The function of the AST Smart ECO VCM module. The computer in your car must fulfill a number of requirements, including engine temperature, before the VCM is permitted to engage and ECO mode is made available. The computer permits VCM to activate and ECO mode to engage once it determines that the engine has heated to about 167 degrees F. The Engine Coolant Temperature Sensor [ECT1] and your computer are connected via a plug-in device called the Smart ECO VCM. This device adjusts the temperature the sensor measures in order to keep it below the level at which the ECO mode would activate. When this cannot guarantee that VCM will be inhibited (due to, for example, varying climatic circumstances or load settings), it can typically prevent VCM from activating while driving normally.
Why is the AST Smart ECO VCM module advantageous? Helps prevent the popular Honda + Acura vehicles’ ECO mode from activating aids in preventing premature failure, fouling, and spark plug misfire reduces unwanted engine vibrations Because the VCM engages, your car continues to run on all six cylinders for more power and responsive throttle. Directly Inline With Your Engine Coolant Temperature Sensor, Made with OEM Connectors + Terminals, Professionally Crimped and Soldered with Approved Tooling Plugs
How should the AST Smart Eco VCM module be installed? 1. Find the ECT1 (current coolant temperature sensor) (seen in the photo at the bottom of the page). 2. Disconnect the current connector while your engine is still cold. Before removing it, push the side with your thumb to unlock it. 3. Connect the engine’s AST Smart ECO VCM Module. It ought to “snap” into place as you listen. 4. Connect the engine connector you took out to the AST Smart ECO VCM Module. 5. Place the thermal switch so that the engine is in contact with it. *More thorough guidelines are included with the unit*
What functions do the various AST Smart ECO Modules have? Models SC and DC are the two variations of our product that we currently provide. The VCM can be reduced by over 90% using SC models because they are smaller and have a single fixed value. The VCM/ECO suppression level can be fine-tuned in the larger DC versions to match the vehicle and your driving style. These models also have a manually movable control knob. It can eliminate your ECO mode nearly 99% of the time if configured properly.

Can you switch off the Honda VCM?
You must buy a VCM Disabler in order to disable a VCM on a Honda. The product typically costs between $50 and $100. Disabling VCM takes about 30 minutes to complete.
Before turning off your Honda’s VCM system, there are a few things to think about. However, if you do choose to disable it, the procedure is rather easy to follow. Just remember to balance the benefits and drawbacks before making a choice.
Honda began utilizing VCM when?
Only a few Honda and Acura vehicles have been left to flounder in the years since VCM was first introduced in the 2005 Honda Odyssey.
Must I deactivate Honda VCM?
Disabling VCM should lower your car’s oil usage if the cylinder rings are not entirely worn out. The sooner you apply VCMTUNER to your car if high oil consumption is a recent issue, the less wear and damage your engine will sustain.
What’s the process of cylinder deactivation?
The force of a gas-air mixture combusting in an engine’s cylinders causes pistons to rise and fall, turning a central crankshaft. The force generated by the crankshaft’s rotation ultimately turns the wheels.
The mechanism closes the exhaust valves, which expel spent gases, and the intake valves, which suck in air when a cylinder deactivates. Additionally, fuel injection into the cylinder is stopped. The piston still goes up and down—it must because it is connected to the rotating crankshaft—but it is now merely a passenger.
Not just half of the cylinders receiving gasoline accounts for the increased efficiency. Your engine isn’t performing at its best when you’re not putting a lot of strain on it, like when you’re traveling at a constant speed. Pumping loss is the amount of energy lost when the pistons pull in and push out air.
If my Honda has a VCM, how can you tell?
VCM is undoubtedly a distinctive feature! A Honda engine with variable cylinder management (VCM) is made to deactivate a specific number of cylinders while driving in order to save fuel.
Check the engine cover to see if your Honda has a VCM. It will be identified as having VCM if such is the case.

