Description
Full-Cylinder Control for Two Specific Buick Applications
The Recontrol-X RC-AFM-DFM-01-44 is a vehicle-specific OBD-II AFM/DFM Disabler supplied for two distinct Buick applications:
2006-2008 Buick Terraza with the 3.9L V6
and
2018 Buick Regal GS with the 3.6L V6.
This is important because the two vehicles are from completely different generations and vehicle segments. The Terraza is a Buick minivan equipped with GM's 3900 V6 family, while the 2018 Regal GS uses the newer 3.6L LGX V6.
They should therefore never be described as if they share one identical engine or model-year range.
2018 Regal GS — OEM-Verified Active Fuel Management
The 2018 Buick Regal GS 3.6L V6 is the strongest technically verified application within this SKU.
Buick's official 2018 Regal specifications identify the GS-exclusive engine as a 3.6L V6 DI DOHC, while GM's 2018 Regal technical bulletin identifies that powertrain as the LGX 3.6L V6 with VVT, Active Fuel Management and Stop/Start.
GM's technical explanation is even more specific.
When AFM is active, the system controls the valvetrain on cylinders 2 and 5, allowing those cylinders to be deactivated under appropriate engine load conditions. That means the V6 can operate temporarily with four active cylinders before returning to full six-cylinder operation when required.
For a 2018 Regal GS owner who prefers consistent six-cylinder operation, that gives the Recontrol-X module a clear purpose:
keep the compatible AFM system from entering reduced-cylinder operation.
AFM and Auto Stop/Start Are Different Systems
This SKU is particularly vulnerable to incorrect marketing because the source filenames currently call the product an:
“Auto Start-Stop Eliminator.”
That terminology must not be copied into the finished product listing.
GM specifically describes the 2018 Regal GS 3.6L engine as having both AFM and Stop/Start, demonstrating that they are two separate technologies.
Active Fuel Management changes how many cylinders are operating while the engine continues running.
Auto Stop/Start can shut the engine down when the vehicle is stopped under qualifying conditions and restart it afterward.
The supplied product itself is labeled AFM/DFM Disabler, so the customer-facing page should remain focused on cylinder-management control rather than being incorrectly renamed as a Start/Stop Eliminator.
2006-2008 Terraza 3.9L V6 — Keep the Fitment Precise
Buick's period documentation confirms the 3.9L 3900 V6 in the Terraza.
The 2006 Buick brochure describes the available 3.9L engine and its Variable Valve Timing system, while GM's 2007 fleet guide also identifies the Terraza with the 3.9L V6.
The supplier Excel and supplied Vehicle Fitment image list:
2006 Buick Terraza — 3.9L V6
2007 Buick Terraza — 3.9L V6
2008 Buick Terraza — 3.9L V6
All three remain part of this Recontrol-X SKU.
However, the OEM Terraza material reviewed does not describe the 3.9L cylinder-deactivation behavior as explicitly as GM does for the 2018 Regal GS LGX.
For that reason, the Terraza section should not invent a V6-to-V4 or V6-to-V3 cylinder transition.
That is the technically responsible difference between a high-quality vehicle page and a generic template.
Smooth & Predictable Power Delivery
For a confirmed compatible AFM application, keeping the engine in full-cylinder mode reduces the need for the powertrain to move repeatedly between full-cylinder and reduced-cylinder operating states.
The value proposition should therefore center on:
Consistent engine operation — keeping compatible cylinder management in its full-cylinder state.
Predictable throttle response — reducing the change in engine feel associated with cylinder-mode transitions.
Stable power delivery — providing a more uniform operating character during everyday driving.
These are meaningful benefits without making unsupported claims that the module increases horsepower or torque.
True Plug & Play OBD-II Installation
The Recontrol-X supplier material shows direct installation at the vehicle's OBD-II diagnostic connector.
The installation concept is straightforward:
- locate the OBD-II port;
- insert the Recontrol-X module;
- allow the device to initialize;
- operate the vehicle normally.
No internal engine disassembly is part of this installation.
The module does not need camshaft replacement, lifter replacement or cylinder-head removal simply to perform its electronic disabler function.
Established AFM/DFM modules use the same general OBD-II, non-permanent architecture, supporting this category-level description without transferring competitor-specific guarantees to Recontrol-X.
Keep Factory ECU Settings — Removable and Reversible
The supplied Recontrol-X feature image explicitly states:
Keep Factory ECU
and:
Unplug it to restore factory settings with ease.
This is one of the most useful legitimate selling points contained in the actual product material.
The module should therefore be positioned as a removable electronic solution, rather than as a permanent flash tune.
This distinction matters for customers comparing:
- OBD-II AFM disablers;
- mechanical AFM delete kits;
- permanent ECU tuning.
With this product, the intended normal workflow does not require permanently replacing the underlying factory ECU calibration.
Intelligent Power Guard
The supplied Recontrol-X Features image explicitly identifies:
Intelligent Power Guard
as a product feature.
Therefore it is appropriate to retain this selling point.
However, no numerical power-consumption specification was supplied.
The page should not invent:
- standby current;
- battery-saving percentage;
- sleep-mode timing;
- number of days the vehicle can remain parked.
The strongest correct wording is simply that the module includes a supplier-described Intelligent Power Guard function for its connected electronic design.
Electronic AFM/DFM Disabler — Not a Mechanical Delete Kit
RC-AFM-DFM-01-44 is an electronic OBD-II module.
It is not:
- a mechanical AFM delete kit;
- a camshaft kit;
- a lifter replacement kit;
- an internal engine repair;
- a horsepower programmer.
That distinction is important because searches for “AFM delete” and “AFM disabler” frequently overlap even though the two solutions are technically different.
This product provides electronic cylinder-management control on compatible applications, not mechanical valvetrain removal.

Reviews
S&Q
Which vehicles does RC-AFM-DFM-01-44 fit?
The supplier fitment lists exactly four applications: 2006, 2007 and 2008 Buick Terraza with the 3.9L V6, plus the 2018 Buick Regal GS with the 3.6L V6. Match your exact year, Buick model and engine before ordering. No additional Terraza or Regal applications are included in this SKU unless separately documented.
Does this fit every Buick Regal or every Buick Terraza?
No. For the Terraza, this SKU only lists the 3.9L V6 for 2006-2008. For the Regal family, the supplier data specifically lists 2018 Regal GS 3.6L V6—not every Regal trim or engine. The GS designation is part of the vehicle identity and should not be omitted when checking fitment.
How does Active Fuel Management work on the 2018 Buick Regal GS 3.6L V6?
GM identifies the Regal GS 3.6L LGX V6 as using Active Fuel Management. Under qualifying conditions, AFM can deactivate cylinders 2 and 5 so the engine operates temporarily with four active cylinders, then restore full six-cylinder operation when required. The Recontrol-X disabler is intended to keep a compatible AFM system in full-cylinder operation.
Does installation require wiring, engine work or a permanent ECU tune?
The supplied Recontrol-X module is designed for direct OBD-II plug-in installation. Normal installation does not involve internal engine disassembly, wiring-harness cutting or a mechanical AFM delete. The supplied product material also identifies the unit as retaining factory ECU settings rather than requiring a permanent reflash.
Can I remove the module and return to the factory strategy?
Yes. The supplied Recontrol-X feature material specifically states that the module can be unplugged to restore factory settings. It also lists Intelligent Power Guard as a product feature; however, no numerical standby-current or battery-life specification is supplied, so no unsupported electrical figures should be assumed.
