What is VCM on Honda Crosstour?

Understanding VCM on Honda Crosstour
The Variable Cylinder Management (VCM) system is a feature found on Honda vehicles with V-type engines, including the Honda Crosstour. It is designed to improve fuel economy by deactivating some of the engine’s cylinders under light load conditions. Here’s a breakdown of the key points about VCM on the Honda Crosstour:
1. Function of VCM: The VCM system in Honda vehicles, including the Crosstour, is designed to improve fuel economy by deactivating some of the engine’s cylinders under light load conditions.
2. Disabling VCM: There are aftermarket products like the S-VCM Controller and VCMTUNER II that allow for the deactivation of VCM in Honda and Acura vehicles, including the Crosstour. These products are designed to reliably deactivate VCM and are considered to be smarter and safer alternatives to resistor-based tools.
3. Considerations for Disabling VCM: Before purchasing a VCM disabling kit, it’s important to check local laws and regulations to ensure that it is legal to use one in your area. Additionally, consulting with a Honda dealer for recommendations on which type of kit to use is advisable, as disabling the VCM system may sacrifice some fuel economy.
4. Community Opinions: Discussions in Honda Crosstour forums indicate that some owners have opted to disable VCM using products like VCMTuner2 and VCM Muzzler, expressing concerns about potential issues related to VCM and seeking solutions to mitigate them.
5. Long-Term Impact: There are differing opinions on the long-term impact of VCM and its disabling. Some users have shared their experiences with VCM-related issues and the effectiveness of aftermarket solutions, while others have expressed trust in Honda’s engineering and the continued use of VCM in their vehicles, including the Crosstour.
In summary, the VCM system in the Honda Crosstour is designed to improve fuel economy by deactivating some of the engine’s cylinders under specific conditions. However, there are aftermarket products available to disable VCM, and owners should consider legal and fuel economy implications before making a decision.

Does cylinder deactivation damage the engine?

Let’s use a example of a V-8 engine that deactivate to 4-cylinders , even if the load is light, 4 cylinders are doing the work that 8 cylinders normally would do. My answer is yes, deactivation of cylinders do speed up engine wear in the active cylinders , but I think it’s still Beneficial to use.

What is Honda VCM engine problems?

When VCM disengages, the engine then misfires if needing to clear the cylinder of oil. This unique type of oil consumption has led to premature failure of parts like spark plugs, catalytic converters, engine mounts, pistons/rings, and cylinder walls.

What does VCM mean on a Honda engine?

Definition. This technology enables a V-6 engine to provide full power on demand while also delivering impressive fuel economy.

What is the difference between VCM and non VCM?

Answer. Answer: When in VCM mode, the two halves separate, the valves are therefore no longer connected to the camshaft, and the cylinder is “off”. Unlike the Z3, the cam profiles for each intake valve in a given cylinder of the z2 are identical, just as they would be in a non-VTEC engine!

What are the symptoms of VCM?

The symptoms and signs associated with mild to severe acute VCM exposure-shortness of breath, cough, dizziness, headaches, respiratory depression, and CNS depression-could be due to any number of industrial toxins, particularly other volatile halogenated hydrocarbons.

Is cylinder deactivation unreliable?

If the engine is equipped with a cylinder deactivation system, we face a new potential failure mode. Increasing the valvespring pressure or just increasing the amount of lifter movement at speed may be enough to overwhelm the oil pressure keeping the lifter in full operation.

How does Honda VCM work?

While still providing the power expected from a v6 engine. One challenge when cylinders are deactivated is they no longer generate. Power which creates a power imbalance.

Can you disable Honda VCM?

CURRENTLY SUPPORTED MODELS. Position 40,50,60 (Disable VCM) is tunable between different climates. Users who have had to replace CTS sensors will now have a very precise way of disabling VCM as well as calibrating the dash temperature gauge. For cold climates like Alaska, a setting of 35-40 will work in most cases.

Is cylinder deactivation bad for an engine?

If the engine is equipped with a cylinder deactivation system, we face a new potential failure mode. Increasing the valvespring pressure or just increasing the amount of lifter movement at speed may be enough to overwhelm the oil pressure keeping the lifter in full operation.

Which cylinders does Honda VCM deactivate?

Intro to Variable Cylinder Management Technology
The 2005-2007 Honda 3.5L V6 is a VCM-1 engine and only does cylinder deactivation on cylinders 1-3 instead of 1-4 like the VCM-2 engine.
