Aeromotive VaporWorx Returnless ZL1 Pulse Width Modulation Kits

Aeromotive VaporWorx returnless PWM kits for ZL1 fuel pump modules have everything needed to provide a standalone, OE-type returnless fuel system with constant or manifold referenced fuel pressure.

When used with the popular and affordable GM Gen5 ZL1 Camaro, C7 Corvette, Aeromotive Super ZL1, and many other GM-compatible fuel pump modules, these systems will provide constant pressure or any base pressure with a 1:1 manifold referenced (supplied MAP sensor based) fuel pressure—operating like a mechanical fuel pressure regulator would with the ECM calibrated in the same manner.

The simplicity of these kits comes with connecting the supplied standalone MAP sensor to the pressurized side of the intake manifold, just like connecting a boost gauge or manifold referenced fuel pressure regulator. For constant fuel pressure simply leave the MAP sensor portion of the kit disconnected.

VaporWorx ZL1 controllers feature:

* Everything needed electrically to drive the fuel pump module--no relays, external regulators, or return lines are required
* Unmatched low fuel level capability
* Up to a 2/3 reduction in power to the fuel module during idle and cruise vs. traditional systems
* 40-amp minimum continuous power rating in a compact controller package
* Over-temperature shutdown with automatic reset
* Short circuit protection that will operate indefinitely without damage
* OEM Delphi/Aptiv connections for terminals, seals, and connector bodies
* All cross-linked polyethylene wiring
* UL94 rated components used throughout
* Integrates into the OE ECM to allow all safety systems to remain functional
* 10 to 22 V operating capacity
-- Can be used with voltage boosters
-- Lower than 10 V applied to the turn on circuit will cause controller shutdown to protect from an AFR lean condition
* Billet aluminum VaporWorx MAP sensor bracket and 3bar pressure sensor
