FAQ
What is the Aeromotive 66108?The Aeromotive 66108 is a Pulse Width Modulation fuel module controller kit designed specifically for the GM LSA crate engine ECM and wiring, providing OE style returnless fuel pressure control for ZL1 and CTS-V supercharged applications.
What vehicles use the LSA engine that this controller supports?The GM LSA supercharged V8 was used in the 2012-2015 Chevrolet Camaro ZL1 and the 2009-2015 Cadillac CTS-V, and is also a popular crate engine swap option.
Which fuel modules work with the Aeromotive 66108?It is compatible with the GM Genuine ZL1 Gen5 fuel module (M10081 or MU2101 with OEM fuel level sensor) and the ZL1 Gen6 fuel module (MU2369 with fuel level sensor).
How much horsepower can this controller support?When combined with a compatible Gen5 or Gen6 ZL1 fuel module, the system can support up to 650 horsepower on a supercharged combination.
Does this kit require cutting or splicing into the factory harness?No. The kit is designed as a stand alone system with its own dedicated 20 foot wiring harness and OEM style connectors that integrate with the LSA ECM without splicing into unrelated factory wiring.
What type of fuel pressure control does this provide?It provides manifold referenced, MAP sensor based fuel pressure control rather than a fixed mechanical pressure setting, matching OE returnless fuel system behavior.
Does the controller include safety protections?Yes. It includes over temperature shutdown with automatic reset and built in short circuit protection, and it integrates with the OE ECM safety systems.
What is the operating voltage range for this controller?The controller operates across a 10 to 22V range, matching typical automotive electrical system conditions including cranking and charging voltage swings.
Install Instructions
- Disconnect the vehicle battery before beginning installation
- Mount the PWM controller in a secure, accessible location in the engine bay
- Connect the pre-wired 20 foot harness to the LSA ECM connection points using the included OEM style connectors
- Connect the controller to the compatible ZL1 Gen5 or Gen6 fuel module
- Verify all ground and power connections are secure
- Reconnect the battery and confirm proper fuel pressure operation before starting the engine
Aeromotive
Aeromotive has been the standard for high-performance fuel delivery since 1994, engineering fuel pumps, regulators, filters, and complete fuel system kits trusted by professional racers and serious street car builders. If your engine is making big power — whether on forced induction, nitrous, or a naturally aspirated high-displacement build — Aeromotive's catalog has the components to keep fuel supply ahead of demand under every condition.Popular UpgradesThe Aeromotive Stealth 340 and Phantom in-tank fuel pump systems are top sellers for builds that demand consistent flow without external pump mounting. The A1000 external fuel pump remains a proven choice for high-horsepower carbureted and EFI applications. Billet fuel pressure regulators from Aeromotive allow precise adjustability for return-style systems, and complete stealth fuel system kits offer a clean, all-in-one solution for builders who want maximum reliability from a single supplier.What flow rate do I need for my power le...

Fuel Delivery
A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

Fuel Pumps
A fuel pump is the foundation of every fuel system, and matching pump flow capacity to your engine's actual demand is one of the most critical decisions in any EFI or performance build. Undersized pumps cause lean conditions under hard acceleration that damage pistons and injectors, while oversized pumps can pressurize the fuel system beyond regulator capacity and require additional return plumbing to handle excess flow. Modern in-tank brushless pump designs from Walbro, TI Automotive, and Aeromotive deliver high flow rates with lower current draw and longer service life compared to older brush-style commutator designs. Diesel lift pumps serve a different function, providing pressurized supply to the high-pressure injection pump while also filtering water and particulates, and selecting the right lift pump for your diesel platform directly affects injection system longevity. Popular Upgrades Top-selling fuel pumps include the Walbro 255 LPH and 450 LPH in-tank pumps for popular turb...
