Aeromotive VaporWorx Gen 5 ZL1 Returnless Pulse Width Modulation Fuel Module Controller Kit

The Aeromotive VaporWorx BoostWorx Returnless Pulse Width Modulation Kit (part number 66136) is a complete, stand-alone fuel module control system that delivers OE-quality returnless fuel management for high-performance Gen5 Camaro ZL1, C7 Corvette, and compatible GM fuel pump module applications. Legacy VaporWorx part numbers include BWZL13B, PWZL13B-G8, BWCOYOTE-ZL1, and PWZL13B.

Part 66136 replaces the factory Fuel System Control Module (FSCM) and drives the fuel pump module directly from a compact waterproof controller. The system supports both constant fuel pressure and manifold-referenced (boost-tracked) fuel pressure modes. For constant pressure, simply leave the MAP sensor wiring disconnected. For supercharged or boosted applications, connect the included stand-alone MAP sensor to the intake manifold for a 1:1 manifold-referenced fuel pressure response.

The BoostWorx controller (66136) provides up to a two-thirds reduction in power delivery to the fuel pump at idle and cruise compared to traditional return-type systems, dramatically reducing heat buildup and extending fuel pump module life. Over-temperature shutdown with automatic reset and short-circuit protection ensure the controller can operate indefinitely without damage. A 40A minimum continuous power rating is housed in a compact 4.5 in x 3.5 in x 2 in enclosure. Operating voltage range is 10 to 22 volts, making it compatible with voltage booster systems. If input voltage drops below 10V, the controller automatically shuts down to protect against lean AFR conditions.

Compatible fuel pump modules for use with part 66136 include OEM modules from any Gen5 or Gen6 Camaro, the Aeromotive Super ZL1 module (part 68101), Gen3 CTS-V3, C7 Corvette, and GM late-model truck modules with brushed fuel pumps. The system integrates with the OEM ECM so all safety systems remain functional. All wiring uses cross-linked polyethylene with UL94-rated components throughout, and OEM Delphi/Aptiv connections are used where applicable for maximum reliability.

Frequently Asked Questions

What does the Aeromotive 66136 BoostWorx kit replace in my Gen5 ZL1?
Part 66136 replaces the factory OEM Fuel System Control Module (FSCM) and provides a fully stand-alone PWM returnless fuel pressure control system. It drives the factory or upgraded ZL1 fuel pump module directly without the need for relays, Hobb's switches, or an OEM FSCM.

Does the Aeromotive 66136 work with a naturally aspirated Gen5 Camaro ZL1?
Yes. For naturally aspirated applications, simply leave the MAP sensor wiring disconnected. The controller operates in constant fuel pressure mode, preset to 42 to 60 psi at idle. No MAP sensor connection is needed unless you are running a boosted setup.

Can I use the Aeromotive 66136 with a supercharged ZL1?
Yes. Part 66136 is specifically designed with supercharged applications in mind. Connect the included stand-alone MAP sensor to the intake manifold for manifold-referenced fuel pressure. The controller provides a 1:1 increase in fuel pressure per psi of boost, just like a mechanical return-style regulator, without requiring a separate return fuel line.

What fuel pump modules work with the Aeromotive VaporWorx 66136?
Compatible modules include OEM fuel pump modules from any Gen5 or Gen6 Camaro (all versions), the Aeromotive Super ZL1 module (part 68101), Gen3 CTS-V3, C7 Corvette modules, and compatible GM late-model truck modules with brushed fuel pumps.

Does the Aeromotive 66136 require an inline fuel filter?
No. Aeromotive strongly recommends NOT using an inline filter with OEM fuel modules (except Gen3 Coyote GT500 applications). OEM modules have final filtration built in. Adding an aftermarket inline filter with a check valve can cause dangerous heat-soak overpressure conditions.

What voltage booster is compatible with the Aeromotive 66136?
The 66136 operates from 10 to 22 volts, making it compatible with most external voltage boosters used to increase fuel pump output on high-horsepower builds. Below 10V input, the controller shuts down automatically to protect against lean AFR conditions.

What fuel pressure does the Aeromotive 66136 operate at?
For constant pressure applications, base pressure is typically set between 42 and 60 psi at idle. The controller has a much wider range if needed. For manifold-referenced applications, fuel pressure rises 1:1 with boost pressure above the base setting. Final pressure must always be verified with a mechanical or electronic gauge.

Does the Aeromotive 66136 trigger OBD-II codes or disable safety systems?
No. Part 66136 is designed to integrate with the OEM ECM so all safety systems remain functional. The ECM fuel pump enable wire connects to the controller's turn-on circuit, keeping fuel priming, over-pressure, and safety systems active.

What is the warranty on the Aeromotive VaporWorx 66136?
Aeromotive covers part 66136 with a 1-year warranty from the date of purchase. Warranty support requires proof of purchase and can be initiated by calling Aeromotive at 913-808-2376, option 3.

Is the Aeromotive 66136 a bolt-in for a Pontiac G8 fuel system?
Yes. Legacy VaporWorx part number PWZL13B-G8 is the G8-specific wiring version of the same controller now sold as part 66136. The G8 application uses a blue wire connecting to the OEM fuel pump positive (grey wire). The core controller is the same as for Gen5/6 Camaro applications.
