other pumps until approximately \u003cu\u003e5psi\u003c\/u\u003e\u003cspan\u003e \u003c\/span\u003eof boost by using a supplied stand-alone MAP sensor to act as the turn-on trigger.  No bulky mechanical pressure switches here.\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0806\/0275\/9468\/files\/66187_switch.png?v=1754932562\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWhen used in this way there is sufficient power for all fuel pumps while maintaining the FSCM CAN feedback and diagnostics. All pumps will effectively be under the control of the FSCM.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWith just a single \u003cu\u003e20ga\u003c\/u\u003e wire to attach to the FSCM fuel pump pulsed wire, and the before mentioned MAP sensor wiring, hookup is straightforward. With that done, it’s just battery power in, and fuel pump power out. No Hobb’s switches, no relays, no on\/off switches, etc.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eA feature that the Ally controller offers that is not available on other control types is a progressive pump ramping strategy. In short, the FSCM’s have power envelopes they are expecting to work in. If the power is too high or low, it sets MIL codes. To reduce the chances of setting a MIL code the VaporWorx controller will “follow behind then outrun” the primary pump. This allows the VaporWorx controller, with the \u003cu\u003e2\/3\u003c\/u\u003e pumps attached, to provide less fuel output at low demand, and more fuel output than the primary FSCM pump. This helps keep the FSCM power load withing the programmed power ranges, hence reducing the chances of a MIL code.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eAnother advantage to the Ally is a soft-start feature that reduces pressure spikes when the \u003cu\u003e2\/3\u003c\/u\u003e pumps turn on. Traditional relay\/solid state switches turn the pumps on full speed, often resulting in a fuel pressure spike. When the VaporWorx controller turns on the \u003cu\u003e2\/3\u003c\/u\u003e pumps there is a very short soft-start ramp in to help reduce pressure spikes.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eFeatures of the kit include:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul type=\"disc\"\u003e\n\u003cli class=\"MsoNormal\"\u003eEverything needed electrically to drive the \u003cu\u003e2\/3\u003c\/u\u003e fuel pumps.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eTypical \u003cu\u003e67%\u003c\/u\u003e reduction in power to the fuel pump during idle and cruise vs traditional systems means long OEM pump life expectancy.\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\n\u003cu\u003e50A\u003c\/u\u003e minimum continuous power rating in a compact controller package.
