Description

PressureWorx 3bar PWM ZL1/LS3 fuel module control system.

The PressureWorx fuel module control system has everything needed to provide a stand-alone, OE-type returnless fuel system. When used with the low-cost GM, Ford, and many other OEM returnless PWM controlled fuel modules the system can provide a constant pressure or any base pressure with a 1:1 manifold 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 or returnless system. If manifold referenced fuel pressure is to be used, the standard PressureWorx option is tuned for the GM LSA 3bar 12592525 sensor. Other sensor tunes are available at no charge. The MAP sensor tune in the PressureWorx controller must match the MAP sensor so that the proper 1:1 pressure rate change can occur.  

Suggestion: If your car is already running with a constant pressure tune and all you need is a larger volume fuel system, changing to MAP referenced fuel pressure is not needed or worth the extra expense to retune the fuel maps in the ECM.  

The PressueWorx Fuel Module controller will also work well with these fuel modules. Fuel pump plug wiring changes may be needed: 

  • Gen5 SS/ZL1 
  • CTS-V3 
  • GM Trucks 
  • C7 Corvette (all models.) 
  • Ford Coyote Mustang (all generations.) 
  • Ford FPDM Mustangs (early 2000’s and forward using OEM FPDM equipped systems.) 

Base fuel pressures at idle are typically between 42-60psi, but the VaporWorx controller has much greater range if needed. For a constant fuel pressure system, like that for all GM naturally aspirated LS and LT series engines, a 60psi pressure is typically used. For supercharged applications either a constant or MAP referenced fuel pressure can be used depending on how the ECM is tuned. VaporWorx 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 tuning capability. MAP referenced fuel pressure also reduces the at idle power requirements by 2/3 vs traditional return type fuel systems. 

All OEM type fuel modules will not work on carbureted applications. A minimum 43psi is needed for proper WOT operation.  

When combined with the Gen5 Camaro ZL1 fuel module, a 750hp naturally aspirated / 650hp supercharged fuel pumping system is easily obtained. This setup has been used in thousands of applications with good success, easier fitment, and low overall cost. However, the PressureWorx Controller will work with any Gen5/6 fuel module.  

The PressureWorx 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.
    • Unmatched low fuel level capability when matched with an OEM style fuel module.
    • Up to 2/3 reduction in power to the fuel module during idle and cruise vs traditional systems.  
    • 40A minimum continuous power rating in a compact controller package. Total size 4”L x 2.1”W x 1-5/8”H.  
    • Over-temperature shutdown with automatic reset that will operate indefinitely without damage.  
    • Short circuit protection that will operate indefinitely without damage.  
    • OEM Delphi/Aptive 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.  
    • Can be used in constant or manifold referenced fuel pressure modes. Manifold referenced suggested to further reduce electrical demand and for vehicles with large, 100#/hr+, injectors.
