Aeromotive 66136 BoostWorx Returnless PWM Controller for GM ZL1 Fuel Module

Vehicle Fitment

• GM Gen5/Gen6 Camaro ZL1 (OEM fuel pump module)
• C7 Corvette (OEM fuel pump module)
• Cadillac CTS-V (Gen3)
• Pontiac G8 (with Aeromotive Super ZL1 or ZL1-style fuel module conversion)
• Aeromotive Super ZL1 fuel pump module applications
• GM late-model truck fuel modules using brushed fuel pumps

Fitment Notes

• Application is fuel-module specific rather than tied to a single vehicle year range; Pontiac G8 and other non-native applications require a compatible ZL1-style fuel module (e.g., Aeromotive Super ZL1) rather than a direct factory module
• Compatible with either constant fuel pressure or manifold-referenced (boost-responsive) fuel pressure, depending on whether the included MAP sensor is connected

Features

• Stand-alone, OE-type returnless fuel control system
• Supports constant pressure mode or 1:1 manifold-referenced pressure with the included MAP sensor
• Upgrade-ready: install MAP sensor components now to simplify a future supercharger addition
• Works across a wide range of GM Gen5/Gen6 fuel modules, not just factory-matched applications
• Over-temperature shutdown with automatic reset
• Short-circuit protection with automatic reset
• OEM Delphi/Aptiv connectors and cross-linked polyethylene wiring throughout
• Integrates into the OE ECM, keeping factory safety systems functional

Specifications

• Operating Voltage: 10-22V
• Continuous Power Rating: 40A minimum
• Controller Size: 4.5 in L x 3.5 in W x 2 in H
• Fuel Pressure Mode: Constant or manifold-referenced (1:1 with boost)
• Compatible Modules: GM Gen5/Gen6 ZL1, Aeromotive Super ZL1, C7 Corvette, Gen3 CTS-V

Included Components

• 1x BoostWorx Returnless PWM Controller
• 1x MAP Sensor and Mounting System
• Delphi-Sealed Wiring Harness and Hardware

Product Description

The Aeromotive 66136 is a stand-alone returnless PWM fuel pump controller built to drive GM ZL1-style fuel modules with OE-level precision. It's designed to eliminate the need for a traditional return-style regulator and return line by electronically managing pump speed and fuel pressure directly, whether that pressure needs to stay constant or track boost 1:1 through the included MAP sensor.

Because it supports a range of GM fuel modules - from factory Camaro ZL1 and C7 Corvette pumps to the Aeromotive Super ZL1 module used in swap applications like the Pontiac G8 - this controller gives builders a consistent, OE-style fuel delivery experience across multiple platforms rather than needing a separate custom solution for each. Leaving the MAP sensor disconnected keeps the system in simple constant-pressure mode, which also makes it straightforward to add boost-referenced control later if a supercharger gets added down the line.

This kit suits builders working with ZL1-derived fuel modules who want a clean, electronically controlled fuel system without return lines or a separate mechanical regulator, particularly in swap applications like the G8 where a factory-matched module isn't available from GM directly.
