Aeromotive Part Number: 66101
Legacy VaporWorx Part Number: PWCTSVLSA

The PressureWorx CTS-V LSA fuel module control system has everything needed to provide a stand-alone, OE-type returnless fuel system that meets the GM LSA crate engine fuel pressure requirements.

This kit is intended to be used with the GM LSA ECM and wiring kit for the LSA engine only. For other applications: BoostWorx Returnless Pulse Width Modulation Kit, CTS-V Fuel Pump Module

When used with the CTS-V fuel module the system will provide the needed manifold referenced (MAP sensor based) fuel pressure that cannot be met with traditional return type pressure regulators.

Suggested compatible fuel modules:

• Gen2 CTS-V: GM Genuine MU1886 or M10235
• Note that the GM Genuine fuel pump module is no longer available. For a pump with similar performance, please look here at the Aeromotive Super ZL1: (
  • Super Fuel Module, Gen5 Camaro ZL1
  • BoostWorx Pulse Width Modulation Fuel Module Controller, ZL1 LSA Applications

The OEM fuel level sensor is not needed for VaporWorx controller function but it may be used. It is a popular option for gauges that have either a 40F-250E ohm range or those with a custom programming option.
When combined with the CTS-V fuel module a 750hp supercharged fuel pumping system is easily obtained.

This setup has been used in hundreds of applications with good success, easier fitment, and low overall cost.

It is strongly suggested to NOT use an inline filter with with OEM fuel modules except Gen3 Coyote GT500. Final filtering is built in. Some aftermarket fuel filters have a built-in check valve which will cause a heat-soak related overpressure condition that will lock up port type fuel injectors.

The BoostWorx CTS-V LSA 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. 750hp capable.
• Unmatched low fuel level capability when used with an OEM style fuel module.
• Calibrated specifically for the LSA crate engine controller.
• A 50% 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/Aptiv connections for terminals, seals, and connector bodies where appropriate.
• All cross-linked polyethylene wiring.
• Single 20' wiring harness from the controller to the fuel module.
• 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.
