TheĀ PressureWorx Auto-On dual fuel pump control system has everything needed to provide a stand-alone, OE-type returnless fuel system.
This system is to be used with dual fuel pumps (not OEM modules) to provide a 1:1 manifoldĀ referenced (MAP sensor based) fuel pressure. 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 orĀ returnlessĀ system.
The standardĀ PressureWorxĀ option is tuned for the GM LSA 3bar 12592525Ā sensor.Ā Ā Other sensor tunes are available at no charge. The MAP sensor tune in theĀ PressureWorxĀ controller must match the MAP sensor so that the proper 1:1 pressure rate change can occur.
Base fuel pressures at idle are typically 42psi, but theĀ VaporWorxĀ controller has much greater range if needed.
TheĀ VaporWorx PWM Auto-On Dual Pump system monitorsĀ the MAP sensor to provideĀ a MAP referenced fuel pressure and to turn on the second pump. TheĀ VaporWorxĀ controller has aĀ Pump 2 output that turns on at 2psi of boost. NoĀ HobbāsĀ switches, relays, or other devices are needed.
For 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,Ā additionalĀ 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 Rickās Tanks pump hats, they have a jet that can be installed to perform this bypass.
Pumps supported include:
- TI F90000267 (0.041ā bypass) and F90000285 (0.051ā bypass) pumps.
- Stealth 340 pumps with 0.025ā bypass.
- Contact us for other pump applications.
TheĀ PressureWorx 3bar Auto-On Fuel Module Controller system includes these standard features:
- Everything needed electrically to drive the fuel pump module. No relays, external regulators, or return lines needed.
- Up to 2/3 reduction in power to the fuel module during idle and cruise vs traditional systems.
- 80A minimum continuous power rating in a compact controller package. Total size 4.5āL x 3.5āW x 2āH.
- Over-temperature shutdown with automatic reset that will operate indefinitely without damage.
- Short circuit protection that will operate indefinitely without damage.
- OEM Delphi/Aptiv connections for terminals, seals, and connector bodies where appropriate.
- All cross-linked polyethylene wiring.
- UL94 rated components used throughout.
- Integrates into the OE ECM to allow all safety systems to remain functional.
- 10-22v operating capacity. Can be used with voltage boosters. The preferred booster is the JMS FuelMax. Lower than 10v applied to the turn on circuit will cause controller shutdown to protect from an AFR lean condition.
- Must be used in manifold referenced fuel pressure mode.
- Second pump turn-on set to 2psi boost.
- Can be used with Fore Innovations and similar dual pump arrangements.
- Can be used with Rickās Tanks dual pump hat with PWM modifications. Rickās to provide the needed bypass jet based on the pumps used.
