Description
VCM Control Specifically for the TLX 3.5L V6
The Recontrol-X RC-VCM-01-07 is designed specifically for supplier-listed 2015-2020 Acura TLX 3.5L V6 applications.
This engine restriction is important because the first-generation TLX was offered with both four-cylinder and V6 powertrains. Acura's own specifications confirm that Variable Cylinder Management is fitted to the 3.5L V6, while the 2.4L four-cylinder is not a VCM application.
That makes 3.5L V6 Only one of the most important fitment terms on the entire page.
Maintain Full Six-Cylinder Operation
Acura's TLX VCM system is designed to improve efficiency by deactivating the rear bank of three cylinders when engine demand is low enough. When additional output is required, the system returns to full six-cylinder operation.
The Recontrol-X harness is intended for owners who prefer the compatible engine to remain in full-cylinder operation, reducing VCM mode transitions and providing a more consistent engine operating state.
This should be marketed as VCM control, not as a horsepower tuner or mechanical engine modification.
Four Adjustable Resistance Settings
The integrated selector provides:
68Ω / 82Ω / 100Ω / 120Ω
The supplier recommends 82Ω as the initial selection and allows resistance to be changed when operating conditions require adjustment.
Because the unit is manually adjustable, the page should not describe it as automatically adapting to temperature or climate.
ECT1 Inline Installation
RC-VCM-01-07 installs inline at the ECT1 coolant-temperature sensor connection.
The normal installation procedure consists of accessing the ECT1 connector, inserting the harness and selecting the appropriate resistance setting.
It is not an OBD-II module, does not require a permanent ECU reflash and is not a mechanical VCM delete kit.
Removable Design
Because the harness is an external inline component, the original sensor connection can be restored by removing it. This provides a reversible solution without permanently rewriting ECU calibration.

S&Q
Which Acura TLX does RC-VCM-01-07 fit?
Supplier fitment lists 2015-2020 Acura TLX equipped with the 3.5L V6 only. Match both the model year and engine before ordering.
Will it fit a 2015-2020 TLX with the 2.4L four-cylinder engine?
No. The supplier specifically lists 3.5L V6 Only, and Acura's official specifications show VCM on the V6 while the 2.4L four-cylinder does not use VCM.
How does VCM operate on the TLX 3.5L V6?
Acura documents a two-stage VCM strategy that can deactivate three of the engine's six cylinders under suitable lower-load conditions and return to six-cylinder operation when additional output is required.
Does installation use the OBD-II port?
No. The Recontrol-X harness installs inline with the ECT1 engine coolant-temperature sensor circuit in the engine compartment.
Can I use the ECO light to confirm VCM has been disabled?
Do not rely on that method for the TLX. Established VCM-controller guidance specifically lists 2015+ Acura TLX among vehicles without a dashboard ECO light directly correlated with VCM activation.
