Aeromotive 66137 BoostWorx PWM Controller for Ford Coyote Godzilla ZL1 Pump

Vehicle Fitment

• Ford Coyote (all generations), GT500, Godzilla, and Megazilla crate engine applications running the Ford Controls Pack, paired with a GM Gen5/Gen6 Camaro ZL1 fuel pump module

Fitment Notes

• Application is engine/fuel-module specific, not tied to a fixed vehicle model year; commonly used in Ford Coyote retro-swap builds using a GM ZL1 fuel module as the pump source
• For applications running a Ford GT or GT500 Mustang factory fuel module instead of the GM ZL1 module, Aeromotive specifies P/N 66131 or 66133 in place of this kit
• Not recommended for use with an inline fuel filter on OEM fuel modules, with the exception of the Gen3 Coyote GT500 module - most factory modules already include final filtering

Features

• Stand-alone, manifold-referenced, OE-type returnless fuel control system
• Supports up to 750 HP naturally aspirated / 650 HP supercharged when paired with the Gen5 ZL1 fuel module
• Manifold-referenced fuel pressure changes 1:1 with boost, up to 25 psi
• Also operable in constant-pressure mode by disconnecting the MAP sensor wiring
• Proven in large numbers of Coyote-swap builds using the low-cost ZL1 fuel module
• No relays, external regulators, or return lines required
• OEM Delphi/Aptiv-style connectors and cross-linked polyethylene wiring
• Integrates into the OE ECM to keep factory safety systems functional

Specifications

• Base Fuel Pressure: typically 42-60 psi (wider range available)
• Boost Reference: 1:1 manifold-referenced, up to 25 psi
• Power Rating: 750 HP naturally aspirated / 650 HP supercharged (with Gen5 ZL1 module)
• Compatible Fuel Pump Module: GM Gen5/Gen6 Camaro ZL1
• Compatible Engine Control Packs: Ford Coyote, GT500, Godzilla, Megazilla

Included Components

• 1x BoostWorx PWM Fuel Module Controller
• 1x Stand-Alone MAP Pressure Sensor and Mounting Hardware
• Wiring Harness with OEM-style Sealed Connectors

Product Description

The Aeromotive 66137 is a stand-alone PWM fuel module controller built specifically to run Ford Coyote-family Control Packs - including GT500, Godzilla, and Megazilla crate engines - using a GM Gen5/Gen6 Camaro ZL1 fuel pump module instead of Ford's own factory module. It's a popular combination in retro-swap builds where the ZL1 module offers a cost-effective, high-capacity fuel source.

Functionally, it behaves like a manifold-referenced mechanical fuel pressure regulator: connect the included MAP sensor to the pressurized side of the intake manifold, set your target base pressure, and the controller manages fuel delivery through the ZL1 module accordingly. When paired with the Gen5 ZL1 module, the setup is rated to support up to 750 HP naturally aspirated or 650 HP under boost, covering a wide range of Coyote-swap power goals.

This kit suits builders doing a Ford Coyote, Godzilla, or Megazilla crate engine installation who want to avoid sourcing Ford's OEM fuel module and instead take advantage of the widely available, lower-cost GM ZL1 pump module - without giving up OE-style returnless fuel delivery behavior.