What model Honda has VCM?
Honda Odyssey (USDM) EX-L and Touring Models only (J35A7) VCM-2 operating on 3, 4, and 6 cylinder vehicles equipped with VCM 2005 and after. Honda Accord V6 from 2008 to 2017 (excluding EX-L V6 6MT Coupe) Beginning with the 2013 Model, the VCM operates in 3- or 6-cylinder mode rather than 3-, 4-, or 6-cylinder mode.
Variable Cylinder Management
According to the driving conditions, fuel-saving technology called VCM (Variable Cylinder Management) automatically deactivates 1/3 or 1/2 of the cylinders. This reduces pollution and saves fuel.
The 2016 Honda Pilot is VCM equipped.
A new 3.5-liter, direct-injected i-VTEC V-6 engine with two-stage Variable Cylinder Management (VCM) cylinder deactivation technology is available in the 2016 Pilot. The 2016 Pilot will also come equipped with a stop-start capability, Honda’s first non-hybrid use of this technology, for increased fuel efficiency.
The 2015 Honda Pilot is VCM equipped.
Engine: The 3.5L J35 SOHC V6 engine that powers the Pilot has Variable Cylinder Management, or VCM. Through the shutdown of two or three cylinders during steady cruising at a light or moderate load, the VCM contributes to increased highway fuel efficiency.
Is there vibration from VCM?
According to the Acura representative from ACC, the vibration is normal because the VCM is a non-repairable problem because it generates an imbalance in the cylinders when it drops the three cylinders.
How do I disable Eco on my Honda Odyssey?
When merging into the freeway, you want to have as much force as you can muster. You might not be able to disable the Econ option on your Honda Odyssey depending on the model year.
Honda added the option to turn off Econ mode starting with the 2018 model year by depressing the green Econ button on the dashboard, which is located to the left of the gear selector. The fuel-saving mode will be disabled as a result until you push the button once more to turn it back on.
Since the Econ button was not included with earlier Odyssey models, there is no official way to turn off the feature without voiding your warranty.
Take a moment to evaluate your auto insurance coverage after checking to see if your Odyssey has an Econ defeat button.

The Honda Pilot 2022 does it contain VCM?
In order to maximize fuel efficiency, the 2022 Honda Pilot is equipped with idle-stop technology, an Eco Assist System, and Variable Cylinder Management (VCM). When necessary, that last one, VCM, can operate the Pilot on three cylinders to get the most miles per gallon. All of this contributes to the two-ton SUV’s 20 city mpg and 27 highway mpg in FWD form. Each statistic is reduced by 1 mpg for an AWD vehicle, to 19 and 26 mpg, respectively.
Cylinder deactivation: Is it bad for the engine?
Even while you may reduce your petrol costs by always aiming for the highest mileage, sometimes it comes down to the technology in your car. One of these technologies is the deactivation of cylinders. Typically, it can be found in V-6 and V-8 engines, particularly in pickup trucks (though it is starting to appear more often in smaller vehicles as well).
When you are already traveling at cruising speed, you don’t actually need that much power, even though a driver may need all eight cylinders when they are accelerating or pulling a boat. When the additional power is not required, the engine can deactivate part of its cylinders.
Cylinder deactivation will be used on even cars like the 2016 Chevy Camaro RS to give premium performance while also saving petroleum.
How does cylinder deactivation save gas?
In general, the more cylinders an engine has, the more gas is required to keep it going. Less gas can be utilized by running your engine with some cylinders off sometimes. Although cylinder deactivation has been shown to increase gas mileage, the improvement may not always be substantial. It doesn’t necessarily follow that cutting out half of an engine’s cylinders will result in twice as excellent mileage. Depending on the car and powerplant, the benefits can vary.
Does cylinder deactivation make it so you can’t accelerate?
Cylinder deactivation hasn’t always worked as well as the manufacturers had intended in the past. Cylinder deactivation, however, typically does not result in those issues with newer automobiles. Instead, it enables you to save money on fuel when you don’t need it and benefit from premium power when you do.
How much gas is saved by deactivating the cylinder?
According to Chrysler, switching between an 8- and 4-cylinder engine could be accomplished in 40 milliseconds with no fuel entering the empty cylinders. For the Hemi V-8 engine’s Multi-Displacement, Chrysler claimed a fuel-economy boost of between 10 and 20 percent.
What does it signify if the VSA light on my Honda Odyssey illuminates?
VSA, or vehicle stability assist, is a computer technology from Honda that works to make sure the tires have grip so you can stay on the road. When both the check engine light and the VSA light are on, the computer has likely identified a potential systemic malfunction.
Has the Honda Pilot been deactivated?
The most recent iteration of Honda’s Variable Cylinder ManagementTM, or VCM, technology is installed in your Pilot. The Pilot’s V-6 engine’s innovative fuel- and money-saving technology takes advantage of the fact that typical driving doesn’t always require the full power of all six cylinders. Cylinders are turned off to utilize less fuel when there is less demand on the engine. As a result, the engine transforms into a 3-cylinder engine when you’re traveling at a constant lower pace. The Pilot engine then becomes a 4-cylinder when you gradually increase the speed of the vehicle to a higher cruising pace. Naturally, you may always use the maximum V-6 power when necessary, such as for accelerating and ascending steep hills.
