So I recently installed the S-VCM thingy. My question is wheres this "ECO" light everybody keeps talking about? Is it the green bar above the rpm gauge that goes from green to white? If it is then I guess my s-vcm isn't working right as it's always green on the highway. Am I missing something?

What’s the S-VCM thingy?

Your eco mode button should be on your main dash to the left of your steering wheel. It looks similar to this

You are noting the Eco Assist System, more specifically the Ambient Meter ● The color of the ambient meter changes to green to indicate that the vehicle is being driven in a fuel efficient manner.
In regards to the VCM system, There is no indication whether or not the vehicle is running with cylinder deactivation

I join ProdGirl in asking, what is the S-VCM thingy?
It disables the VCM (variable cylinder management) system. When at cruising speeds the VCM disables half the cylinders to conserve fuel. In the past the VCM system has caused prematurely worn parts. Previously it was very noticeable and harsh when this took place, the technology seems to have improved because you can’t even notice it happen on the passport. Still people don’t like the idea so they buy the S-VCM to bypass it.

Ahh, so its an add on to bypass the VCM system. Got it, thanks.
Not sure why folks do that. Doing my research before buying the PP, reading the Odyssey and Ridgeline forums, this hasn't been an issue for a couple years now.

You may be one of the lucky one's but I definitely feel it!
The best way I can describe it is like driving a manual car in a low gear in traffic, alot of lurching and bucking, might be the vcm or this terrible transmission or both, not sure but what I can tell you is once I put the s-vcm all those issues went away. Also I paid for 6 cylinder and I want a 6 cylinder,im not worried about the extra $2 of fuel im going to use per week.

Not sure your cars age and mileage, but the vehicle is equipped with active motor mounts that help eliminate the engine vibrations when the VCM kicks in and the car is effectively running on an “imbalanced” 3 cylinder. The dealership can test each individual motor mount with the HDS to make sure they are responding in an appropriate fashion and activating when they should

I don't feel it and I am sensitive to that sort of thing. If VCM is a problem, why do I see so many 2016 and newer high mileage Odyssey's and 2017 and up Ridgelines with 120K or more on the clocks,... a few had nearly 200,000 miles and were running fine on non-rebuilt engines... I think a lot of this is internet rumor that somehow materializes into factual claims and paranoia. My opinion... really not worried about VCM.

My Passport is brand new with only 3500kms.
I cant be bothered getting the mounts checked as I'm on a very short 2 yr lease. It was enough for me to feel it and it bothered me so I plunked out the $80 for it, no biggie.

Woah, I've felt that slight bucking, lurching at times too while driving. Hopefully it's more the VCM than a bad tranny.

I think that feeling is the engine trying to decide if it should be in 3cyl mode or 6.
The way Honda has it set up is it come's on to soon, it should cut the cylinders once your up to speed. My truck was the same just that I could shut it off.

I owned a 2007 and 2010 Odyssey with VCM and both had 150K miles. I did not feel the transition. I now own a 2019 Odyssey and a Passport and don’t really feel it either. Perhaps on the 9 speeds what you feel is the changes in gear based on your throttle input. A steady on the gas makes a more comfortable ride.

Voice of reason. Thank you. I think people are way too hyper-focused on the slight jitter or what ever. Nervous throttle foot will exacerbate any unevenness.

Merry Christmas, I wonder if you can share where did you purchase this in Canada ? I googled and it shows US dollars price and it is far from the $80 you have mentioned? Secondly, would you be so kind to share impressions from us so far? Thank you in advance!!

Thank you, I choose to go with the USA version of this device. Were you not happy with the PP? What made you get rid of it
