Why I hate Honda & Acura VCM

Honda, Acura, and many other carmakers use cylinder deactivation as way to save fuel economy. Many people claim the fuel economy savings are negligible and the engine and other components may suffer from additional wear and tear.
Honda has been equipping VCM or variable cylinder management on their V6 engines for a while now. In the case of my Acura TLX, whenever the VCM activated the car would experience shaking that could be felt through the whole car. Passing power is reduced and the overall smoothness of the car was impacted.
There are a few VCM disabling devices on the market now including vcmuzzler, s-vcm, and vcmtuner. In this video I show how to install the vcmtuner and review the results.
I recommend this as a good DIY project if you have some basic wrenching and electrical skills. All DIY repairs or modifications you perform to your car are made at your own risk. I assume no liability for anything you choose to do to your car, before, or after watching one of my videos.

The cylinders are disabled by disabling their valves. This creates a vacuum inside the cylinder, sucking oil into the cylinder, and burning off the oil when the cylinder is reactivated. This is a major flaw with this method of cylinder disabling.

This is why I got the 6 speed manual accord.... it has the J35z3 (same V6 motor, minus VCM).

One day I was like u know what let’s change transmission fluid and o boy it fixed the VCM problem I don’t know how but It sure did now I change my transmission fluid every 10000 miles….

Great video and explanation! I experience the shaking in my car too I'm thinking of ordering one from svcm to install on my J series v6 Crosstour but im worried about the cooling too but they had a chart on it that I don't understand that maybe you might... It was a little hard to hear you over the music also.

@timothyhigginson9804 3 года назад

We own a 2014 Honda Odyssey with AVCM. it runs as smooth as ever. We cannot tell when it is engaged. When we drive on the freeway at 65 mph, we can get literally over 35 mpg. Again, we really do not notice the change in smooth running with eco mode.

@danjoe22 2 года назад

given the year of your vehicle you probably have the vcm version that disables only two cylinders instead of sometimes 3. I have read this system is better than the version of vcm that shuts down 3 cylinders at times. I was not as lucky with my 2010 honda Accord. I experienced spark plug misfiring due to oil infiltration into the cylinders but no other problems. I installed the vcm muzzler two years ago and all problems are now solved. Glad to hear you got one of the good ones!

@robertneal6878 Год назад

Good info about the after effects of Honda’s ill conceived system to conserve fuel. Though this post lacked detailed info on installing the S- VCM disabler. Getting to the plug on the coolant hose is a pain in the @$$. Push on the connector release rather than pull on it (as I did, er tried). Park the vehicle and let it sit for an hour. Keep the key fob far away from the vehicle. At least 20 feet from what I read. The key fob may activate signals that send codes which could come up while installing the device. I heeded that fore mentioned advise and have had no issues so far. Remember, those fluid filled motor mounts are Expensive! Though not as much as a rebuilt engine would cost due to the adverse effects of the VCM.

@speedborb3324 7 месяцев назад

I actually kinda like the VCM in my Acura. The vibrations are annoying but I do a lot of road trips and the better MPGs are nice. I do keep a quart of oil on me in the car because I heard some horror stories of the VCM causing oil burn.

I’m going to say this even tho I’m not sure what it is but I have a 2017 Honda Accord V6 touring sedan and it has a 6 speed auto, sometimes when I’m cruising at 80km/h-50mph the car stays in 5 gear for about 30 seconds and it has kind of like a drone sound because the car stays in 2,000/2,300 rpms until it finally shifts into 6th gear and the rpms drop to 1,400 rpms, the car is completely stock I don’t know if is something of the transmission programming or is that VCM that at 80km/h the car switch to 3 cylinder

@Yurboiisilly2 3 года назад

I have this same car. Do you notice the vibration in the steering wheel as well? Or when cruising at 65+mph? If so, then it’s definitely the VCM. I’m gonna order a disabler and see how it goes.

@reedhensley 3 года назад

See my only concern about this is the coolant temp. The computer changes how the car run when it is not warned up. Different fuel levels and what not. I dont like the fact that using that is fundamentally changing how the car should be running when it's up to operating temperature

@viksvehicles 3 года назад

I definitely understand that concern, I was on the fence about buying it but I haven’t noticed any ill effects since installing it, only a bunch of positives. My highway mpg has improved, there’s no annoying NVH when the cylinders used to shut off, and the passing power is always there now. If there are any bad side effects I haven’t really experienced them.

@reedhensley 3 года назад

@@viksvehicles I dont see how its possible for your highway mpg to improve when you are using all the cylinders

@TheRockacer22 3 года назад

@@reedhensley If you ride the gas in an attempt to hold constant speed this will improve your mileage on highways. The reason for this is that the 3 cylinder mode doesn't really maintain speed as well as it should so when you ride the pedal in attempt to maintain 60-70 mph, the 3 cylinders work overtime and use up more gasoline than if the 6 cylinders were working at a lower rpm. Basically its too inefficient at 3 cylinder mode to maintain cruising highway speed above 50 mph. It gets worse on interstate when you try to go 75-80, having the 3 cylinder mode kick in then and you will see once you let go of the pedal the speed drops way to too quick causing you to push on the pedal more and use up more gas.

@travelingrailfan4634 3 года назад

@@reedhensley when I’m 3 cylinder mode and u put down the pedal just a little it’s staying in 3 cylinder mode or 4 cylinder mode but those cylinders that are active are working harder than if u just had all 6 running. Engine has more continuous power, so therefor never is working as hard

Not really, it only turns on when you’re on part throttle at a steady speed. If you give it any acceleration it will go back into 6 cyl mode for full power. It’s the sound and vibrations that annoy me the most when VCM is active.

@nosirragsg Год назад

We passed 120K miles (2014 Ody) and #3 plug started fouling from sludge build up on seizing the piston rings thus causing oil bypassing rings getting to the spark plug.. Honda recommended replacing piston rings $7K, basically whole motor rebuild. This is caused from the VCM over time continually bypassing this #3 cylinder. Just hope that when it happens to yours it still has a warranty. Honda is very aware of this and will first do a plug swap hoping it will get you past the warranty....

With Tuner gas GPM = 20 with VCM GPM=27. But the tuner stopped the engine oil burning. See Honda service teck bulletin 13-085. Honda lost a law suite and gave odyssey 8- year warranty for owners to bring in their vehicles to have the piston rings replaced due to premature oil burning. Notice odyssey doesn't use timing chain but a timing belt. This means higher maint4enance cost.

@juantoledo4857 3 года назад

The reason is because the vcm wears down the seals on the cams from all the constant vibrations caused by 2-3 cylinders not firing causing oil leaks and also creating negative vacuum within the cylinder itself causing oil to enter and being burnt once the cylinder fires up again, people run into low oil and then the cams and just about everything near or around the cams run dry. Just always be aware of oil levels and when the time comes, replace o rings and seals.
