Description
VCM Control Designed for the 2013-2018 Acura RDX
The Recontrol-X RC-VCM-01-05 VCM Disabler Harness is designed for supplier-listed 2013-2018 Acura RDX applications. Unlike an OBD-II AFM/DFM module, this product installs inline at the ECT1 engine coolant temperature sensor connection, providing a removable method of controlling compatible Acura Variable Cylinder Management operation without permanently reflashing the ECU.
Acura officially confirms that this RDX generation uses VCM. The original 2013 system could vary between different active-cylinder configurations depending on engine demand, while later versions refined the strategy to provide extended reduced-cylinder operation before returning to full six-cylinder output when additional power was required.
Maintain Consistent Full-Cylinder Operation
VCM is designed to reduce the number of active cylinders when full engine output is unnecessary. The purpose of the Recontrol-X harness is to keep a compatible RDX from entering that reduced-cylinder operating mode.
For the driver, the relevant benefit is more consistent full-cylinder operation and fewer VCM mode transitions. The product should not be advertised as increasing horsepower, torque or fuel economy; it controls cylinder-management behavior rather than changing the engine's factory output.
68Ω / 82Ω / 100Ω / 120Ω Selectable Resistance
A genuine differentiating feature of this Recontrol-X product is its four-position resistance selector.
The available settings are:
68Ω · 82Ω · 100Ω · 120Ω
The supplied instructions recommend starting with 82Ω and adjusting when required according to operating conditions. Because the selector is manually adjustable, this product should not be described as an automatic or self-adjusting VCM controller.
ECT1 Inline Installation
Installation takes place under the hood at the ECT1 connection:
- Access the engine area.
- Disconnect the ECT1 connector.
- Install the Recontrol-X harness inline.
- Select the appropriate resistance value.
- Verify normal vehicle operation.
No mechanical VCM-delete parts or permanent ECU flash are required.
Removable Electronic Solution
Removing the harness and restoring the original ECT1 connection returns the vehicle wiring to its original configuration. This makes RC-VCM-01-05 fundamentally different from a mechanical engine modification or permanent performance tune.

Reviews
S&Q
Which Acura RDX years does RC-VCM-01-05 fit?
Supplier fitment lists 2013 through 2018 Acura RDX. No 2012 or 2019+ RDX applications are included in this SKU.
Does this product fit the newer 2019+ Acura RDX?
No 2019+ RDX appears in the supplied fitment data. Acura changed the RDX powertrain generation for 2019, so this listing should remain strictly limited to 2013-2018.
What does VCM do on the Acura RDX?
Acura's VCM system reduces the number of active cylinders under suitable lower-load conditions and restores full-cylinder operation when more engine output is required. Acura specifically documents VCM on this RDX generation.
Does this VCM disabler plug into the OBD-II port?
No. RC-VCM-01-05 is an ECT1 inline harness installed at the engine coolant-temperature sensor connection under the hood.
Is this a permanent ECU modification?
No permanent ECU reflash is part of the supplied installation method. The harness works through the ECT1 sensor circuit and can be removed to restore the original connection.
