Why didnt you get your engine looked at and fixed instead of disabling a fuel saving feature?jackrabbit000 wrote: ↑So I deactivated the VCM (Variable Cylinder Management) on my 2006 Honda Odyssey. Wow, what a difference...no more vibration, no more cutting in/out of 3 cylinder mode. The engine is so smooth and responsive, the way it should be. And, saves the engine mounts. Device took about 1 min to install and can be removed if the van goes in for service. Doesn't give any codes or CEL. $65 we'll spent. Anyone else buy the VCMuzzler? This thing works on all the 3.5L VCM engines.

If there was a problem they would have at-least stopped offering the engine. I would say that the issue might be some cylinders not firing properly( due to what ever other issues might be ).jackrabbit000 wrote: ↑Do you have a Honda or Acura with one of these engines. It's a joke. Causes more grief than anything and for all the technology put into it with active engine mounts that get destroyed by the engine going into 3 cylinder mode...it only gains about 1 mpg over the non VCM engine. It's not just my vehicle, it's the design that the problem and there is no way that Honda/Acura would admit that they screwed up manufacturing this thing. Deactivating the VCM is the best thing ever. Others have actually reported a 1-2 mpg increase in gas mileage.

I'm using it as well on my pilot. I have the gen 1 VCMuzzler for $59. I have been using it for almost three months now. I was one of the first 10 people who got it on piloteers. You should really thank the inventor of this devise verbatim on piloteers.org. He has invested quite a bit of his own time and money on this.jackrabbit000 wrote: ↑So I deactivated the VCM (Variable Cylinder Management) on my 2006 Honda Odyssey.

The reason I gave you that link is that it appears to indicate that Honda redesigned or modified the mount with a new part number. I presume that the new part would have a better life than the original.jackrabbit000 wrote: ↑Thanks for the link, I've seen this on a Honda TSB. I already replaced 2 rear engine mounts on my Odyssey and so have a lot of other guys. The problem is still from the engine deactivating 1/2 of the cylinders. Honda deactivates the 3 cylinders in the rear of the engine and runs only the front 3. This is what I think is destroying the engine mounts. Check this out:

typically whenever its a V configuration engine, it has equal number of cylinders on each side. manufacturers disable one side of the V so that it becomes a straight engine for the duration. for a V6 firing 4 cylinders is not an option. If it was a V8 then it would be possible to fire only 4 cylinders.

Not true, because the pilot is V6 and it can go into 3 OR 4 cylinder mode depending on speed and load.Supahhh wrote: ↑typically whenever its a V configuration engine, it has equal number of cylinders on each side. manufacturers disable one side of the V so that it becomes a straight engine for the duration. for a V6 firing 4 cylinders is not an option.

On piloteers he is offering to refurb the gen 1 units to gen 2 for $10 but I haven't bothered yet because I haven't experienced any issues with the 82 ohm resistor. If I do start experiencing VCM during very hot days in stop and go traffic then I'll just switch the resistor to 120 ohm myself. As I understand it, the 82 ohm resistor was not keeping the temperature low enough for people in the southern states with stop and go traffic due to higher ambient temperature. This shouldn't be an issue in Ontario.jackrabbit000 wrote: ↑You should see if he will send you a Gen 2 and return the Gen 1 when you receive it. Someone else did this and he was OK with it. The Gen 2 is a way nicer unit and more compact. It comes with the 82 and 120 ohm resistors but I bought the 100 ohm as well. Takes 30 secs to change out the resistors if needed.
I actually met verbatim, he dropped the Gen 2 off at my house. I did thank him and told him that this is an ingenious device that he made and for spending the time researching and sourcing all the different the connectors.

a) Some VCM engines are reputed to be suspectable to problems with very high oil consumption and fouling sparkplugs when operating in 4 and 3 cylinder modes. VCMuzzler prevents operation in the 4 and 3 cylinder modes. There was a huge class action lawsuit settlement in the US over VCM

Just to clarify, the lawsuit was not over the generation of engine that OP has. It was for the generation that was manufactured after the OPs car.l69norm wrote: ↑a) Some VCM engines are reputed to be suspectable to problems with very high oil consumption and fouling sparkplugs when operating in 4 and 3 cylinder modes.

it doesnt.

was the replacement done with the new part number? ( just curios )? If it was done under warranty doesn't necessarily mean that the new part number was used.bugsbunny01 wrote: ↑it doesnt.
Original mounts were good for 120k. All three were replaced under warranty
