It will act just like a mechanical fuel pressure regulator would with the ECM tuned in the same manner. The fuel injector does not know if the fuel supplied is pumped by a return or returnless system.\u003c\/p\u003e\n\u003cp\u003eThe standard kit is calibrated for 1:1 fuel pressure change vs. manifold pressure, the same as a traditional mechanical fuel pressure regulator.\u003c\/p\u003e\n\u003cp\u003eBase fuel pressures at idle are typically 42psi, but the VaporWorx controller has much greater range if needed.\u003c\/p\u003e\n\u003cp\u003eThe Auto-On Pump control system monitors the MAP sensor to provide a MAP referenced fuel pressure and to turn on the second pump. The VaporWorx controller has a Pump 2 output that turns on at 4psi of boost. No Hobb's switches, relays, or other devices are needed.\u003c\/p\u003e\n\u003cp\u003eFor pumps to operate in closed loop PWM mode, some fuel must pass through the pumps while running. This fuel volume is more than what the engine needs at idle and cruise. So, additional bypass fuel must be added. In the OEM fuel module this fuel is put to work driving the multiple transfer pumps that move fuel into the module reservoir. On aftermarket pump hangers the single hole used to drive the transfer pump needs to be increased or provided by some other method. For Rick's Tanks pump hats, there is a jet that can be installed to perform this bypass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe fuel pumps supported by this PWM Controller is Aeromotive's line of 340 LPH In-Tank Fuel Pumps.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThe 3bar Auto-On Fuel 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.
