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.

Does VCM save gas?

VCM (Variable Cylinder Management) is fuel-saving technology that automatically deactivates 1/3 or 1/2 of the cylinders, according to the driving conditions. This saves fuel and lowers emissions.

What year did Honda start using VCM?

Vehicles equipped with VCM
2005-10 Honda Odyssey (USDM) – EX-L and Touring Models only (J35A7) – 2005-2007 models are equipped with VCM-1 (3- and 6-cylinder operation) – 2008-2010 models are equipped with VCM-2 (3-, 4-, and 6-cylinder operation).

Does cylinder deactivation improve mpg?

Cylinder deactivation has been proven to improve gas mileage, but it may not always be by a significant amount. Just because you are shutting down half the cylinders in an engine doesn’t mean that you will get mileage that is twice as good! The actual benefits vary depending on the vehicle and powertrain.

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.

For cold climates like Alaska, a setting of 35-40 will work in most cases.

What is the function of VCM in Honda?

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

What does a VCM tuner do?

Some folks have the VCMTUNER/VCMTUNER II installed on their engine to negate Honda’s cylinder deactivation technology. Justification for this install includes wanting access to the full 6 cylinders at all time, elimination of engine hesitancy and prevention of damage to engine mounts.

How good is cylinder deactivation?

Gasoline engine cylinder deactivation
In gasoline engines, CDA essentially operates fewer cylinders at higher power providing displacement on demand. It optimizes engine performance by providing full power when required and increasing efficiency when less power is needed.

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.
