The Solid-State Relay Upgrade Kit changes that: it converts your fuel pump system to full PWM control, combining Precision Raceworks' Solid-State Relay Fuel Pump Interface Module with a high-quality solid-state relay in a single plug-and-play kit. Instead of hammering the pump at full output regardless of demand, the pump only works as hard as the engine actually needs.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended frequency:\u003c\/strong\u003e 200 Hz — this is the sweet spot for optimal control and stability when paired with a Motiv Re|Flex+ controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent handling:\u003c\/strong\u003e ~20A continuous, up to 80A burst — sized correctly for Walbro pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-play compatibility:\u003c\/strong\u003e Designed for PRW's V2 Pump Activation Harness (identifiable by the Deutsch 4-pin connector near the pump connector) — no wiring modifications needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne kit per pump:\u003c\/strong\u003e Each pump being PWM-controlled needs its own kit — a dual-pump AFS.800 setup, for example, needs two kits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal fitment:\u003c\/strong\u003e Not vehicle-specific — works with any PRW pump activation harness setup, BMW or otherwise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy PWM over simple relay control:\u003c\/strong\u003e Cooler fuel (less heat soak at low duty cycles), less pump wear (progressive ramp-up vs. constant full-output cycling), quieter operation, more stable system pressure, tunable output scaled to boost\/RPM\/load, and cleaner electronics with less interference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Solid-State Relay Fuel Pump Interface Module\u003c\/li\u003e\n\u003cli\u003e1x automotive-grade solid-state relay\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal product, not tied to a specific vehicle or engine platform\u003c\/li\u003e\n\u003cli\u003eDesigned to work with PRW's V2 Pump Activation Harness across any application (B58, S58, or otherwise)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVehicle Application\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eUniversal — not vehicle-specific.
