Anyone installed the VCMTUNER - Disable VCM / ECO for Honda Odyssey, Pilot, Accord & More. yet on their 2022 Passport Trailsports?

Would love to hear tips and/or experiences you had installling and tuning it after.

Thanks in advance.

If deactivating the VCM makes you sleep better at night then get it. It's a simple install and there are scores of installation videos and testimonies online to help. Talking with experienced but independent local automobile mechanics is also a good idea, they can give you more qualified opinion than you can find online.

Will installing the VCMTUNER do any damage to your Passport? I can't imagine how if it's installed as directed, it's not changing anything but just tricking the engine to always continue using the full set of cylinders.
Do you even need it considering the perception that Honda has now gotten the deactivation tuning right and the claim of the active engine bushings are absorbing whatever vibrations remains? Maybe, maybe not. I've owned only Honda and Acura cars since I bought my 1999 Accord and I'm a member of several other Honda/Acura forums so I know that the makers of the VCMTUNER responded to the high demand for anti VCM measures in the Honda community. Despite the perception that's it's no longer needed there still strong demand for the VCMTUNERII in the Honda/Acura community and you actually have to join a waiting list before you can buy one. That means a lot of people in the Honda/Acura community are still worried about Honda's cylinder deactivation. I won't pretend to know better than them so I can't blame them...neither can I blame the folks who are disgusted by the VCMTUNER idea.

My wife prefers her cars completely stock and I'm not particularly interested in unnecessary modifications either but I installed the VCMTUNERII in her 2020 Passport Touring because I believe when we bought a V6 we should always have a V6. I took an informal poll here and several people reported that they have it installed and no error to report, I also talked with a local tech who I take my out of warranty Honda vehicles to and he said he's seen lots of it under the hood but no damage as a result of it so I went ahead and did the install and we have had no issue since then. I'm not home a lot and my wife has taken her Passport to our local dealer a couple of times without removing the VCMTUNERII but no one scolded her or even said anything.


I know Honda means well with it's fuel saving efforts but I'm leery of government mandated measures especially when those measures are implemented in a way to bridle long established science like the V6/V8/V12 combustion system. When cylinder deactivation comes on, only one set of cylinders is always deactivated and only one set is always working...how does that affect even wearing of the system?

There is strong online support for hobbling Honda's VCM system, there is also strong opposition. But one lesson I took to heart is the fact that there was also strong opposition to disabling the Honda Idle Stop System either with a gadget or by just pressing the button, many across Honda/Acura communities are of the opinion - "Just leave it on - The modern engine can handle it, the battery can handle it, the starter can handle it, they are all made extra tough for this...etc.", but we consumers don't have Honda's feedback data on these systems, the fact that Honda recently increased the warranty coverage of the starter motor and valve adjustments and it also released an update to stop the system becoming a problem after eight years of suspicion and complaints from owners was somewhat telling for me. It might just be generosity, it might also be because Honda has data that those two engine sections are being reported to be failing at a high rate so it's heading off a future class action lawsuit.


With that being said, I'm of the opinion that turning off electronic nannies and electronic limitations in a car is a personal decision, so to each his own.
